My work log from the third quarter of the year 2024. I intentionally made this verbose to make future admin's work easier when troubleshooting. The more keywords, error messages, etc that are listed in this log, the more helpful it will be for the future OSE Sysadmin.

- Today I billed Marcin for 11 hours in August
- I sent an email to Marcin letting him know that my September commitment was postponed until October, and that I'm hoping to get a lot of work done this month. I don't expect to be able to finish everything, but I do hope to at least migrate some of the websites before October 15th
Hey Marcin, I just sent you an invoice for my 11 hours working on hetzner3 in August. I have good news: my September commitment was pushed-back to October, so I have availability in September to make a lot of progress on provisioning hetzner3. I don't think I'll be able to fully finish this project before my next commitment in mid-October, but I do think I'll be able migrate some subset of your sites in this stretch.

- excellent; the sha256sums and full gpg output are identical on all three TOFUs; I have a very high confidence in their authenticity now
...
- I returned to work on reviewing and preparing the ansible roles
- I've chosen to use the ansible-role-firewall ansible role by mikegleasonjr because it's simple and powerful https://github.com/mikegleasonjr/
- unfortunately, I've discovered that, as soon as you add a firewall rule that uses the ipset module, iptables fails on-boot and you're left with a unfirewall'd server if you reboot!
- the fix for this appears to be installing the `ipset-persistent` package in apt, though the module doesn't do this for you
- I filed a bug report with the maintainer (even though it hasn't been updated in 6 years) https://github.com/mikegleasonjr/ansible-role-firewall/issues/43
- I also submitted a PR https://github.com/mikegleasonjr/ansible-role-firewall/pull/44
- in the meantime, I'm just going to edit the ansible role on the OSE config to install the `ipset-persistent` package

- I realized that the 3TOFU on wordpress plugins and themes is going to be very difficult, especially for any themes or plugins whoose releases are locked-up behind paywalls
- anyway, here's TOFU 2/3 (VPN, exit in Latvia) for the main software

- I sent Marcin & Catarina an email asking if they have a list of all the paid wordpress themes/plugins that they use
Hey Marcin, Hey Caraina, Do you have a list of all the wordpress plugins & themes that you use that are paid? I might need to get credentials from you to be able to download the latest version of these plugins & themes. Having a complete list will help with the migration. Please let me know if you have a list of the wordpress themes & plugins that you've bought and use.

- Marcin also responded to my last email, agreeing on this migration order
- he also said that the only candidate to retire was the old forums, but since I converted that to a dumb static HTML site, I said not to. It's trivial to migrate, unlike a DB-backed web app.

- I spent some time on the ansible roles, most of today was merging the old nginx config files to the new debian format
- it looks like I used to have two awstats sites for OSE and OBI. I've decided to combine those to just one
- Catarina responded with info about paid wordpress themes. She says:
- We have 3 licenses for Oshine (www.openbuildinginstitute.org, microfactory.opensourceecology.org, and store.opensourceecology.org) +
- 1 license for Enigmatic (www.opensourceecology.org)
- the licenses are split over two different accounts
- we did a confidential credential sharing, but I'm unable to login because — in addition to the username/email and password credential, the website sends an OTP to the email account registered for 2FA. This is giving me déjà vu
- fortunately I left some notes on this wiki before; apparently you don't even need to login to download the oshine release; it's publicly available here http://brandexponents.com/oshin-plugins/oshine.zip
- looks like the latest version of oshine is v7.2.2, released a few months ago on 2024-05-30 https://brandexponents.com/oshin-changelog/
-
- looks like the latest version of enigmatic is Version 3.6, released many years ago on August 2017-08-30
- we currently have v3.5 installed, so we do have an update to do
- I can't login to any of these accounts on my own, but Catarina forwarded me an OTP and I was able to get into her account

themeforest-2XwUOcbo-enigmatic-responsive-multipurpose-wp-theme-wordpress-theme.zipfrom

- the GET variable "Expires" is set to "
- anyway, I've saved these versions on my laptop's OSE VM for now. I hope I can do at least a 2TOFU before I copy them to our new server.
- I also downloaded the license info for the three paid products on catarina's themeforest

