RAL Tier1 Operations Report for 10th January 2018
Review of Issues during the week 3rd January 2018 to 10th January 2018 |
- Disk server gdss745 (AtlasDataDisk - D1T0) has failed with loss of all data on the server. The problem was triggered by a failed drive. However, errors seen on other disk drives while this one was rebuilding led to loss of the RAID6 array. There were around 960,000 files on the server - around half of which were unique. A post mortem investigation of this incident will be carried out.
- There was a problem with the Castor GEN instance yesterday morning (Tuesday 9th). Staff restarted some of the Castor process and the service was restored by the end of the morning.
- Patching ongoing for recent security issues.
Current operational status and issues |
- Ongoing security patching.
Resolved Castor Disk Server Issues |
- gdss736 (LHCb - D1T0) - Has been rebuilt and returned to production
- gdss756 (CMS - D1T0) - Disk server crashed double disk failure port 24,port 28, port 3 and port 8
Ongoing Castor Disk Server Issues |
- None
Limits on concurrent batch system jobs. |
- CMS Multicore 550
Notable Changes made since the last meeting. |
- The termination of the WMS service had been announced - with a drain (i.e. not accepting new jobs) planned to start on 1st February. However, as the WMS is not being used by VOs at the moment and security patches need to be applied urgently the drain was brought forward and started this morning (10th Jan).
- Other security patching done or underway.
Entries in GOC DB starting since the last report.
Ongoing or Pending - but not yet formally announced: Listing by category:
Key: Atlas HC = Atlas HammerCloud (Queue ANALY_RAL_UCORE, Template 841); CMS HC = CMS HammerCloud
