In the early days of the Atos HPCF your PERM lived temporarily in Lustre while we waited for the storage infrastructure to be completed. On Tuesday 1 March 2022 at 09UTC during a 2 hour system session we switched to the new permanent location based on TrueNAS NFS, with greater capacity.
This relocation should have been transparent to you, so you don't need to do anything. On the days before the session all your data was being copied in the background from your Lustre to the new PERM, with the final sync happening during the system session to ensure a clean switchover. Your new PERM is now automounted when you access a node either interactively or via Slurm.
