Operations News
- Draining - Atlas now draining again as some space has been freed
- new client box (for db data dumps nsfinds etc)
- SL6 tape server built
Operations Problems
- Atlas are putting files (sonar.test files) into un-routable paths - this looks like an issue with the space token used. Brian / Rob actions below.
- There is a problem with latest gfal libraries - not a new problem but Atlas are starting to exercise functionality and identifying these issues
- 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
- CASTOR for Facilities SL6 Upgrade - Wed 25th Feb
- Upgrade Oracle DB to version 11.2.0.4 (Late February?)
