    We want to run backup of CephFS with erasure coded backed pool at k=10 m=2, but we couldn't get this to mount on our proxmox ve 5.3

    Also, being able to create EC RBD pools would be great where we are running with k=2 m=1, which has faster reads at low disk cost than replica=3

    [Fixed] the ceph fs part with ec coded pool on external ceph.


    Additionally, for the rbd we shouldn't have to specify --data on every single image creation. I hope proxmox by default doesn't do it as the pool being used is the default rbd pool regardless of the following setting in my ceph.conf which is followed by openstack.

    [client.admin]
    rbd default data pool = rbd-ec112

    This should ideally work as it does with openstack. Any reason proxmox doesn't respect this rule?
