ok, thanks for clarifying.
I thought you meant "proxmox is not a distribution".
What I meant that the installer doesn't include software raid support. But of course it is possible to use software raid (I have done it), but the installer doesn't support it (in fact installation stops) and it is...
Well Dietmar, you should also tell the peope at Distrowach.com about this ;-)

Martin Maurer has announced the release of Proxmox 1.9 "Virtual Environment" edition, a Debian-based distribution designed for running virtual appliances and virtual...
I agree completely :-)
Some people (also from the proxmox team) argue with the "data consistency"/"power off" issue in software raid ("no bbu"). This is true to some extent, but other important tools like vzdump create backups using snapshots which is somewhat like a backup after "power...
Well, I reinstalled everything, and now iotop doesn't work in any container (even one that was not restored). I am not able anymore to run iotop successfully in any container with sl6 (but it works fine on the host).
In other words vzdump/vzrestore work fine and there is no bug at all.
Yes, that is the version I tried. No, idea why I wrote 1.2.3 :-)
Latest entry in the change log was:
2011-05-24 Proxmox Support Team <support@proxmox.com>
* OpenVZ.pm (resume_vm): remove --skiplock flag
Is this is potential bug in vzdump/vzrestore?
Here is what I did:
Install sl6 precreated template from openvz.org
vzctl enter 101
- yum update
- yum install iotop
- exit
vzctl enter 101
- iotop [works fine]
- exit
vzdump --stop --dumpdir /root 101
vzctl destroy 101
vzrestore...
Why does is pre-restart triggered before snapshot and resume_vm (in snapshot mode)?
The order is currently
1. pre-restart
2. snapshot
3. resume_vm (optional)
I expected
1. snapshot
2. pre-restart
3. resume_vm (optional)
Is this a bug?
Ok, will do.
Will try (need to learn about patching first ;-)
Just to make sure I am on the right path. This is basically the only important part in VZDump.pm?
my $mode = $running ? $opts->{mode} : 'stop';
Understand, but if a user uses the option snapshot (and not stop), then it should run in snapshot mode. I think if the user uses the snapshot mode the user aware of the additional disk space requirement.
Would it be possible to add an option for this in the next version (I guess the only...
Just FYI
I downloaded vzdump_2011-06-17 and installed it on Scientific Linux 6.1 x86_64. Then I created a test container using the SL x86 precreated template.
After that I tried
vzdump --suspend --dumpdir /mymount 101
but vzdump failed because of the following error message
INFO: vm is...
Dietmar, thanks. Now I understand 100%
"vzdump snapshot behave like a power loss on physical hardware".
It also answers my question, what happens when a user edits some text with a simple text editor and the system is dumped.
I did search before asking, but didn't find an explicite answer.
The closest one is "http://forum.proxmox.com/threads/2769-Question-about-snapshots?highlight=vzdump". But this was two years ago and the answer was
I also read other topics and used my favorite search engine, but still not sure...
Even though I read a lot about it, I am still not sure. May be you know more :-)
I know that it is possible to create snapshots of a running container. But I am wondering whether this operation is "safe". For example no matter what complex database and memory "stuff" is running in the...
The proxmox distribution only supports hardware raid. It is probably not worth the effort for the developers to integrate software raid in their installer. Data integrity is only a secondary reason (otherwise they wouldn't allow installation on systems without any RAID at all ;-)
Your option is...
Haven't tried it yet (still waiting for proxmox 2.0 and hopefully doesn't take as long as centos :-)
But the guide looks great and I appreciate it! Thanks1
