The NICS archival storage, HPSS, will be down for maintenance from 8 am until 11 am EST.
-
Kraken will be down for preventive maintenance from 8 am until 8 pm on Thursday, March 8. At this time, Kraken’s operating system will be upgraded to CLE 3.1. Users should relink their codes after the upgrade, although a full recompile may be necessary. Users should also re-submit their jobs to the queue after this maintenance as all jobs will be deleted from the queue during the upgrade.
GRAM5 services will be unavailable for approximately 12 hours after Kraken has been returned to production.
The Lustre file system on Kraken will also be upgraded from version 1.6 to 1.8. Because Lustre is a scratch filesystem, users are highly encouraged to archive their files to HPSS or otherwise safeguard their data. See http://www.nics.tennessee.edu/CLE3.1_upgrade for the most up to date information.