- I spent some more time working on the ansible roles
- I realized that wazuh 4.x is out, but our old install had 3.0 https://documentation.wazuh.com/current/installation-guide/wazuh-agent/wazuh-agent-package-linux.html
- I'm going to try to install wazuh 4.x on this new server
Sun Aug 04, 2024
- at the time of writing, here's the latest versions of mediawiki https://www.mediawiki.org/wiki/Version_lifecycle
- MediaWiki 1.42.1, current stable. Released 2024-06-27. EOL 2025-06 https://www.mediawiki.org/wiki/Special:MyLanguage/MediaWiki_1.42
- MediaWiki 1.39.8, current LTS stable. Released 2022-11-30. EOL 2025-11 https://www.mediawiki.org/wiki/Special:MyLanguage/MediaWiki_1.39
- There's also going to be a new LTS release coming-out in 2024-12, but I expect that we'll finish the migration by then
- good news: looks like Mediawiki signs their releases with PGP ☺
- the keys file doesn't appear to be on more than one domain; it has a lot of different people's keys https://www.mediawiki.org/keys/keys.txt
- the MediaWiki sourcecode is also on mediawiki.org, so that doesn't offer any additional out-of-bound auth verification of their public keys https://gerrit.wikimedia.org/
- the current LTS release is signed with Sam Reed's key (1D98 867E 8298 2C8F E0AB C25F 9B69 B310 9D3B B7B0), but I think we should just 3TOFU the keys.txt file above https://releases.wikimedia.org/mediawiki/1.39/mediawiki-1.39.8.tar.gz.sig
- at the time of writing, the latest version of wordpress is 6.6.1, released 2024-07-23
- wordpress doesn't have an LTS version :(
- and wordpress doesn't sign their releases :'(
- there's been a ticket open for adding release signing to the in-app upgrades since 2016 (8 years ago!), but that's not really what we want. We want release signing for downloading the installer https://core.trac.wordpress.org/ticket/39309
- I opened a bug report to just sign the damn releases as part of the release process with gpg like all other major foss projects, but I was given the runaround and they said they'll wait until core finishes the 8-year-old stalled ticket. perfect example of perfect being the enemy of the good https://meta.trac.wordpress.org/ticket/7574
- so I guess we'll just have to 3TOFU the latest wordpress release https://wordpress.org/wordpress-6.6.1.zip
- here's our 3TOFU script

Hey Marcin, We need to decide what order to migrate the sites from Hetzner2 to Hetzner3. Here's what I propose: 1. forum.opensourceecology.org 2. store.opensourceecology.org 3. microfactory.opensourceecology.org 4. fef.opensourceecology.org 5. oswh.opensourceecology.org 6. seedhome.openbuildinginstitute.org 7. www.openbuildinginstitute.org 8. www.opensourceecology.org 9. phplist.opensourceecology.org 10. wiki.opensourceecology.org Does that cover all of the websites? Did I miss any? The general idea is to do simpler & less-priority websites first, saving the trickiest and highest-priority websites for last. Do you agree with this order? Would you prefer some changes? Now is also a good time to consider if you want to retire any of these unused websites, if you'd like. Please let me know if you agree with this migration order.

- I updated Hetzner3 with some of the info that hetzner reported back to us
- we learned that our hetzner3 server was a
EX42-NVMemodel. For comparison, Hetzner2 was aEX41S-SSD. - we learned the 64G RAM is the max that this server can take
- we learned that our hetzner3 server was a

