VPS

VPS is locked when some operation (backup, migration, start / stop, etc.) with this VPS is in progress. You can determine which process is holding VPS #101 using the following command on the hardware node:

# cat /vz/lock/101.lck

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.
