Site reports

Lancaster: As mentioned in storage, Dune root TPC hit by https: //github.com/xrootd/xrootd/issues/2202 at Lancs.

Had one slow OSD cause a lot of issues for ~12 hours this week. Coincided with a period of heavy CEPH traffic, and caused a lot of CEPHFS mounts to be dropped.

Putting first new storage nodes in a long time into production next week, any tips?

  • Tom: better control of number of placement groups that could be moving.

GlasgowHad a bad time of it due to getting too full - a lot of slow ops. This caused xroot load and service drops there. Tightened atlas belt a bit helped free up some space, and we’re rolling out meatier MDSs (double the RAM).

Glasgow: Sam build newer versions of xrootd on CC7 and 8.

✅ Action items