- I spent some time preparing our ansible roles & provisioning playbook
Wed July 31, 2024
- This morning I woke-up to some emails from Hetzner indicating that our Hetzner3 order is finished, and responding to my questions
>1. By default, is the two disks configured in a RAID1 array? Servers from server auction are without pre-installed OS, so that no Software-Raid is pre-configured. >2. Do we have any other RAID options? The server have two disks, so that you could install an Linux OS via installimage script. There you would have the option to install it without raid or raid1 or raid0 is possible with two disks. Please find information about installimagescript here: https://docs.hetzner.com/robot/dedicated-server/operating-systems/installimage/ >3. How many additional (empty/unused) disk slots does this dedicated >server have? What options would we have for adding additional disks to >this machine in the future, if needed You can add one additional NVMe or up to two additional sata SSD or sata HDD. >4. We ordered this because it has "M.2 NVME disks" as opposed to the >"SSD" disks. Can you confirm that the NVME disks are faster than "SSD" >disks? If not, please cancel our order and we'll purchase another >machine with 3x 512G SSD disks Usually NVMe SSD are faster than sata ssd. >5. Currently we have another dedicated server with "2 x 250 GB SATA 6 >Gb/s SSD". Can you please tell us the "Gb/s" throughput for this >server's disks? Unfortunately I don't have information about it. You should test it yourself on your server.
- so it looks like we did well snagging the auction for the last-available, lowest-price with "2x SSD M.2 NVMe 512 GB"
- I checked their server auction page again, and I do still see one server available at their lowest 37.72 EUR/mo price with 2x 512G NVMe disks, so I guess one listing doesn't necessarily mean that there's only one server available.
- after migration, we should end-up with a 25% full disk. If we ~triple our current disk usage before we retire this server, we have the ability to add two more non-NVMe SATA SSD disks in another RAID1, which we can partition-up as-needed for our backups, tmp files, etc (hopefully we can keep www and DB on the faster NVMe disks)
- their hardware page has info on the addon SSD disks that they lease, and their prices https://docs.hetzner.com/robot/dedicated-server/general-information/root-server-hardware/#drives
- it looks like their cheapest non-NVMe SSD is 8.50 EUR/mo for a 1T disk. Of course, we would need two for the RAID, so that means we can 4x our disk space in the future for an additional 17 EUR / mo. They also have a 3.84 TB SATA SSD for 37 EUR/mo, and they have both 16T and 22T SATA HDDs for 20.50 and 27.00 EUR/mo, respectfully.
- we also get a free 100GB "storage box" along with our purchase, which I guess is some external NFS mount. It's probably slow as hell, but we *could* use it for something like our two local copies of encrypted backup data. We also have this as part of our hetzner2 plan, but we don't use it.
- the free 100G storage box is named "BX10". We can even increase this to a BX11 (1T @ 3.20 EUR/mo), BX21 (5T @ 10.90 EUR/mo), BX31 (20.80 EUR/mo), or BX41 (40.60 EUR/mo)
- this is my first time setting-up a hetzner dedicated server (I inherited both hetzner1 & hetzner2)
- I was hoping for something like an in-browser KVM/VNC like SolusVM offers. Or to feed it 'cloudinit' like hetnzer cloud offers, but I don't see that as an option
- looks like they have scripts for installing a few disros. docs here https://docs.hetzner.com/robot/dedicated-server/operating-systems/installimage/
- and here's the general docs on their dedicated servers https://docs.hetzner.com/robot/dedicated-server/getting-started/root-server-guide/
- ok, they do offer a KVM-over-IP for installing custom distros. Apparently a technician has to physically plug-in to the machine, and you're given 3 free hours. After that it's 8.40 EUR/hr https://docs.hetzner.com/robot/dedicated-server/maintainance/kvm-console/
- the new server is now listed on our "Hetzner Robot" Server Page https://robot.hetzner.com/server
- the old server is listed as "EX41S-SSD #XXXXXX"
- the new server is listed more simply as "Server Auction #XXXXXXX"
- I sent another support request to hetzner asking which type of hardware we have
Hi, I have another question about possible disk upgrades to our newly-purcahsed server "Server Auction #2443019". Can you please tell us what type of server we ordered? Is it an AX? DX? EX? GEX? PX? RX? SX? Or what? I ask because your documentation page on what disk upgrade options are available has a lot of caveats (eg "only for the following servers" or "not available for XYZ"), so to know what our options are I need to know which server type we have. * https://docs.hetzner.com/robot/dedicated-server/general-information/root-server-hardware/#drives Please let us know which server type we have, so that that I can figure out what disk upgrade options are available (and their prices). Thank you,
- I probably should have done this before, but I checked the cloud hetzner offerings
- I didn't check it before because I expected it to be memory bound. I do want to stick with 64G of RAM
- indeed, the cheapest server with 64G of RAM in the cloud is 95.99 EUR/mo — but that also gives us 16 dedicated cores (AMD) and 360 GB disk. And, of course, it's easier to upgrade. But too expensive
- as said above, we *could* probably get-by with 16G of RAM. That's 23.99 EUR/mo with dedicated vCPU. 32G is with dedicated vCPU is 47.99 EU/mo. With shared vCPU, we get 16G RAM for 15.90 EUR/mo or 32G for 31.90GB/mo. But we can't increase the RAM beyond 32GB/mo on the shared vCPU systems
- therefore, I do think going with the dedicated server is our best bet due to the value on the RAM that we get.
- I also asked hetzner sales about possible memory upgrades. I don't think we'll need more than 64G of RAM, but it would be good to know if upgrading is possible
Hi, I have another question about possible memory upgrades to our newly-purcahsed server "Server Auction #2443019". Can you please tell us if our current configuration with "4x RAM 16384 MB DDR4" is the maximum RAM that this system can accept? Does the server only have 4x RAM slots? Or are there some empty ones? Is it possible to increase one or more of the RAM slots with >16G RAM chips? Please let us know what options we have for future memory upgrades on this new dedicated server. Thank you,
- I tried to shut down the hetzner3 server (to eliminate it as a vector until I've hardened it), but there's only an option to reboot :(
- I gave hetzner my ssh public key at order-time, and — yep — it's setup with the root user by default :(

