G'day,

I've reinstalled Proxmox on my server, and am having trouble adding my existing LVM storage to a container.

fdisk -l

Code: 
Disk /dev/mapper/Media-vm--100--disk--0: 7.6 TiB, 8311982260224 bytes, 16234340352 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

my current container config

Code:

hostname: Emby
memory: 16000
mp0: /dev/Media/vm-100-disk-0,mp=/srv

ostype: ubuntu
rootfs: local-lvm:vm-100-disk-0,size=20G

the error I receive when I attempt to start the VM is as follows:

I have tried mounting from /dev/mapper /dev/Media.

I did notice that I get the error wrong fs type etc. Any help would be appreciated.
