Hi cephers,
We are facing a scrub issue. Our CEPH cluster is using Trusty / Hammer 0.94.1 and have almost 320 OSD disks on 10 nodes.
And there are more than 30,000 PGs on cluster.
The cluster works fine until last week. We found the cluster health status start display "active+clean+scrubbing+deep".
Some PGs scrub ok but next second another PG start to scrubbing (or deep scrubbing) everyday.
We did not change the parameters of scrub. It should scrub once per day and deep scrub once per week.
Has anyone experiences with this incident？
Best wishes,
Mika