- I'm reading through the guide on hetzner's `installimage` tool https://docs.hetzner.com/robot/dedicated-server/operating-systems/installimage/

- ok, I ran installimage
root@rescue ~ # installimage
- I selected "Debian"
- I selected "Debian-1205-bookworm-amd64-base"
- it dumped me into a midnight commander editor and said I could save with F10
- it said that "by default all disks are used for software raid" — that sounds good
- the "standard config" file that it gave me was too long to try to copy & paste, but the default RAID looked like what we wanted
- the default partition layout had a 32G swap, 1G /boot, and the rest allocated to '/'
- hetzner2 has a 488M /boot that's currently 84% full (using 386M). 386/1024 = 38% full, which is much better. That sounds good.
- hetzner2 has a 32G swap. It does get used, but it's currently using <1G. 32G should be fine.
- I thought about setting up an LVM. It would be a better idea than having everything on one disk, but it would inevitable require more maintenance. For the sake of keeping things simple for a non-profit that has no sysadmins on staff, I'm going to stick to "just allocate the rest to '/'"
- oh, cool, the config file said what our disks are (if it can be trusted). It says: SAMSUNG MZVLB512HAJQ
- looks like they're from 2017 https://ssd.userbenchmark.com/SpeedTest/401452/SAMSUNG-MZVLB512HAJQ-000L2
- samsung advertises them as having 3.5 Gbps sequental read + 2.9 Gbps sequential write + 460K random read iops + 500k random write iops
- I decided to accept all these defaults and proceed with the install
- oh, except I did change the hostname line
- ah shit, how do I send an F10 command over ssh? stupid midnight commander editor...
- I pressed Ctrl+[[ and that seemed to work
- the install finished in a few minutes

- I have to say that I was happy that it generated new ssh keys and that it said it was verifying some public key and doing some image verification.
- oh, and they disabled root password and ssh login with password. that's better than I expected from them. good.
- I ran `shutdown -h now`, and the server didn't come back. That's actually good. I wanted to see if I could shut the thing down (the safest machine is a machine that's off, especially before hardening), but the hetzner robot WUI didn't give an option to shutdown (only to reboot).
- after waiting 5 minutes with no pongs to my pings, I logged into the hetzner robot wui -> server -> reset tab -> Execute an automatic hardware reset, and I clicked "Send" https://robot.hetzner.com/server
- after a few more minutes with still no pongs to my pings, I logged into the hetzner robot wui -> server -> WOL tab -> clicked "Send WOL signal to server"
- after about 2 minutes, I started getting pings and was able to ssh-in as the 'root' user
- as soon as I got a shell from ssh, I quickly pasted-in my "jumpstart" provisioning and hardening commands to create a user for me, do basic ssh hardening, and setup a basic firewall to block everything except ssh

