filesystem problem in LDAP server may have caused temporary authentication failures

by

One of the LDAP servers in our pair became unresponsive due to a filesystem problem. Some services (such as Jabber) had authentication problems during this time. The system is back online now after running fsck.

The current LDAP servers are old legacy systems slated to be replaced in the very near future. The configuration of these servers and the services that rely on it is non-optimal which results in problems with authentication to some (but not all) services that rely on LDAP.

The new LDAP system is in its final testing phases now and will completely replace the aging infrastructure we have now.

The problem with the system was detected by IT staff with one of our monitoring systems which alerted us. We are not aware of any impact to the community and have received no reports from anyone. If you experienced any authentication problems between 1-2am then please let us know by writing to help@eecs.berkeley.edu

Soda 4th floor switch hardware failure

by

A hardware failure of a network switch has affected part (but not all) of the wired network on the 4th floor of Soda Hall.

We are working to replace the failed switch, but if you need your device re-connected sooner you can contact the helpdesk at help@eecs or call 510-642-7777. Provide your device hostname, MAC address, and the port cable ID where your network cable is plugged into the wall, and we’ll move your device to another port so you will have service restored while we continue working on the failed switch.

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.
