Operations News
- 2.1.14-13 Facilities upgrade complete.
- We have received word that a 2.1.14-15 version of CASTOR may be forthcoming.
- Kashyap's Elasticsearch query script has been rolled out to CASTOR headnodes. Users are encouraged to test it and report any bugs.
- 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.
- LHCb's remaining batch of 2014 disk servers have been deployed into production.
Operations Problems
- Major problems have been found with the draining script when we tried to drain an ATLAS disk server. The accounting was reporting obviously wrong numbers (negative number of files left on node), and the drain 'finished' without moving all files from the node. We have contacted CERN and are awaiting a response.
- A new service class called 'cedaRetrieve' has been created to allow CEDA users (aka Kevin) to manually stage files for retrieval.

Planned, Scheduled and Cancelled Interventions
Advanced Planning
Tasks
- Possible future upgrade to CASTOR 2.1.14-15.
- Resume draining on the ATLAS instance once draining issues resolved.
- Switch from admin machines: lcgccvm02 to lcgcadm05
- New VM configured to run against the standby CASTOR database will be created as a front-end for dark data etc queries.
- Replace DLF with Elastic Search
- Correct partitioning alignment issue (3rd CASTOR partition) on new castor disk servers
Interventions
Staffing
