Scheduled Downtime on 2010-11-08 Our Phoenix Cluster needs some maintenance operations that require a downtime. We will take the next maintenance window (first Monday of the month) to do them. In this case, the first working Monday is the 8th. It will start on Monday at 9:30 and last until Monday at 17:00. *The queues will be drained 20 hours before*. We will reserve an scheduled downtime until Tuesday at 17:00 for safety, but will open the queues and exit the downtime as soon as we check all the systems work properly. ---++!! Summary of interventions %TOC% ---++ Lustre Filesystem check (JT) We have to do a fsck on Lustre to ensure consistency. ---++ Upgrade glibc libraries (PF) On the rest of the nodes not applied yed, to fix a security hole.
