We have once in a while NFS timeouts on different login nodes, the user logged in experience them as a short hangs. This been going for some last week, but not that often. The last week it started to be very often and almost on all nodes. We've applied patch which is suppose to fix this issue. In order for changes to be picked up we need to restart Hexagon. Update 15:30: Hexagon is up again.

The disk space /work-common/shared/imr will not be available from 8:30 for a few hours. We will send a separate notice to affected users when the file system will be  available. We encourage users having data there  to copy data necessary for your runs during this maintenance to /work file system. All jobs referencing to /work-common/shared/imr will be stopped before the maintenance.
