And where is the manual for bluestore? -----Original Message----- From: mj [mailto:lists@xxxxxxxxxxxxx] Sent: dinsdag 25 september 2018 9:56 To: ceph-users@xxxxxxxxxxxxxx Subject: Re: PG inconsistent, "pg repair" not working Hi, I was able to solve a similar issue on our cluster using this blog: https://ceph.com/geen-categorie/ceph-manually-repair-object/ It does help if you are running a 3/2 config. Perhaps it helps you as well.
