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:
Feb 12 09:11:03 INFO: starting backup for VPS 136 (/vz/private/136)
Feb 12 09:11:03 INFO: creating lvm snapshot of /dev/mapper/system-vz ('/dev/system/vzsnap')

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 09:14:17 INFO: creating lvm snapshot of /dev/mapper/system-vz ('/dev/system/vzsnap')

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.

Hello!
Centos 5.2,
kernel 2.6.18-92.1.18.el5.028stab060.2,
vzctl version 3.0.23
vzdump version 1.1.1 (also try 1.0.2)
When I run a vzdump e.g:
vzdump --suspend --dumpdir /var/local/backup/vps --compress 2534
It creates a 10K tarball with vps.conf only;
INFO: starting backup for VPS 2534 (/vz/root/2534/private)
INFO: starting first sync /vz/root/2534/private to /var/local/backup/vps/tmp21304
INFO: suspend vps
INFO: Setting up checkpoint...
INFO: suspend...
INFO: get context...
INFO: Checkpointing completed succesfully
INFO: final sync /vz/root/2534/private to /var/local/backup/vps/tmp21304
INFO: resume vps
INFO: Resuming...
INFO: vps is online again after 6 seconds
INFO: Creating archive '/var/local/backup/vps/vzdump-2534.tgz' (/var/local/backup/vps/tmp21304/2534)
INFO: :Totally 10240 (10KiB, 4,1MiB/s)
INFO: backup for VPS 2534 finished successful (1.68 minutes)
Is anybody solve this problem? Thank you!
