Contents
Operations News
- SL6 Headnode work - stress testing ongoing without incident. (using realistic jobs from Alastair / Andrew if possible)
- ATLAS have filled their available space in atlasStripInput, so we have paused draining pending deletions.
- Draining - latest estimate is to complete draining in 7 weeks, assuming no breaks.
- Webdav access for LHCb now working
Operations Problems
- gdss720 / gdss763 are both drained, out of production and currently being worked on by Fabric team
- gdss659 is still but will be decommissioned out of CASTOR.
- lcgclsf02 had another sshd failure on Wednesday. We believe this is due to the xroot service on this node spawning an excessive number of subprocesses, which ran into a hard limit in the OS. This will be resolved by shifting this node's xroot responsibilities over to a dedicated node.
- Last week's SRM SAM test failures on LHCB/CMS and callout on pluto have been explained, and are due to the details of our DB setup. The issue will be fixed when we upgrade to 2.1.14-14.
Blocking Issues
- grid ftp bug in SL6 - stops any globus copy if a client is using a particular library. This is a show stopper for SL6 on disk server.
Planned, Scheduled and Cancelled Interventions
- A Tier 1 Database cleanup is planned so as to eliminate a number of excess tables and other entities left over from previous CASTOR versions. This will be change-controlled in the near future.
Advanced Planning
Tasks
- Plan and publish SL6 deployment plans
- Plan to ensure PreProd represents production in terms of hardware generation are underway
- Possible future upgrade to CASTOR 2.1.14-15 post Christmas
- Switch from admin machines: lcgccvm02 to lcgcadm05
- Correct partitioning alignment issue (3rd CASTOR partition) on new castor disk servers
Interventions
- Upgrade Production headnodes to SL6 - first upgrade Tuesday 2nd December. Next upgrades (ATLAS and CMS) planned for 9th and 10th December.
Actions
Staffing
- Castor on Call person
- Rob
- Staff absence/out of the office:
- Rob - Out at least 1 day
- Brian - Out Tuesday-Friday.
