[SOLVED] LXC Container on ZFS Volume

[MasterTH]

Hi,

i tried to create an lxc on a zfs-pool.

this is what i get as an error:

Please create a ZFS storage on the Datacenter/Storage GUI first. (I suggest you create a zfs subvolume
for the VM data first).

getting this now:

mount: special device /rpool/ROOT/pve-1/subvol-100-disk-1 does not exist
mounting container failed
TASK ERROR: command 'mount -o bind -o '' /rpool/ROOT/pve-1/subvol-100-disk-1 /var/lib/lxc/100/rootfs/' failed: exit code 32

The driver expects the volume to be mounted on the standard mount point - that is why I suggested that
you want to create a subvolume first (which is mounted at /rpool/yoursubvolume/).

ah... thats the trick.

thanks
