Perhaps this is a good time to announce that Triolith actually has two
login nodes, and that the second one is now ready for use.

They are identical (128GB RAM and 16 CPU cores of the same type as the
compute nodes).

The first one can be reached at the addresses triolith.nsc.liu.se and
triolith1.nsc.liu.se. The second one can be reached at
triolith2.nsc.liu.se.

The second login node has already been updated and restarted, so if
you want to continue working undisturbed on a login node during
today's service stop, you can choose to login to triolith2 instead.

During future upgrades, we will try to always upgrade the login nodes
one at a time, to ensure that one of them is always available. You can
also try the second login node if the first should fail (e.g due to a
hardware failure or running out of memory).
