Due to a hardware failure in the SAN storage system, the clusters (lonsdale, parsons, kelvin) will now be taken offline.
We are taking this step as the storage system is now in a non-redundant state, and we wish to guard against potential data loss.
We expect to have a replacement unit delivered on Monday, and will have the systems back online as soon as rebuilds have finished. This could lead into Tuesday.
All queues will be unavailable at this time.
The GPFS cluster filesystems (
/gscratch) will also be unavailable during this period.
