Re: Possible data damage: 1 pg recovery_unfound, 1 pg inconsistent

I don't think pg repair will work. It looks like a 2(1) replicated pool where both OSDs seem to have accepted writes while the other was down and now the PG can't decide what is the true latest version.

Using size 2 min-size 1 comes with manual labor. As far as I can tell, you will need to figure out what files/objects are affected and either update the missing copy or delete the object manually.

Hello Stefan,

I run this command yesterday but the status not changed. Other pgs with status "inconsistent" was repaired after a day, but in this case, not works.

instructing pg 32.15c on osd.49 to repair

Normally, the pg will changed to repair but not.

Does "ceph pg repair 32.15c" work for you?
