RAL Tier1 Operations Report for 27th November 2018

Review of Issues during the week 20th November to the 27th November 2018.
  • The batch farm was drained and rebooted, to apply the security patch for CVE-2018-18955.
  • CMS SAM tests are still appearing as “missing”. We believe that CMS is aware of this problem and are manually correcting it while working on a fix.
  • While completing the weighting up of the ClusterVision 17 storage nodes, the Ceph Manager Daemons crashed and were unavailable for 30 minutes. This did not impact any production work, as despite their grand name, they simply providing monitoring information about the cluster. We believe this is a bug in the web dashboard and have disabled it for now and informed the Ceph developers.
