[lxc-users] Cannot remove a volume that has snapshots

[Kees Bakker]

Hi,

When I want to delete a container I'm getting this error

root at ijssel:~# lxc delete jenkins
Error: Error deleting storage volume: Cannot remove a volume that has snapshots

However, it has no snapshots.

root at ijssel:~# lxc info jenkins
Name: jenkins
Location: ijssel
Remote: unix://
Architecture: x86_64
Created: 2020/04/24 09:01 UTC
Status: Stopped
Type: container
Profiles: default

This is on Ubuntu 20.04 with lxd 4.0.1 (14954) from snap.
The storage is lvm.

There is a little bit of history that is of interest.
I had a container, "jenkins-template", with a snapshot.
Then I did a "lxc copy" of that snapshot to a new container,
called "jenkins", the one that I'm trying to delete now.
In the meantime I have already deleted the snapshot of "jenkins-template",
because I thought that would help.
Now, there are no snapshots at all on the system. Still, the
delete gives me that error.
