I have a cluster with 1 inconsistent pg. I have attempted the following
steps with no luck. What should my next move be?
1. executed ceph health detail to determine what pg was inconsistent
[ceph-admin@admin libr-cluster]$ ceph health detail
HEALTH_ERR 1 pgs inconsistent; 1 scrub errors
pg 1.959 is active+clean+inconsistent, acting [69,252,127]
1 scrub errors
2. executed ceph pg repair 1.959
3. after nothing happening for quite a while I decided to dig into it a
bit. What strikes me most odd is that all of these files seem to be
consistent using size, md5, and sha256. It's also a little concerning that
they are all 0 for size.
