cluster.eecs ran out of inodes

by

cluster.eecs ran out of inodes at 4:12am. We’ve increased the number of inodes by 20%. To prevent this problem in the future we will monitor the inode usage in addition to the space usage and adjust the inodes available before it runs out again.

Network cable switchover and disk upgrades for IRIS file servers on June 4th at 3pm

by

On 3:00pm, Tuesday, June 4th, 2013, the network cables for cluster.eecs and inst-fs.eecs will be replaced in an effort to create more easily managed infrastructure. In addition, disk upgrades will take place on all department filers to increase available space. Minimal interruption of service is anticipated. NFS and CIFS mounts should reconnect automatically, although some windows mounts may need to be re-mounted. Maintenance may extend as long as 5pm, though system interruption should be a very short part of this window.

project.eecs short disruption in service at 6:30pm today.

by

project.eecs will have a short disruption of service at 6:30 pm today. This maintenance should last no longer than 15 minutes, and home.eecs should takeover for project during the downtime. Most home directory accesses should recover gracefully from the disruption. Windows mounts may require a re-connection.

Apologies for the short notice. Normally at least 24 hours would be provided before the maintenance window, but this work is required to prevent a more serious problem.
