Operations News
- Proposed CASTOR face to face W/C Oct 5th or 12th
- New SRM version under testing. Works OK for a single job but hits trouble with many jobs.
- SL6 disk server config now testable, although needs solution for CV11 nodes and hooks to add WAN tuning.
Operations Problems
- CMS still upset. We have asked them to define exactly why their jobs are slow.
- Brian and Shaun investigating double putstart problem
- The gridmap file on the the webdav host lcgcadm04.gridpp.rl.ac.uk is not auto-updating - needed for lhcb and vo.dirac.ac.uk
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
- Stress test SRM poss deploy week after (Shaun)
Advanced Planning
Tasks
- Proposed CASTOR face to face W/C Oct 5th or 12th
- Discussed CASTOR 2017 planning, see wiki page.
Interventions
Staffing
- Castor on Call person next week
- RA
- Staff absence/out of the office:
- RA out Friday morning
- CP probably back Mon
- SdW out all week
New Actions
- RA to undo CMS's 'heart bypass' (unscheduled reads) to see if read rates are improved
* AL to look at optimising lazy download
- BD to set all non-target ATLAS nodes to R/Only to see if it stops partial file draining problem
- RA to investigate why we are getting partial files
- BD to chase AD about using the space reporting thing we made for him
- JS, RA and GS to propose dates for Oracle 11.2.0.4 patching.
Existing Actions
- SdW to modify cleanlostfiles to log to syslog so we can track its use - under testing
- SdW to look into GC improvements - notify if file in inconsistent state
- SdW to replace canbemigr test - to test for file that have not been migrated to tape (warn 8h / alert 24h)
- RA/JJ to look at information provider re DiRAC (reporting disk only etc)
- All to book meeting with Rob re draining / disk deployment / decommissioning ...
- RA to look into procedural issues with CMS disk server interventions
- BC to document processes to control services previously controlled by puppet
- GS to arrange meeting castor/fab/production to discuss the decommissioning procedures
- GS to investigate providing checks for /etc/noquattor on production nodes & checks for fetch-crl - ONGOING
- RA to get jobs thought to cause CMS pileup
- BC / RA to write change control doc for SL6 disk
- SdW testing/working gfalcopy rpms
- Someone - mice, what access protocol do they use?
Completed actions
- RA/GS to write some new docs to cover oncall procedures for CMS with the introduction of unscheduled xroot reads
- RA/AD to clarify what we are doing with 'broken' disk servers
- GS to ensure that there is a ping test etc to the atlas building
- BC to put SL6 on preprod disks.
- RA to remove Facilities disk servers from cedaRetrieve to go back to Fabric for acceptance testing.
