Hi, It doesn't seem to do anything if the container is running:
[root@sovereign ~]# du -sch /vz/private/101/root.hdd/ 114G /vz/private/101/root.hdd/ [root@sovereign ~]# vzctl exec 101 df -h / Filesystem Size Used Avail Use% Mounted on /dev/ploop42957p1 277G 101G 162G 39% / [root@sovereign ~]# /usr/sbin/pcompact ...
