We were having an OSD reporting lots of errors, so I tried to remove
it by doing:
ceph orch osd rm 139 --zap
It started moving all the data. Eventually, we got to the point that
there's only 1 pg backfilling, but that seems to be stuck now. I think
it may be because, in the process, another OSD

Given that some group would like to store 50-100 TBs of data on CEPH and
use it from a linux environment, are there any advantages
I was wondering about performance differences between cephfs and rbd, so
I deviced this quick test. The results were pretty surprising to me.
The test: on a very idle machine, make 2 mounts. One is a cephfs mount,
the other an rbd mount. In each directory, copy a humongous .tgz file

I was just hoping that I could skip the Rocky8 installation altogether...

We have a Nautilus cluster that just got hit by a bad power outage. When
the admin systems came back up, only the ceph-mgr process was running (all
the ceph-mon processes would not start). I tried following the instructions
in
https://docs.ceph.com/en/latest/rados/troubleshooting/troubleshooting-mo
OK, I'll try to give more details as I remember them.
1. There was a power outage and then power came back up.
2. When the systems came back up, I did a "ceph -s" and it never
returned. Further investigation revealed that the ceph-mon processes had
not started in any of the 3 monitors. I looke

ability to start and stay running. Have you tried just restarting the
MDS / RGW daemons again?

But the MDS maps were gone, and now I'm trying to recover that. I was

Also, here was the change which added the --recover flag:

There you can see the old process described again.
Good luck,

We have a ceph cluster with a cephfs filesystem that we use mostly for
backups. When I do a "ceph -s" or a "ceph df", it reports lots of space:

usage: 1.5 PiB used, 1.0 PiB / 2.5 PiB avail

I have been trying to install Nautilus using ceph-deploy, but somehow

Hello,
I'm going down the long and winding road of upgrading our ceph
clusters from mimic to the latest version. This has involved slowly
going up one release at a time. I'm now going from octopus to pacific,
which also involves upgrading the OS on the host systems from Centos 7
to Rocky 9.

Actually, stupid mistake on my part. I had selinux mode as enforcing.
Changed it to disabled, and everything works again. Thanks for the
help!
