[pve-devel] [PATCH guest-common 3/3] fix #6808: abstract config: snapshot delete: improve error when snapshot on volume is missing

[Fiona Ebner]

In case of a ZFS volume the message would be a rather unhelpful:
> zfs error: could not find any snapshots to destroy; check snapshot names.

Mention the volume name and that the force parameter can be used if
desired.
