Operations News
- Draining - Atlas now draining again / LHCb also draining
- Tier 1 CASTOR stop and rebooted for Ghost vulnerability (and CIP)
- Facilities CASTOR rebooted for Ghost vulnerability
Operations Problems
- There is a problem with latest gfal libraries - not a new problem but Atlas are starting to exercise functionality and identifying these issues
- Atlas are putting files (sonar.test files) into un-routable paths - this looks like an issue with the space token used
- storageD retrieval from castor problems - investigation ongoing
- CMS heavy load & high job failure – hot spotting 3 servers, files spread to many servers which then also became loaded. CMS moved away from RAL for these files. Need to discuss this issue in more detail.
- castor functional test on lcgccvm02 causing problems - Gareth reviewing
- 150k zero size files reported last week have almost all been dealt with, CMS files outstanding
- Files with no ns or xattr checksum value in castor are failing transfers from RAL to BNL using the BNL FTS3 server.
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
- Oracle upgrade (11.2.0.4) of preprod 9th Feb - will require a short outage
- Oracle PSU update - Tuesday Primary / Wednesday standby
