Bug ID: 51350
Summary: solr stress out the NFS server
Product: Wikimedia Labs
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: Infrastructure
Assignee: [email protected]
Reporter: [email protected]

Classification: Unclassified
Mobile Platform: ---
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.
