[SOLVED] Linked clone feature for 'local:114/vm-114-disk-0.raw' is not available

[Tim Unkrig]

Hi there,

I am figuring out a strange problem and I dont know what else to do.

I have the latest major Version 6.3.3 installed and I would like to make a linked cloned container on a local storage pool. But I get this error message:

Linked clone feature for 'local:114/base-114-disk-0.raw' is not available

Here is my storage settings.cfg:

dir: local
    path /var/lib/vz
    content backup,vztmpl,snippets,iso,images,rootdir
    prune-backups keep-all=1
    shared 1

and the container template config:

arch: amd64
cores: 1
hostname: tmptemp
memory: 512
net0: name=eth0,bridge=vmbr0,firewall=1,hwaddr=DA:6C:AE:A3:EB:FA,type=veth
ostype: ubuntu
rootfs: local:114/base-114-disk-0.raw,size=8G
swap: 512
template: 1
unprivileged: 1

I saw that for VM linked clones "local" storage is suitable, is that NOT the same for lxc container? Or is there anyhing else what I need to consider? I couldn´t find any information about it...

Any help is highly appreciated!

no because on file based storages the qow2 format is necessary to provide linked clones
and containers do not support the qcow2 format

in general you need a storage where snapshots are possible to be able to use linked clones (e.g. zfs/ceph/lvmthin, or file-based with qcow2)

Ok, thank you for the explanation, I went for lvm-thin!
