Hello everyone,
I created a new ceph 14.2.7 Nautilus cluster recently. Cluster consists of
3 racks and 2 osd nodes on each rack, 12 new hdd in each node. HDD
model is TOSHIBA
MG07ACA14TE 14Tb. All data pools are ec pools.
Yesterday I decided to increase pg number on one of the pools with
command "ceph
osd pool set photo.buckets.data pg_num 512", after that many osds started
to crash with "out" and "down" status. I tried to increase recovery_sleep
to 1s but osds still crashes. Osds started working properly only when i set
"norecover" flag, but osd scrub errors appeared after that.
In logs from osd during crashes i found this:
