[PVE-User] Conversion LXC -> VM, mountpoint to volume?

[PVE-User] Conversion LXC -> VM, mountpoint to volume?

[Marco Gaiarin]

In my home server i've an LXC container with an additional mountpoint, that
contain a lot of data (1.5TB).

I need to convert the LXC to a VM; there's no trouble to reinstall the base
machine, but if possible i don't want to 'move' 1.5TB of data...


Can i simply (a rename suffices? I'm using ZFS as storage) convert an LXC
mountpoint to an VM (additional) volume?


Thanks.

Hi,
I don't think that's possible without moving the data. The LXC 
mountpoint is a ZFS file system, but for a VM you need a ZFS volume, 
which is a virtual block device, so renaming won't work.

 root@vmedialpb:~# mount | grep /srv
 hddpool/data/subvol-102-disk-0 on /srv type zfs (rw,xattr,posixacl)

OK, i have to move some data... ;-(((


Thanks.

in theory, there is a way to passtrough files into a VM in kvm/qemu, but i don't think thats "ready for production", especially with large amounts of data