- alright, basic hardening is done.
- That's all I really wanted to achieve for now. Next I'd like to prepare some ansible playbooks to setup the rest of the basic hardening
- for now, I just want to leave this machine off in the meantime
- I attempted to shut it down again
- I left a ping open for 147 minutes, and I never got a pong back. So I'd say it's off. Great!
- it appears that I just have to trigger a WOL on hetzner robot WUI to turn it back on, which I'll do after I spend some time working on the ansible roles playbooks
Tue July 30, 2024
- Marcin gave me the go-ahead to order a "hetzner3" server and begin provisioning it with Debian in preparation to migrate all our sites from the CentOS7 hetzner2 server to this new server
- This is going to be an enormous project. When I did the hetzner1 -> hetzner2 migration, I inherited both systems (in 2017). For some reason the websites were split across both servers (plus dreamhost too iirc?). but I consolidated everything onto "hetzner2" and canceled "hetzner1" in 2018 https://wiki.opensourceecology.org/index.php?title=OSE_Server&oldid=298909#Assessment_of_Server_Options
- I'll be using ansible to assist in provisioning this server (and hopefully make it easier to provision future servers). Marcin expressed interest in lowering this barrier for others, as well.
- I noticed that 5 years ago I created a repo for OSE's ansible playbooks, but it's empty.
- I just added the LICENSE to this repo, and I plan to use it to publish our ansible roles/playbooks
- First thing I need to do is decide which server to buy from hetzner's dedicated serer offerings
- holy crap, not only are their server auctions *much* cheeper per month, they also don't have a one-time-setup fee (usually ~$50-$200?)
- I've written pretty extensively in the past about what specs I'd be looking to get in a future OSE Server migration https://wiki.opensourceecology.org/index.php?title=OSE_Server&oldid=298909#OSE_Server_and_Server_Requirements
- In 2018, I said we'd want min 2-4 cores
- In 2018, I said we'd want min 8-16 G RAM
- In 2018, I said we'd want min ~200G disk
- Honestly, I expect that the lowest offerings of a dedicated server in 2024 are probably going to suffice for us, but what I'm mostly concerned-about is the disk.
- even last week when I did the yum updates, I nearly filled the disk just by extracting a copy of our backups. Currently we have two 250G disks in a software RAID-1 (mirror) array. That give us a useable 197G
- it's also provisioned with all the data on '/'. It would be smart if we setup an LVM
- It's important to me that we double this at-least, but I'll see if there's any deals on 1TB disks or larger
- also what we currently have is a 6 Gb/s SSD, so I don't want to downgrade that by going to a spinning-disk HDD. NvME might be a welcome upgrade. I/O wait is probably a bottleneck, but not currently one that's causing us agony
- I spent some time reviewing the munin graphs
- load rarely ever touches 3. Most of the time it hovers between 0.2 - 1. So I agree that 4 cores is fine for us now.
- most of these auctions have a Intel Core i7-4770, which is a 4-core + 8 thread proc. That should be fine.
- somehow our varnish hits are way down. They used to average >80%, but currently they're down to 28-44%
- load rarely ever touches 3. Most of the time it hovers between 0.2 - 1. So I agree that 4 cores is fine for us now.
- I documented these charts and my findings on a new Hetzner3 page
- I looked through the listings in the server auctions
- I don't want one that's only 32G RAM (few of these are)
- It looks like some have "2 x SSD SATA 250 GB" and some have "2 x SSD M.2 NVMe 512 GB". If we can, let's get the NVMe disks with better io
- there is one with "2 x HDD SATA 2,0 TB Enterprise". More space would be nice, but not at the sacrifice of io
- questions I have for hetzner:
- how many disk slots are there? Can we add more disks in the future?
- by default, do all these systems have RAID-1? Do we have other RAID options?
- oh, actually, there was only one server available for less than 38 EUR/mo that had the 2x 512GB NVME
- I went ahead and ordered it
- I also sent a separate message to hetzner sales asking them for detailed info about the different read & write speeds of their HDD, SSD, and NVME offerings in dedicated servers
- I sent an email to Marcin
Hey Marcin, I just ordered a dedicated server from Hetzner with the following specs: * Intel Core i7-6700 * 2x SSD M.2 NVMe 512 GB * 4x RAM 16384 MB DDR4 * NIC 1 Gbit Intel I219-LM * Location: Germany, FSN1 * Rescue system (English) * 1 x Primary IPv4 While they had plenty of servers available with the i7-6700 and 16G of RAM, they only had one with 2x 512 GB NVMe disks (the others were just "SSD" disks). Those NVMe disks should give us a performance boost, so I snagged it while it was available. I did some reviews of our munin charts to determine our hetzner3 server's needs. For more info, see * https://wiki.opensourceecology.org/wiki/Hetzner3 Please let me know if you have any questions about this server.

