RAL Tier1 Operations Report for 11th January 2017
Review of Issues during the week 11th to 18th January 2017. |
- We have been seeing SAM SRM tests failures for CMS. These are owing to the total load. On Friday an adjustment was made to the number of transfers Castor allocates to the newer three disk servers - which may help but not resolve the problem.
- LHCb have reported a problem accessing some files - and a GGUS ticket is open about this.
Resolved Disk Server Issues |
- None
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.
Ongoing Disk Server Issues |
- GDSS665 (LhcbRawRdst - D0T1) failed on Saturday 31st Dec. Two disks in the system were replaced and it was returned to service on Friday 6th Jan.
- GDSS780 (LHCbDst - D1T0) failed on Thursday 5th Jan. It was returned to service the following day - initially in read-only mode. The BIOS and IPMI firmware were updated.
Notable Changes made since the last meeting. |
- On Thursday 5th Jan the firmware was updated in the RAID cards in the Viglen '13 batch of disk servers.
- cvmfs client v2.3.2-1 has been deployed on all worker nodes.
- Increased the number of Castor transfer slots on the three newest disk servers in CMS_Tape.
- Load balancers have been introduced in front of the Site-BDII systems.
- The Castor Nameserver has been upgraded to version 2.1.15. This is the first step of the overall Castor 2.1.15 update.
- Migration of LHCb data from 'C' to 'D' tapes ongoing. Now a little over 70% done. Around 280 out of the 1000 tapes still to do.

Advanced warning for other interventions |
The following items are being discussed and are still to be formally scheduled and announced. |
Pending - but not yet formally announced:
- Merge AtlasScratchDisk into larger Atlas disk pool.
Listing by category:
- Castor:
- Update to Castor version 2.1.15. Dates announced via GOC DB for early 2017.
