Electrical maintenance in one computer room May 2nd to 10th

During May 2nd to 10th there will be an electrical maintenance in one of
our computer rooms.

This is due to an upgrade of the electrical facilities to accommodate our
new cluster.

Akka, Ritsem and Sarek will be turned off completely, including login
nodes, during the whole period. Jobs that have a walltime extending into
the above time frame will not be allowed to start.
This means that during the days leading up to the time frame Akka will
seemingly have free nodes available but jobs will will not start.

We will also do some maintenance on the /pfs/nobackup filesystem during
this period. I.e. there will be no access to files in /pfs/nobackup
at least for part of the downtime.

It is advisable to make sure that any important data on /pfs/nobackup is
copied to safe storage before this. Remember that /pfs/nobackup does NOT
have a backup and files might get lost during filesystem maintenance due
to unforeseen events.

We apologize for any inconvenience this may cause.