- the backup is taking a long time. while I wait, I checked `top`, and I see `gzip` is using 80%-100%
- so it seems that gzip is bound by a single core. it could go much faster if it could be split across multiple cores (parallel processing)
- quick googling while I wait suggests that we could use `pigz` as a replacement to `gzip` to get this (admittedly low priority) performance boost https://stackoverflow.com/questions/12313242/utilizing-multi-core-for-targzip-bzip-compression-decompression
- there's other options too. apparently xz has native multi-treadded support since v5.2.0 https://askubuntu.com/a/858828
- there's also pbzip2 for bzip, and many others https://askubuntu.com/a/258228
- the other two commands that get stuck on one-core are `tar` and `gpg2`
- it looks like gpg also attempts to compress with xz. That gives us no benefits in our case because we're encrypting a tarball that just contains a bunch of already-compressed tarballs. So we could probably get some performance improvements by telling gpg to skip the xz compression with `--compression-algo none` https://stackoverflow.com/questions/46261024/how-to-do-large-file-parallel-encryption-using-gnupg-and-gnu-parallel
- finally (after ~30 min to generate the encrypted backup file), rclone is using >100% of CPU to upload it, so that's good. Our script does limit upload to 3 MB/s. I guess one improvement would be some argument to bypass that throttle
- it said the upload was going to take just under 2 hours, so I canceled it and manually ran the upload command (minus the throttle)
- upload speeds are now ~27-32 MB/s (so ~10x faster). It says it'll finish in just over 10 minutes.
- upload is done

- to make this easier for the next person, I created a README directly in the backups dir
[root@opensourceecology backups]# cat /root/backups/README.txt 2024-07-26 ========== The process to restore from backups is documented on the wiki * https://wiki.opensourceecology.org/wiki/Backblaze#Restore_from_backups Oh, the wiki is down and you need to restore from backups to restore the wiki? Don't worry, I got you. All backups are stored on Backblaze B2. You can download them with rclone or just by logging into the Backblaze B2 WUI. First decrypt the main wrapper tar with `gpg` gpg --batch --passphrase-file <path-to-symmetric-encrypton-private-key> --decrypt <path-to-encrypted-tarball> > <path-to-decrypted-tarball> For example: gpg --batch --passphrase-file /root/backups/ose-backups-cron.key --decrypt daily_hetzner2_20240726_160837.tar.gpg > daily_hetzner2_20240726_160837.tar Then you can untar the wrapper tarball and the compressed tarball inside of that. For example: tar -xf daily_hetzner2_20240726_160837.tar cd root/backups/sync/daily_hetzner2_20240726_160837/www/ tar -xf www.20240726_160837.tar.gz head var/www/html/www.opensourceecology.org/htdocs/index.php --Michael Altfield <https://michaelaltfield.net.> [root@opensourceecology backups]#

