Hello, Cephers,
after trying different repair approaches I am out of ideas how to repair
inconsistent PG. I hope, someones sharp eye will notice what I overlooked.
Some info about cluster:
Centos 7.4
Jewel 10.2.10
Pool size 2 (yes, I know it's a very bad choice)
Pool with inconsistent PG: .rgw.bu
Thank You for help, it is exactly that I need.

Just use collectd to start with. That is easiest with influxdb. However
do not expect to much of the support on influxdb.

Hi all,
The same server did it again with the same CATERR exactly 3 days after
rebooting (+/- 30 seconds).
If it were'nt for the exact +3 days, I would think it's a random event.
But exactly 3 days after reboot does not seem random.

I have a Luminous Ceph cluster that uses just rgw. We want to turn it
into a mult-site installation. Are there instructions online for this?
I've been unable to find them.

On which node should we add the "admin socket" parameter to ceph.conf. On
the MON, OSD or on what node?

admin socket = /var/run/ceph/$cluster-$type.$id.$pid.$cctid.asok # must be

Yes, check the output of 'perf dump', you can fetch the RBD image
information from that JSON output.

I read the 12.2.7 upgrade notes, and set "osd skip data digest = true" before I

We have plugins that monitors ceph as well and I use in production. Bellow

Hi all,
After the 12.2.6 release went out, we've been thinking on better ways
to remove a version from our repositories to prevent users from
upgrading/installing a known bad release.
The way our repos are structured today means every single version of
the release is included in the repository. T
`ceph versions` -- you're sure all the osds are running 12.2.7 ?
osd_skip_data_digest = true is supposed to skip any crc checks during reads.
But maybe the cache tiering IO path is different and checks the crc anyway?

It would be nice if ceph-deploy could select the version as well as the
release. E.G: --release luminous --version 12.2.7
Otherwise, I deploy a newest release to a new OSD server, then have to
upgrade the rest of the cluster ( unless the cluster is on a previous
release at the highest level )
