Also tried deep-scrub and scrub, same results.
Also set noscrub,nodeep-scrub, kicked currently active scrubs one at
a time using 'ceph osd down <id>'. After the last scrub was kicked,
forced scrub ran immediately then 'ceph pg repair', no luck.
Finally tryed the manual aproach:
- stop osd.36
- flush-journal
- rm rbd\udata.dfd5e2235befd0.000000000001c299__4f986_CBDE52BB__2
- start osd.36
- ceph pg repair 2.2bb
Also no luck...
rbd\udata.dfd5e2235befd0.000000000001c299__4f986_CBDE52BB__2 at osd.36
is empty (0 size). At osd.80 4.0M, osd.2 is bluestore (can't find it).
Ceph is 12.2.10, I'm currently migrating all my OSDs to bluestore.
Is there anything else I can do?
