After snapshot backup of running VM (KVM+LVM) VM is left locked; in /etc/pve/qemu-server/<VMID>.conf we see

[PENDING]
lock: backup
​

Executing

qm unlock <VMID>
​

does not remove lock (this cmd is called in QemuServer.pm > unlock_vm so maybe there is something broken in qm unlock?).

Thanks for the bug report - will try to fix asap.

I just uploaded the fix. Please can you update and test if it works now?

 

[ib.pl]

Updaded package resolved the issue - snapshot backup of running KVM/LVM machine does not leave lock now.

Thank you for help!
