Any operation on a VE gives me “Cannot lock VE”.

Any operation on a VE gives me “Cannot lock VE“.

VE is locked when some operation (backup, migration, start / stop, etc.) with this VE is in progress. You can determine which process is holding VE #111 using the following command on the hardware node:

# cat /vz/lock/111.lck

16824
backing-up

You can kill that process if needed. Make sure that the process is really killed. If there is no process with that PID on the node, just remove the lockfile.

# kill 16824

# vzctl start 111
