On Monday, July 21st there will be an emergency system outage on both Delta and DeltaAI to perform a corrective file system check (fsck) on the /work (aka scratch) file system. The fsck is needed to correct issues on the file system that are causing an increasing number of issues with files or directories that can not be removed or other IO errors. The issue is believed to be metadata only, there is no indication of any data corruption.

The system outage will begin at 7AM and last until noon CDT. In order to complete the unmount of /work processes on the logins that have open files on work will be killed and/or it is possible that the logins will need to be rebooted.

Adjust job wall time when submitting jobs to fit jobs into the time remaining before the maintenance begins.
