Amarel Phase 1 Owners,

As announced previously, Amarel Phase 1 compute nodes and storage expired in July 2021.

We postponed removal of the Phase 1 hardware, in part, to compensate for delays we’ve faced in acquiring and provisioning Phase 5A. Now that the Phase 5A equipment is in-production, we need to remove the Phase 1 equipment as soon as possible.

We are planning to remove Phase 1 nodes and storage from owner allocations during next week’s maintenance window (Feb 15-16).

How will these changes be implemented?

(Case 1) Owners of later-phase nodes (Phase 2-5) will see Phase 1 nodes removed from their job partitions. Storage quotas for the /projects filesystem will be reduced from current values, accounting for the loss of Phase 1 storage. Note that actively owning any number of Amarel compute nodes (i.e., being an Amarel owner) qualifies one for 1 TB of /projects storage, so there is no situation where an owner of compute nodes does not have any /projects storage.

If your /projects storage utilization is over your quota after a quota adjustment, that renders your /projects storage space read-only (unwriteable) until you can move or delete enough data to get back under quota.

(Case 2) Those who own only Phase 1 nodes and storage will simply lose access to those resources. Please note that loss of /projects storage will result in loss of data stored there. If this case applies to you, I urge you to begin moving your data to an appropriate alternative storage resource immediately. Box.rutgers.edu is a good option, but the data transfer process may be slow.

Of course, let me know what questions or concerns you have.
