Backup live

[Maxence]

Hello,

Is it possible to backup a vm in live (mean without to shutdown the vm)
I added a storage, created a backup job. snapshot doesn't work if my vm isn't shutdown.

Jan 16 14:27:01 cron26937 (root) CMD (vzdump --quiet --node 1 --snapshot --storage NFS-Backup1 --mailto my@mail.com 108)
Jan 16 14:27:01 vzdump26937 INFO: starting new backup job: vzdump --quiet --node 1 --snapshot --storage NFS-Backup1 --mailto my@mail.com 108
Jan 16 14:27:01 vzdump26937 INFO: Starting Backup of VM 108 (openvz)
Jan 16 14:34:03 vzdump26937 ERROR: Backup of VM 108 failed - command 'rsync --stats -x --numeric-ids --bwlimit=10240 -aH --delete --no-whole-file --inplace '/var/lib/vz/private/108/' '/mnt/pve/NFS-Backup1/vzdump-openvz-108-2010_01_16-14_27_01.tmp'' failed with exit code 23

My storage is empty

But When I shutdown my vm

Jan 16 14:40:51 pvedaemon28479 VM 108 stopped

The rsync manual page says "error 23 Partial transfer due to error".

What kinf of NFS server is that?

 

[Maxence]

I test openfiler for now

 

[dietmar]

And the error is reproducable?

 

[Maxence]

Yes, I just need to backup a vm online

 

[dietmar]

OK, will try to reproduce the bug here - what openfiler version do you use?

 

[Maxence]

I'm using Openfiler NSA 2.3

 

[tom]

I'm using Openfiler NSA 2.3

I just tested here with the latest openfiler 2.3, works as expected.

what Proxmox VE version do you use (update to the latest) and post the output of:

pveversion -v

and

vgs

 

[Maxence]

Ok :

root@mengy:~# pveversion -v
pve-manager: 1.4-10 (pve-manager/1.4/4403)

[tom]

Ok :

there is no free space in the vg (only 4,00M).

a standard ISO install has 4.00G.

 

[Maxence]

Here is my parition disk

1 primaire ext3 / - 20000 Mo
2 primaire swap swap - 1024 Mo
3 LV ext3 /var/lib/vz - 478976 Mo

How it's possible ?

 

[dietmar]

How it's possible ?

How did you install that system?

You need free space on the volume group (not on the locial volumes).

 

[Maxence]

From OVH, we can install directly proxmox 1.5 + openVZ + kernel 2.6.x-pve on debian 64bit. And I use default partition.

From OVH, we can install directly proxmox 1.5 + openVZ + kernel 2.6.x-pve on debian 64bit. And I use default partition.

No, OVH installs currently 1.4, not 1.5. For OVH specific questions best place to ask is OVH.

Take a look on the LVM documentation, its a bit of work but its possible to change the partitioning that you can use LVM snapshots.

 

[Maxence]

It's 1.5, I tested yesterday and they announced it on the ml.

I'll see for LVM documentation.

Thanks
