Hi Eugen,
warnings continue to spam cluster log.Actually for the whole picture of the
issue please see:
https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/VDL56J75FG5LO4ZECIWWGGBW4ULPZUIP/
I was thinking about the following options:
1, restart problematic nodes: 24,32,34,36: need to schedule with business
partners
2, restart problematic mds with trimming behind issue: 3,4,5: mds will
start up quickly, won't they? investigating...
mds 3,4,5 have logsegment item in segments list that are stuck in expiring
status, which break the trimming process. Growing segments lists draw
concerns overtime.
Any other ideas?
Thanks,
Ben
