Dear Eugen,
We have a scenario of DC and DR replication, and planned to explore RBD
mirroring with both Journaling and Snapshot mechanism.
I have a 5 TB storage at Primary DC and 5 TB storage at DR site with 2 different
ceph clusters configured.
Please clarify the following queries
1. With One wa
Hi,
I would suggest wiping the disks first with "wipefs -af /dev/_your_disk" or
"sgdisk --zap-all /dev/your_disk" and try again. Try only one disk first.
Is the host visible by running the command: "ceph orch host ls". Is the
FQDN name correct? If so, does the following command return any errors?
Hi,
Yes, like it always do

The problem is that the ubuntu packages for the ceph pacific release will
not be supported for ubuntu 22.04. We were wondering if the ceph client

Hello,
I had a problem after I finished the 'cephadm adopt' from services to docker
containers for mon and mgr. The fsid of `ceph -s` is not the same as the
/etc/ceph/ceph.conf. The ceph.conf is correct, but `ceph -s` is incorrect. I

I'm trying to add a new storage host into a Ceph cluster (quincy 17.2.6). The
machine has boot drives, one free SSD and 10 HDDs. The plan is to have each HDD
be an OSD with a DB on a equal size lvm of the SDD. This machine is newer but
otherwise similar to other machines already in the cluster t

We've run into a problem during the last verification steps before
publishing this release after upgrading the LRC to it =>
https://tracker.ceph.com/issues/65733
After this issue is resolved, we will continue testing and publishing
this point release.
Thanks for your patience!

For our customers we are still disabling mclock and using wpq. Might be
worth trying.

Hi Alexander,
We have configured the parameters in our infrastructure to fix the issue, and
despite tuning them or even set it to the higher levels, the issue still
persists. We have shared the latency between the DC and DR site for your
