TASK ERROR: VM is locked (snapshot)

[dison4linux]

Unable to take new snapshots/backups because there seems to be a snapshot in progress.
I've rebooted to the hypervisor, no change.
The snapshots tab shows a 'vzdump' snapshot with a status of 'prepare'

Also...

Hi,

please use:

pct unlock 224

`qm`manages the qemu VMs while `pct` is for containers.

I think that got me a little further, but no joy on a new snapshot yet.

root@hv2:/mnt/pve/nfs-backups/dump# pct unlock 224
root@hv2:/mnt/pve/nfs-backups/dump# lxc-snapshot -L --name 224           
No snapshots
root@hv2:/mnt/pve/nfs-backups/dump# lxc-snapshot --name 224           
lxc-snapshot: lxccontainer.c: do_lxcapi_clone: 2812 error: Original container (224) is running

Using our pct snapshot command works?

pct snapshot 224

Note that the storage where your CT lies needs snapshot support.

It works to create a new one, but not to remove the troublesome one.

root@hv2:/mnt/pve/nfs-backups/dump# pct delsnapshot 224 vzdump

For what it's worth the backup process seems unable to delete the snapshot as well:

If nothing helps, remove it manually from config file. What kind of storage do you use for the container?
