RAL Tier1 Operations Report for 28th May 2014
Review of Issues during the week 21st to 28th May 2014. |
- Grumbly problems with the WMSs reported last week ongoing. The developers have been contacted.
- Problem reported last week with some half dozen Atlas files were lost during the draining of a disk server at the end of February is now understood. This was an isolated incident. Draining has been resumed.
- There was a problem with on FTS2 last Friday (16th) which led to a ticket from CMS.
- The checksum checker found a corrupt LHCb file in Castor which has been declared lost.
Resolved Disk Server Issues |
- None.
Current operational status and issues |
- Nothing to report.
Ongoing Disk Server Issues |
- None
Notable Changes made this last week. |
- CVMFS Client version 2.1.19 in final stages of being rolled out to whole farm following successful testing so far.
- One new disk server has been deployed to CMS disk. (This replaced a server (GDSS758) that failed a couple of weeks ago).
- A new tape controller server (ACSLS) was put into operation yesterday morning (Tuesday 20th May).
Declared in the GOC DB |
Service | Scheduled? | Outage/At Risk | Start | End | Duration | Reason |
---|---|---|---|---|---|---|
lcgui02.gridpp.rl.ac.uk, | SCHEDULED | OUTAGE | 30/04/2014 14:00 | 29/05/2014 13:00 | 28 days, 23 hours | Service being decommissioned. |
Advanced warning for other interventions |
The following items are being discussed and are still to be formally scheduled and announced. |
- Provisional dates for the Castor 2.1.14 upgrade: Nameserver: Tuesday 10th June; Stagers: CMS- Tue 17th June; LHCb - Thu 19th June; GEN - Tue 24th June; Atlas - Thu 26th June.
- We are starting to plan the termination of the FTS2 service now that almost all use is on FTS3.
- Maintenance will be carried out on the diesel generator tomorrow morning (22nd May) from 09:00 - 11:00. Should we suffer a mains power failure during this time window we will not have generator backup.
- On Wednesday 28th May we plan to move the network switches for some Castor disk servers to the mesh network to alleviate a bottleneck. This will be during an at risk on Castor.
Listing by category:
- Databases:
- Switch LFC/FTS/3D to new Database Infrastructure.
- Castor:
- Castor 2.1.14 testing was largely complete, although a new minor version (2.1.14-12) will be released soon.
- Networking:
- Move switches connecting recent disk servers batches ('11, '12) onto the Tier1 mesh network.
- Make routing changes to allow the removal of the UKLight Router.
- Fabric
- We are phasing out the use of the software server used by the small VOs.
- Firmware updates on remaining EMC disk arrays (Castor, FTS/LFC)
- There will be circuit testing of the remaining (i.e. non-UPS) circuits in the machine room during 2014.
