RAL Tier1 Operations Report for 29th November 2017
Review of Issues during the week 23rd to 29th November 2017. |
- IPv6 issues have now been resolved – [Tier1] Unit 2 is master for IPv6 but there is no physical connections to that router from the switch core. Consequently the fail-over did not complete successfully. Once understood this was resolved 23/11/17.
Current operational status and issues |
- - Re-distribution of data in Echo onto the 2015 capacity hardware is now complete. There are now 8PBytes of usable space in Echo. Some data rebalancing has been done and the Atlas quota has been increased by 500TB.
- - The MySQL database behind the Production FTS instance has been moved to a new distributed MariasDB Galera cluster database.
Resolved Disk Server Issues |
- GDSS896 (CMS_DEFAULT) has been returned to full production
- GDSS771 has been returned to full production
Ongoing Disk Server Issues |
- GDSS753 - Faulty drive - Port 5:6. Being investigated
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.
