RAL Tier1 Operations Report for 18th June 2014
| Review of Issues during the week 11th to 18th June 2014.
|
- On Friday (13th Jun) there was a problem with one of the FTS2 front-end systems - fixed by appropriate daemon restart.
- There was a problem with cream-ce01 which started failing tests on Friday (13th Jun). It was put into a downtime and drained out over the weekend after which its database was reset. It was returned to service on Monday (16th Jun).
| Resolved Disk Server Issues
|
| Current operational status and issues
|
- The CMS Castor stager update to version 2.1.14-13 took place yesterday (Tuesday) as planned. There were some difficulties caused by the disk server re-balancer initially after the upgrade. However, these were understood and the service was restored within the announced outage. Nevertheless there have been some ongoing problems and the service was placed in a 'warning' state in the GOC DB for the rest of the day and overnight. The problems are being followed up with the developers at CERN.
