Hi all,
I've a working couple of cluster configured with rbd mirror, Master cluster
is production, Backup cluster is DR. Right now all is working good with
Master configured in "tx-only" and Backup in "rx-tx".
I'd like to modify Master direction to rx-tx so I'm already prepared for a
failover after a disaster has happened, but while I'm doin so, I face this
error and i'm stuck:
ceph version 15.2.17 (694d03a6f6c6e9f814446223549caf9a9f60dba0) octopus
(stable)
Ceph user able to operate on Master is rbd-mirror.master, while on Backup
is rbd-mirror.backup
On Master cluster I've my ceph.conf and backup.conf, and on Backup cluster
I've ceph.conf and master.conf
Keyrings has been copied correctly.
I've change direction without any problem, but when i try to configure the
peer with this command, i receive following error:
root@master# rbd mirror pool peer add <my_pool>
client.rbd-mirror.backup@backup
rbd: multiple RX peers are not currently supported
And when I check my pool info, i have the "Client:" section empty (while
the one on my DR is populated with client.rbd-mirror.master"
Can someone lend me a hand?
Is this something I can't do or simply I'm using the wrong commands?
Thanks in advance!

Hi,
maybe you need to remove the peer first before readding it with a
different config? At least that's how I interpret the code [1]. I
haven't tried it myself though, so be careful and maybe test it first
in a test environment.

That's an idea,
moreover I've discovered my two clusters can't be named the same (i.e.
ceph) but I have to change cluster name with environment variable in
/etc/default/ceph (I've deployed ceph via Proxmox 6.x and that's the name
it gives by default to my cluster)
This is kind of an issue cause in red hat ceph it's a simple 3 step
scenario (add CLUSTER variable to the said file, create symlink between
ceph.conf and <new_cluster_name>.conf and you are good to go; unfortunately
in proxmox ceph this doesn't work, instead it breaks every daemon...
If someone has already experienced this scenario and would like to share
his/her experience, I'd be very grateful
