I have this deep scrub issue in the index pool's pg's almost every week which made the cluster health error so I always need to repair that pg :/

Any solution that you have found so far?

Subject:  OSD Crash During Deep-Scrub

Hello,

A while back, I was having an issue with an OSD repeatedly crashing.  I ultimately reweighted it to zero and then marked out 'Out'.  Since I found that the logs for thoses crashes match https://tracker.ceph.com/issues/46490
.

Since the OSD is in a 'Safe-to-Destroy' state, I'm wondering the best course of action - should I just mark it back in?  Or should I destroy and rebuild it.  If clearing it in the way I have, in combination with updating to 14.2.16, will prevent it from misbehaving, why go through the trouble of destroying and rebuilding?

Thanks.

-Dave
