March-20
- dCache Upgrade Follow-ups:
- add CMS TFC config to xrootd door on SE node (https://www.dcache.org/downloads/xrootd4j/index.shtml)
- implement postgress backup script to copy DB to t3nfs02:/zfs/data01/swshare/postgres
- dcache after upgrade became too verbose and filled out /var/log partition; to fix the problem dcache restart was done on Sun Mar 15 (without user activity)
- Storage Cleaning due to almost no free space on dcache:
- deletion of leftover user data took several days. Too many (hundred thousands) files in single directories: dcache can't handle it
- overal clenup brought ~ 30% free space; next step is needed - check and clean ~150TB of mc, data dirs
- Slurm:
- add QoS (500 cpu/user) to quick partition
- EOS test configuration (enabled on Worker Nodes and UIs): since February no user feedback
- Monitoring:
- all configuration changes saved on hiera/puppet/gitlab
- most of this list was done remotely from home with no drop in efficiency in compare to work from PSI office
