Item | Presenter | Notes | |
|---|---|---|---|
Operational Issues | mitigations have been communicated to ATLAS for the jobs using 5.6.0 clients reboot campaign | ||
Checksums issue with an ATLAS file | https://github.com/xrootd/xrootd/issues/2388 https://ggus.eu/index.php?mode=ticket_info&ticket_id=169360 Checksum requested before whole file is updated. No ability to do stale checksum check in ceph, so original checksum ‘sticks’ to the file. fix in place RAL side by clearing checksums after a write is complete | ||
cms-aaa naming convention | cms-aaa is the only remaining personality to use proxy/ceph as the xrootd service names Separate naming convention would be more appropriate, to have main/supporting (not so urgent). CC created, and sandbox is prepared and has been tested on a test host | ||
XRootD Managers De-VMWareification |
Option 2 preferred for efficiency, but Option 1 decided on Option 1 would be simpler to implement for a temporary fix, as the move would be reversed antares tpc nodes to be moved to an echo leafsw, to confirm ipv4 real estate with James hosts moved to rack, renamed and IP assigned. pending DI advertisement | ||
Compilation and rollout status with XrdCeph and rocky 8: 5.7.x | 5.7.2 published. 5.7.2 skipped on farm due to pfc bug, possible RAL release 5.7.3 equivalent with a fix for that and 5.6.0 client compatibility | ||
Shoveler | |||
On the fly Checksums | Added configuration to PoC: option to turn on/off Adler32 on-the-fly calculation. Proved ability to set XrdCks.adler32 attribute from “standalone” code (running from the command line), will incorporate this into PoC code next. (Wasted time looking for attribute in wrong file…) | ||

Site reports
Lancaster: Following on from last week, we were looking at the load reported by the (default) cmsd load reporting scripts, and they didn’t seem to match up to any numbers we could pull from the servers. We got distracted by other things before we could dive deeper.
