ceph-mon using 100% CPU after upgrade to 14.2.5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On our test cluster after upgrading to 14.2.5 I'm having problems with the mons pegging a CPU core while moving data around.  I'm currently converting the OSDs from FileStore to BlueStore by marking the OSDs out in multiple nodes, destroying the OSDs, and then recreating them with ceph-volume lvm batch.  This seems too get the ceph-mon process into a state where it pegs a CPU core on one of the mons:

1764450 ceph      20   0 4802412   2.1g  16980 S 100.0 28.1   4:54.72 ceph-mon

Has anyone else run into this with 14.2.5 yet?  I didn't see this problem while the cluster was running 14.2.4.

Thanks,
Bryan
