[Kelvin-users] Cluster head node reboots

[Sean McGrath]

Dear all and apologies for multiple posts,

In order to carry out system updates we will be rebooting the head nodes for the 
Kelvin, Lonsdale and Parsons clusters Wednesday the 13th of May 2015 as follows.

Kelvin - 10am
Lonsdale - 11am
Parsons - 12pm

During the reboots the clusters will continue to process jobs and the queue's
will remain up. Currently logged in users will be logged out though and you will
have to log back in to submit new jobs and check the results of finished jobs
etc.

We expect that each head node will be unavailable for approximately 5 to 10
minutes while we reboot them but they may be down for longer in the unlikely
event of an issue during the reboot.

Important, if you have any files open for editing when the head nodes are
rebooted changes may be lost or the files may be corrupted so please ensure to
save any open files before the reboot.

Apologies for any inconvenience this might cause and thanks for your patience.

Regards