- I was able to load and edit the wiki; I spent some time adding some updates to the CHG article https://wiki.opensourceecology.org/wiki/CHG-2020-05-04_yum_update
- for some reason my browser keeps locking-up when all I'm trying to do is edit the text in the textarea for ^ this wiki article. I don't use the wysiwyg editor. I'm literally just editing text in a textarea; that shouldn't require any processing
- It took me ~20 minutes just to make a few changes to one wiki article because the page on firefox kept locking-up, sometimes displaying a spinning circle over the page
- I launched a new DispVM with *only* firefox running and *only* one tab open in firefox. The issue persisted, and the VM with the (idle) firefox on the edit page was taxed with 20-60% CPU usage; something is definitely wrong, but it's unclear if the bug is on our mediawiki server, my firefox client, or both
- anyway, I'm continuing with the validation steps
- I was successfully able to load the frontpage of all the 9x websites
- the logo at the top (and bottom) of https://oswh.opensourceecology.org/ was missing, but I'm not sure if that was the case before the updates or not
- I simply get a 404 on the image http://www.opensourcewarehouse.org/wp-content/uploads/2013/02/headfooter-logonew.png
- I guess the domain is wrong; we don't appear to use opensourcewarehouse.org anymore, so I guess this was an issue that predates our updates now
- everything else looked good
- the logo at the top (and bottom) of https://oswh.opensourceecology.org/ was missing, but I'm not sure if that was the case before the updates or not
- I logged into the munin. It loads fine
- I do see some gaps in mysql charts where everything drops to 0 for a few hours, which I guess is before/why Marcin did reboots again. My job now isn't to investigate this now, but I'm just making a note here
- otherwise munin is working; validated.
- I logged into awstates. it loads fine
- I just quickly scanned the main pages for www.opensourceecology.org and wiki.opensourceecology.org; they look fine
- I already tested edits on wiki.opensourceecolgy.org; they're working (setting aside the client-side lag)
- I was successfully able to make a trivial change to the main wordpress site, and then revert that change https://www.opensourceecology.org/offline-wiki-zim-kiwix/
- the only thing left is the backups, which have been running the background since shortly after the reboot
- the backups finished being created successfully
- the backups are currently being uploaded at the rate-limited 3 MB/s. they're at 39% now, and estimated to finish uploading in 1h10m from now.
- the upload is the last step; that's good enough for me to consider the backups functional
- that completes our validation; I think it's safe to mark this change as successful
- I sent an update email to Marcin & Catarina
Hey Marcin & Catarina, I've finished updating the system packages on the hetzner2 server. It's a very good thing that we did this, because your server tried and failed to download its updates from 484 mirrors before it finally found a server that it could download its updates from. As I mentioned in Nov 2022, your server runs CentOS 7, which stopped receiving "Full Updates" by Red Hat in Aug 2020. As of Jun 2024, it is no longer going to be updated in any way (security, maintenance, etc). At some point in the future, I guess all of their update servers will go down too. We're lucky at least one was still online. * https://wiki.opensourceecology.org/wiki/Maltfield_Log/2022#Wed_November_02.2C_2022 Today I was successfully able to update 434 system packages onto hetzner2. I did some quick validation of a subset of your websites, and I only found a couple minor errors 1. The header & footer images of oswh don't load https://oswh.opensourceecology.org/ 2. Editing the wiki sometimes causes my browser to lock-up; it's not clear if this is a pre-existing issue, or if the issue is caused by your server or my client I did not update your server's applications that cannot be updated by the package manager (eg wordpress, mediawiki, etc). If you don't detect any issues with your server, then I would recommend that we do the application upgrade simultaneously with a migration to a new server running Debian. I'd like to stress again the urgency of the need to migrate off of CentOS 7. Besides the obvious security risks of running a server that is no longer receiving security patches, at some point in the likely-not-too-distant future, your server is going to break and it will be extremely non-trivial to fix it. The deadline for migrating was in 2020. I highly recommend prioritizing a project to migrate your server to a new Debian server ASAP. Please spend some time testing your various websites, and let me know if you experience any issues.

