cluster.eecs fileservice unresponsive

by

We are seeing a high load on cluster.eecs, resulting in NFS fileservice requests being delayed or failing. This affects all project shares hosted on cluster.eecs, and any services dependent on files there. Notably, this includes many research group websites.

Staff are investigating.

Staff continue to look into fileservice issues, but cluster.eecs has been responding normally since about 11:30am.

Ultimately at fault was a failed Instructional LDAP server. cluster.eecs currently shares fileserver resources with Instructional fileservice, and the dependence on Instructional LDAP caused cluster.eecs fileservice to become unresponsive.

The configuration of the NetApp fileserver has been updated to completely eliminate dependence on Instructional LDAP service. We are evaluating options to separate Instructional fileservice from cluster.eecs, to better isolate service needs.
