RAL Tier1 Operations Report for 29th November 2017
Review of Issues during the week 23rd to 29th November 2017. |
Current operational status and issues |
Resolved Disk Server Issues |
- GDSS776 - (LHCbDst D1T0) crashed 14/11/17. GDSS776 is now ready to go back to full production mode.
Ongoing Disk Server Issues |
- GDSS698 - FSProbe Error on GDSS698 - Failed disk has been replaced and is being rebuilt.
- GDSS740 - RAID Partially Degraded. Failed disk has been replaced and is being rebuilt.
Limits on concurrent batch system jobs. |
- CMS Multicore 550
Notable Changes made since the last meeting. |
- Re-distribution of data in Echo onto the 2015 capacity hardware is now complete. There are now 8PBytes of usable space in Echo. However, there is some data rebalancing to be done before upping the quotas so the VOs can make use of the extra space.
- Intervention to migrate the MySQL DB to a new MariasDB Galera cluster for the 'prod' FTS instance has been completed.
- Echo configuration modified to allow Atlas an additional 500TB of space on Echo bringing their current total to 3600TB.
Entries in GOC DB starting since the last report. |
