Run container from physical root disk

LXD
1

Hi,

I have situation where I’d like to run an lxc container with a physical block device for it’s root.

I saw a similar question here, although it’s for VMs: Override root device for VMs?

I did try a variation on that, but want to still leverage a local lxc image. So, I created the container using the normal pool [ which is zfs ], added the extra disk with boot priority, then synced the data from the mounted zfs volume to the mounted block device partition [ formatted with ext4 ], then tried to start the lxc conatiner. But I get an error on start.

No such file or directory - Failed to mount "/var/snap/lxd/common/lxd/devices/test-container/disk.local--disk." on "/var/snap/lxd/common/lxc//none"

[ sorry, I know it’s lxd, but I’m stuck on that for now, and hoping for some help still ].

The devises section looks like this:

devices:
  local-disk:
    boot.priority: "10"
    source: /dev/sdb1
    type: disk

Is what I’m attempting here even achievable ?

Thanks!

Cheers,
Just
