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. (anticipating 5.6.9), and awaiting any updates for LB.
