Hi,
I have a problem with crashing OSD daemons in our Ceph 15.2.6 cluster . The
problem was temporarily resolved by disabling scrub and deep-scrub. All PGs
are active+clean. After a few days I tried to enable scrubbing again, but
the problem persists. OSD with high latencies, PG laggy, osd not
responding, OSD was marked down and the cluster is not usable. Problem
appeared after failover when 10 OSD was marked as out.
I will appreciate any help or advice, how to resolve this problem.
Regards,
Miroslav
