Site reports
Lancaster: Not much to report, we’re unhappy with some of the behaviour we’re seeing in Ceph but haven’t quite put our finger on the issues yet.
slow backfill on new osd
We’re working on how best to separate LSST from Grid without just spinning up a new set of xroot servers for them.
Glasgow:
migration to alma8 on monday, later to pacific > pacific+admRestarting OSDs eventually fixed the backfilling slowness, data moving around at GB/s rather then MB/s. None the wiser for the root cause, or why these OSDs had problems. Some suspicion at QoS, but need to dig.
Glasgow:
Migration started, OS first.
