[Tetralith-users] Urgent reboot of Tetralith's login node tetralith2 again

[Sebastian Thorarensen]

Dear Tetralith users,

unfortunately, we will need to reboot the login node tetralith2 (a.k.a.
tetralith.nsc.liu.se, tetralith-el9.nsc.liu.se) yet again, at 15:30 today.
Estimated downtime: 30 minutes.

The reason is the same as last time: a bug in the storage software is
causing directories to become inaccessible; and prevents filesystem
operations such as taking snapshots and deleting old project directories.
tetralith2 must be rebooted to clear the current problem.  We will also
downgrade the storage software on tetralith2 even further, to try to
prevent the problem from occuring again.  We are still working with the
storage software vendor to find a definitive solution.
