Dear List,
We have a cluster in Jewel 10.2.2 under ubuntu 16.04. The cluster is compose by
12 nodes, each nodes have 10 OSD with journal on disk.
We have one rbd partition and a radosGW with 2 data pool, one replicated, one
EC (8+2)
in attachment few details on our cluster.
Currently, our cluster is not usable at all due to too much OSD instability.
OSDs daemon die randomly with "hit suicide timeout". Yesterday, all
of 120 OSDs died at least 12 time (max 74 time) with an average around 40 time
here logs from ceph mon and from one OSD :
http://icwww.epfl.ch/~ymoulin/ceph/cephprod.log.bz2 (6MB)
http://icwww.epfl.ch/~ymoulin/ceph/cephprod-osd.10.log.bz2 (6MB)
We have stopped all clients i/o to see if the cluster get stable without
success, to avoid endless rebalancing with OSD flapping, we had to
"set noout" the cluster. For now we have no idea what's going on.
Anyone can help us to understand what's happening ?
thanks for your help
