Operations News
- 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.
- SL6 has been rolled out to LHCB headnodes, no serious issues encountered
- SL6 rollout to CMS headnodes scheduled for Tuesday and Atlas for Wednesday
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.
- CMS xroot redirector has been moved from lcgclsf02 to another temporary node (was causing issues on LSF02).
- CMS has been suffering from castor issues that are thought to stem from very full cmsDisk (was 3% free)
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.
- Upgrade of CASTOR headnodes to SL6 CMS Tuesday 9/12/14 and Atlas Wednesday 10/12/14 and Gen W/C 5th Jan
- Upgrade Oracle DB to version 11.2.0.4 (Late February?)
- Upgrade CASTOR to version 2.1.14-14 OR 2.1.14-15 (Early February)
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
