Cirrus Migration to EPCCFS storage

14 Sep 2026

The current /work storage is coming to its end of life so on Wed 16 Sep 2026 weare moving to new storage mounted on Cirrus login and compute nodes as /epccfs.

There will be a full maintenance session (starting at 09:00 BST on Wed 16 Sep 2026) with no jobs running on compute nodes for this switch. During this maintenance session, the following high level steps will be followed:

  • All jobs Pending in the queue will be deleted
  • This step is necessary as jobs in the Pending queue before the switch will expect to be able to write to /work. As this will not be possible after the switch, any pending jobs would fail.
  • Current /work storage will be changed to read-only mode
  • /epccfs storage will be made available in read/write-mode
  • Final testing of /epccfs
  • Service returned to users

The current /work storage will remain available in read-only mode until at least 21 Nov 2026 for users to copy over any data they wish to access/keep on the new /epccfs storage.
