- 2012-11-26: Tusker Shutdown Dec. 17
Category: MaintenanceA December 17th shutdown is planned for Tusker. During the shutdown we will be performing maintenance on, and upgrading, the Lustre storage system which supplies the /work filesystem. We request users to remove as much data as possible from the /work filesystem between now and then to 1) ensure it will be possible to wait until after finals week (Dec. 17) and 2) to help minimize the time required to perform the upgrade. Additional disks will be added to the storage array to improve reliability of the system -- the less data there is to move and/or re-stripe, the faster this process will be.
Tusker will be made available immediately after this maintenance is complete.

Four new disk enclosures will be added to the Lustre file system serving Tusker. Details are being worked out in discussions with the vendor (Terascala), but the end result will be a more robust, and likely slightly larger, filesystem. Right now multiple RAID 5 disk sets are in service (as was required by the vendor). HCC has succeeded in negotiating a change to RAID 6, but the migration path is still being finalized.
