- Elastic Search infrastructure has been fixed by James – we need to put tools on the admin node.
- Plan to ensure PreProd represents production in terms of hardware generation are underway. A student will be starting soon with the task of investigating visualisation and querying solutions for CASTOR use.
- Deployment of disk servers is due to restart next week.
Operations Problems
- Incorrect service classes in castor.conf on disk servers, Atlas issues resolved by Rob. Other non production issues identified by Bruno - Fix planned.
- low level db locking issues continue (various VOs) - has been reported to the developers at CERN.
- A potential race condition which could result in data loss has been seen on CMS (2.1.14-13) while investigating a file that would not migrate to tape. CERN have been notified.
- Atlas Xrootd proxy issues - investigation starting.
- CMS xroot issues
- Facilities castor error
- LHCb possible IO problems - ticket raised and investigation started.
- Need to update dteam and ATLAS VOs' voms-servers
Blocking Issues
Planned, Scheduled and Cancelled Interventions
- Switch-off of compatibility mode for Tier 1 Name Server
- Upgrade of Facilities CASTOR from 2.1.14-11 to 2.1.14-13.
Advanced Planning
Tasks

- Resume draining on the ATLAS instance (again, once name server compatibility mode change complete)
- Switch from admin machines: lcgccvm02 to lcgcadm05
- Replace DLF with Elastic Search
- Correct partitioning alignment issue (3rd CASTOR partition) on new castor disk servers
Interventions
Staffing
- Castor on Call person
- Chirs Monday - Friday
- Somebody - Weekend
- Staff absence/out of the office:
