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! Elia
