[lxc-devel] lxc-clone and lvm snapshot problem

[Serge Hallyn]

Quoting KATOH Yasufumi (karma at jazz.email.ne.jp):
> When backing store is LVM (without thinpool), lxc-clone can use snapshot(-s).
> 
> # lxc-create -B lvm -n c1 -t download
> # lxc-clone -s -B lvm -o c1 -n c2
> # lvs
>   LV   VG   Attr     LSize Pool Origin Data%  Move Log Copy%  Convert
>   c1   lxc  owi-a-s- 1.00g
>   c2   lxc  swi-a-s- 1.00g      c1       0.01
> 
> Then if we run "lxc-destroy -n c1", it deletes not only LV:c1 but also LV:c2.
> 
> # lxc-destroy -n c1
>   Logical volume "c2" successfully removed
>   Logical volume "c1" successfully removed
