Hello,
I have a problem again.
I try to rsync my server to back it up(via snapshot).
The prog uses this cmd to do so:
/usr/bin/rsync -azHx --delete --numeric-ids --relative --delete-excluded --stats --rsh="/usr/bin/ssh -c blowfish" root@ip.here:/ /var/cache/rsnapshot/hourly.0/myserver/
Looks good. On the one vz it works good. The other one crashes. I cant login via ssh or so. via vzctl I can enter. But I have to restart the vz to get it back to work.
This is the user_beancounters for the box that works:

1. what do you mean by snapshot? LVM snapshot or what? rsync doesn't do any real(!) snapshots.
|
The program is namend rsnapshot ( http://www.rsnapshot.org/ ). Its something that generates rsync cmds and moves the old files away. Nothing special.
| Quote: |
2. Do I understand correctly that you run this command from inside VE to backup its data *to* remote server?
|
oke, my fault. The setup:
fileserver (for the backup)
box with openvz-kernel
-->virtual box 1 (works with the rsnapshot/rsync)
-->virtual box 2 (does not work with rsnapshot/rsync)
the fileserve runs the rsync cmd.
| Quote: |
2. What do you mean by crashes?
Does your host system continues to work?
Can you ssh to the host?
Do you see some kernel messages on the screen?
|
After some MB of the rsync, rsync dies. So it does not copy eny more files.
I _can_ ping the virtual box.
I _cant_ ssh the virtual box.
I _cant_ ping from inside of the virtual box.

3. is it reproducable? if yes, can you demonstrate it with exact commands/details and maybe provide us login to resolve it?
|
The good news: It is reproducable. And it is simple. I simply run this cmd from the fileserver: rsync -rv root@ip.of.virtual.box.2.:/ .
Give you access: May be possible. The problem is that this box runs a memberdatabase of two NGOs. Perhaps we will find a way to do this via screen, hm?
| Quote: |
4. what are kernel versions on source and destination nodes (uname -a)? have you taken kernels from binary RPMs or rebuilt kernel yourself? what kernel configs have you used?
|
uame -a:
Linux bi-o-mass 2.6.9-023stab032.1-ovz-i386 #1 Thu Oct 26 19:39:19 UTC 2006 i686 GNU/Linux
The kernel is from debian testing. I used the binary build of the guys.

Ok, this makes me believe that host system continues to work, right?
But VE networking somehow stops responding?
Does ping ve-ip-addr wo]rks?
Do you mean "restart vz" == "/etc/init.d/vz restart"? If yes, I guess 'vzctl restart VEID' helps as well?
|
I restart the machine via vzctl restart VZID. VZ seems running fine as well as the other virtual systems. Normaly it takes ~10 sec to restart this virtual server(2). But in case of doing an rsync before it takes ~60 sec.
I dont find any output in any logfiles. If I have time at the weekend I will drive to the serverroom and look at the screenoutput.

P.S. I renamed the title of your post, since it was too emotional, with too incomplete information.

No probem. It was just a funny idea 
Thanks for your time!
