Bet these are all on /dev/sda2 file system.

I can't tell what file system or device these are on, but it appears
to succeed without error. Therefore the VM is advertising discard
support to the guest. But what is calling fstrim? It appears to not be
fstrim.timer. We still don't know whether it might be the cause of
problems elsewhere in the storage stack that might explain why the
Btrfs file system you care about is being corrupted.

10 days.

"weekly" for systemd timers means "monday at 00:00" local time. Which
is what you're seeing in the first line, but not the second.
