I have a node with 2 CTs.
- CT 136
CentOS 5.2 (template centos-5-i386-default-5.2-20090117)
using 1.8G.
- CT 143
CentOS 4.7 (template centos-4-i386-minimal-4.7-20090117)
using 2.7G.
When I make a vzdump --snapshot --dumpdir /home/backup --all
it runs without an error and creates 2 tar files:
vzdump-136.tar (1.5G) and vzdump-143.tar (10K).
This is the log file vzdump-136.log:

This is the log file vzdump-143.log:
Feb 12 09:14:17 INFO: starting backup for VPS 143 (/var/lib/vz/private/143)

Feb 12 09:14:18 INFO: backup for VPS 143 finished successful (0.02 minutes)
Questions:
Why does vzdump create only a tarball of 10K for CT 143?
Does snapshot not work with CentOS 4 CTs?
My Node is an Ubuntu 8.04.1 server with kernel 2.6.24-23-openvz SMP on a 8GB RAM machine with an AMD Athlon 64 X2 5400+ CPU.
