Hello everyone!
I have built two clusters with old hardware, which is lying around, the
possibility to upgrade is there.
The clusters main usecase is hot backup. This means it's getting written 24/7
where 99% is writing and 1% is reading.
It should be based on harddisks.

Hello,
Is it possible to somehow sync a ceph from one site to a ceph form another site?
I'm just using the cephfs feature and no block devices.
Being able to sync cephfs pools between two sites would be great for a hot

If you do it, like Sebastian told you, you would automatically deploy osd's.
For a beginner I would recommend to do it semi-automated, so you know a bit
more what's going on.
So first do the "ceph orch device ls" which should print every disk, in all
nodes.
Then I recommend to zap device

Also the message in the error is not very meaningful.
For example, if I forget to install python3, the "python3 is not installed"

Hello,
When you deploy ceph to other nodes with the orchestrator, they "just" have the
containers you deployed to them.
This means in your case, you started the monitor container on ceph101 and you
must have installed at least the ceph-common package (else the ceph command
would not work).

Check if all your daemons indeed are running in the according containers on

If that is the case, you can get rid of the old rpms and install the new
