We don't have a way to start rbd-mirror using vstart script right now, but that would be good to have I guess.
Yes, rbd-mirror in case of multicluster
bin/rbd-mirror --mon_host $mon_host_for_site_b --key $key
where key could be fetched using :
../src/mrun site-b ceph auth get client.admin

Thank you! This worked perfectly. Also If I want the rbd-mirror daemon to be running, I'll need to start the daemon like rbd-mirror -d right? Is there any other way we can do that? I mean like providing an arg like RBD-MIRROR=1 as the vstart args.On Mon, Jun 27, 2022 at 12:19 PM Deepika Upadhyay <dupadhya@xxxxxxxxxx> wrote:sure, the command could be written as:../src/mrun $cluster_name dashboard set-rgw-credentialsOn Mon, Jun 27, 2022 at 12:13 PM Nizamudeen A <nia@xxxxxxxxxx> wrote:Thank you so much Deepika..

But I ran into this issue when I am issuing any ceph commands like we do for the vstart clusters. I am not sure how to run the ceph commands here. Does any one use mstart clusters here for multi-cluster development?Also It would be great to know which is the easiest way to start a multi-cluster dev environment within the same machine, if I want to play around with rbd-mirroring.Thanks in advance.
