Please make sureĀ there are no open files inside VE root and/or private area (and your current working directory is not inside VE root/private area) by running the following command on the hardware node:
# lsof 2> /dev/null | egrep '/vz/root/101|/vz/private/101' If there are any processes which hold a directory inside VE root/private area - kill them.
