The new infosec database server is running Ubuntu 24.04. Can I just tell you how excited I was to have to run systemctl daemon-reload after editing fstab and trying to mount a new disk?

@jerry any issues with wal-g?

@jerry nasty. I’m using backblaze b2 and living with the occasional unannounced maintenance windows.

If Hetzner ever creates a s3 service, I will be very tempted to move all of my infrastructure to Hetzner.

I just left the building I helped design (ISS HQ, now the IBM Atlanta office), which is the reason I moved to Atlanta, for the last time.

Peace out.

Ok friends, it’s getting on to time to upgrade the Infosec.* db to Postgres 16 (currently on 15). I am going to take this opportunity to move to a new server with more memory. My question is this: I want to go with zfs snapshots for backup. I’ll be using mirrored nvme disks (by default, but that could be changed). What is the best drive configuration for that sort of setup?

@jerry you didn’t ask but if you are still (also) using wal-g, I had to update to the latest version of wal-g (version 3) when I moved to postgres 16

@jerry FYI I didn’t need to change any of the wal-g setup or configs. I simply swapped out the binary and it just worked

@jerry is it bad that I just swapped out the binary and continued on as-is? :)

@jerry oh also note that I was forced to upgrade when I updated to the latest Ubuntu LTS. I’m pretty sure it was the move to postgres 16 that required the wal-g upgrade but maybe not?

You could test to see if the old version of wal-g still works with postgres 16 but the release notes do include a lot of bug fixes so 🤷‍♂️

@jerry I don't know how you install, but the wal-g snap shudder in Ubuntu 24.04 is the old version. I did this:

wget https://github.com/wal-g/wal-g/releases/download/v3.0.0/wal-g-pg-ubuntu-20.04-amd64
sudo mv wal-g-pg-ubuntu-20.04-amd64 /usr/local/bin/wal-g
sudo chmod +x /usr/local/bin/wal-g
