Looking to restore this LXC.

Version 6.4-13

backup job for LXC failed config file deleted after the BU failed but is still showing in the GUI as Container 104 (SMB) on node 'Vader' (snapshot-delete) "see attachment"

Showing that the container is locked and tried to start the container and it came back with status output:
TASK ERROR: CT is locked (snapshot-delete)

Tried to unlock to CT
root@Vader:/etc/pve/lxc# qm unlock 104
Configuration file 'nodes/Vader/qemu-server/104.conf' does not exist


Checked in /etc/pve/lxc and see the 104.conf file
root@Vader:/etc/pve/lxc# ls -al
total 2
drwxr-xr-x 2 root www-data 0 Apr 4 2021 .
drwxr-xr-x 2 root www-data 0 Apr 4 2021 ..

Checked in /etc/pve/qemu-server and the 104.conf file is missing

checked in the /var/lib/vz/dump/ and the vzdump-lxc for 104 is not there.


Any suggestions would help!

Thanks

The good news after some digging I have found all of my data located in /NAS-Local/subvol-104-disk-0/ dir. Just looking for info on how to restore the LXC so it can boot.

Thanks in advance,
