We will start to enforce quotas on Hopper $SCRATCH and $SCRATCH2 file systems starting Monday, Apr 25. The default user quotas for $SCRATCH and $SCRATCH2 combined are 5 TB of space usage, and 5 Millions inodes (i.e., number of files and directories). Users over the quota limit will not be able to submit new batch jobs once the quotas are enforced.

We will need to take down the Hopper system tomorrow morning at 9am Pacific Time to install a crucial patch. At that time we will also reconfigure some of the DVS service nodes to a more optimal setting. The downtime is scheduled to last 8 hours.
Login nodes and access to the file systems will be available. Users can also submit jobs, though the jobs will not start until the maintenance has been completed.
