RAL Tier1 Operations Report for 17th February 2016
Review of Issues during the week 10th to 17th February 2016. |
- The OPN link to CERN continues to be busy - although less so than during the previous fortnight.
Resolved Disk Server Issues |
- GDSS671 (AliceDisk - D1T0) failed on Saturday (13th Feb). Following tests and a disk being replaced it was returned to service on Monday (15th Feb).
Current operational status and issues |
- There is a problem seen by LHCb of a low but persistent rate of failure when copying the results of batch jobs to Castor. There is also a further problem that sometimes occurs when these (failed) writes are attempted to storage at other sites. A recent modification has improved, but not completed fixed this.
- The intermittent, low-level, load-related packet loss seen over external connections is still being tracked. Likewise we have been working to understand some remaining low level of packet loss seen within a part of our Tier1 network.
Ongoing Disk Server Issues |
- None
Notable Changes made since the last meeting. |
- The Castor repack instance was updated from version 2.1.14.13 to 2.1.14.15.
- Ongoing Condor updates (to version 8.4.4) on batches of worker nodes.

Whole Site | SCHEDULED | WARNING | 23/02/2016 09:00 | 23/02/2016 12:00 | 3 hours | Warning on Site during an infrastucture upgrade. |
Advanced warning for other interventions |
The following items are being discussed and are still to be formally scheduled and announced. |
Listing by category:
- Databases:
- Switch LFC/3D to new Database Infrastructure.
- Castor:
- Update SRMs to new version (includes updating to SL6).
- Update to Castor version 2.1.15.
- Migration of data from T10KC to T10KD tapes (affects Atlas & LHCb data).
- Networking:
- Replace the UKLight Router. Then upgrade the 'bypass' link to the RAL border routers to 2*10Gbit.
- Fabric
- Firmware updates on remaining EMC disk arrays (Castor, LFC)
- Grid Services
- A Load Balancer (HAProxy) will be used in front of the FTS service.
Entries in GOC DB starting since the last report. |
- None
