For some reason, /srv is not using /dev/mapper/ruthenium--vg-tank (was ruthenium reinstalled recently?).
Because of that, ruthenium is going to run out of space and soon fail all operations. We can mount that and move /srv there, but it needs to stop using it.
Two question: can we have downtime and do this? Why did this happen, was this incorrectly setup on reinstall or something?
