filesystem

We are currently experiencing difficulties with the servers for the filesystem mounted at /nfs/proj13.

On the morning August 28th, 2013 we will briefly disrupt the GPFS filesystem to reboot servers. This is necessary to upgrade the GPFS system. The in-place upgrade should only briefly interrupt service to the GPFS filesystem, and the outage should only last a few minutes. Running jobs should pause until the system returns to service.

Please contact OSC Help if you experience any problems.

We are experiencing some network performance issues on a cluster of servers involved with providing GPFS and some project filesystems. GPFS appears to be functioning acceptably, but proj01, proj02, proj03, proj08, and proj09 are not. Compute nodes attempting to write to these filesystems will see very slow write speeds.

The root cause has been identified as a damaged fiber optic cable. We will be replacing this cable, and expect an outage of less than one minute to the affected hosts.

Today, May 14 2013, at 12:45PM we will be temporarily removing one of the home directory servers from service to address some reliability issues. Users with home directories under /nfs/13 will experience a brief disruption in service. Logins will likely fail, and jobs will not run for these users.

We expect this outage to last for 15-30 minutes.
