[Berzelius-users] Berzelius downtime on 23rd to and including the 26th of May

[Filip Polbratt]

Dear Berzelius Users,

Berzelius is open for jobs again.

The migration from the DDN lustre storage to VAST for project and home 
directories has now been completed.

Additionally, the software catalog has also been moved to a new location 
and some physical work was done to the storage fabric.

There are some new features available in SUPR after this migration. The 
decommissioning features for storage has been added to Berzelius. With 
this it is now possible for a PI to mark a storage resource as 
decommissioned in the SUPR portal and the data will be removed from the 
cluster.

Best regards,
Filip Polbratt
