Hello Casper, did you found an answer on this topic? my guess is, that with "ceph pg repair" the copy of primary osd will overwrite the 2nd and 3rd - in case it is readable.. but what is when it is not readable? :thinking: Would be nice to know if there is a way to tell ceph to repair pg with copy from osd X. best regards, Mehmet Am 04.12.2019 um 13:47 schrieb Caspar Smit: > Hi all, > > I tried to dig in the mailinglist archives but couldn't find a clear > answer to the following situation: > > Ceph encountered a scrub error resulting in HEALTH_ERR > Two PG's are active+clean+inconsistent.