Wed July 24, 2024
- Marcin contacted me a few days ago saying that the server needs reboots again
- I found that the last time we did a system packages update was in 2020, over 4 years ago. I strongly recommended that we update the system packages, and probably the web applications as well
- here's the link to the last time I updated the system packages in May 2020 https://wiki.opensourceecology.org/wiki/CHG-2020-05-04_yum_update
- I also noted that CentOS is now not only EOL, but it's also no longer receiving (security) updates.
- I warned Marcin about this approaching deadline in Nov 2022, and urged him to migrate to a new OS before 2024.
In my prior work at OSE, I've done my best to design your systems to be robust and "well oiled" so that they would run for as long as possible with as little maintenance as possible. However, code rots over time, and there's only so long you can hold-off before things fall apart. Python 2.7.5 was End-of-Life'd on 2020-01-01, and it no longer receives any updates. * https://en.wikipedia.org/wiki/History_of_Python CentOS 7.7 was released 2019-09-17. "Full Updates" stopped 2020-08-06, and it will no longer receive any maintenance updates after 2024-06-30. * https://wiki.centos.org/About/Product At some point, you're going to want to migrate to a new server with a new OS. I strongly recommend initiating this project before 2024.
- Here's the log entry https://wiki.opensourceecology.org/wiki/Maltfield_Log/2022#Wed_November_02.2C_2022
- I told Marcin to budget for ~$10,000 to migrate to a new server, as it's going to be a massive project that will likely require more than a month of full-time work to complete the migration
- Marcin said I should go ahead and prepare a CHG "ticket" article for the upgrade and schedule a time to do it
- I prepared a change ticket for updating the system packages on Friday https://wiki.opensourceecology.org/wiki/CHG-2024-07-26_yum_update
- I also noticed that I kept getting de-auth'd every few minutes on the wiki. That's annoying. Hopefully updates will help this (and other) issues go away.
- If we did a migration to debian, then we'd need to migrate to a new server
- previously when we migrated from hetzner1 to hetzner2, we got a 15x increase in RAM (from 4GB to 64GB). And the price of both servers was the same!
- I was expecting the next jump would have similar results: we'd migrate to a new server that costs the same for much better specs, but that's not looking like it's going to be the case :(
- Here's the currently-offered dedicated servers at hetzner https://www.hetzner.com/dedicated-rootserver/
- Currently we have 8-cores, 64G RAM, and two 250G disks in a RAID-1 software array. We pay 39 EUR/mo
- The cheapest dedicated server (EX44) currently is 46.41 EUR/month and comes with 14-cores, 64G RAM, and 2x 512G disks. That should meet our requirements https://www.hetzner.com/dedicated-rootserver/ex44/configurator/#/
- oh crap, we'd be downgrading the proc from the i7 (Intel® Core™ i7-6700) to an i5 (Intel® Core™ i5-13500)
- I'd have to check the munin charts, but I would be surprised if we ever break a load of 2, so that's still probably fine.
- I met with Marcin tonight to discuss [a] the system-level package upgrades, [b] the application (eg wordpress, mediawiki, etc) upgrades, and [c] the server migration
- I recommended that Marcin do the updates on staging, and described the risk of not doing it
- the problem is that the current staging environment is down, an d it may take a few days to restore it
- the risk is maybe a few days of downtime instead smaller change window during the update
- we agreed that I'll do the system-level package upgrades direct-to-production; Marcin accepted the risk of a few days of downtime
- Marcin also mentioned that Hetzner has a "server auction" page, which has some more servers that meet our needs at a slightly discounted price https://www.hetzner.com/sb/
- actually many of these are 37.72 EUR/mo, so they're actually *cheaper* than our current 39 EUR/mo. Great!
- there's >3 pages of servers for this 37.72 EUR/mo price. One of them has 2x 4TB drives (though it looks like spinning disks). This is a server graveyard built-to-spec for previous customers, it seems. We should be able to find one that meets our needs, so that means we'll easily double our disk and save ~15 EUR per year. Cool :)
