    [TUTORIAL] Proxmox Ceph Mirroring - Snapshot Mode

    Like i said in some of my previous posts i have tried ceph mirroring before, and followed the instructions available here. This worked great, but only if you just used virtual machines, and not containers. So this does not work with container disks, because you would need to enable the...

    Can this be used with the ceph pools used by a proxmox ve server ?

    I have a proxmox ve cluster, configured with ceph. Could i install this as a vm on another cluster and have it use the ceph cluster on the first cluster i mentioned ? Im thinking that would mean being able to add a ceph datastore on the backup server.
