           Summary: solr stress out the NFS server
           Product: Wikimedia Labs
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: Unprioritized

This morning we found out both beta and tools projects were "slow". The root
cause is some jobs running on the solr project which exhaust the NFS server
(labstore3) I/O operations.

The workaround is to reboot the instance solr-mw2.pmtpa.wmflabs to disable the
stressing job as instructed by Nikolas Everett

The Solr experiment should be run on a different NFS system than the shared
one. I guess a dedicated one.
