After a recent Proxmox update, my LXC container (ID 109, running Plex) fails to start. I attempted to restore from a backup, but the issue persists. Below are the debug logs:

Code: 
lxc-start: 109: ../src/lxc/sync.c: sync_wait: 34 An error occurred in another process (expected sequence number 7)
lxc-start: 109: ../src/lxc/start.c: __lxc_start: 2114 Failed to spawn container "109"

Any assistance or suggestions to resolve this issue would be appreciated. The problem persists even after restoring the container from a backup.
 
I general I can say there is no lxc start problem on pve 8.3.3 with kernel 6.8.12-7 and 6.8.12-8 when migrating lxc on cluster hosts.
Try "pct start 109" in pve host console which may give further/better error message as when started be webui.

Inappropriate ioctl for device --> First outcommend your mp0 line in the lxc 109.conf file and try to start the VM with pct start 109 again "solo".
If that does *NOT* work have an empty dir on pve host, maybe /net, and "mount -o loop </path/to/vm-109-disk-0> /net" (/dev/pve/vm-109-disk-0 ?),
does it mount and is shown by "df" ?

Still the same and yes it mount ..
 
Create new LXC and copy your data from loop mounted LXC to new LXC, then use your new LXC again with your mp0 line.
When all fine remove LXC 109.
