How to Transfer .raw files to restore VM on other server?

[altomarketing]

Hi ! i have a server with some problems and all my 10 VM are stopped, and i dont have .conf files of those VMs

How can i transfer the .raw files to other proxmox and rebuild VM again ? - I can not do a backup in the old server.

Just copy the files via scp. If you setup Proxmox VE with 4.x with x >=2, then you have thin-lvm and have to create a "real" volume first:

e.g.
http://pve.proxmox.com/wiki/Install....2Fvar.2Flib.2Fvz_.28Proxmox_4.2_and_later.29

or

http://pve.proxmox.com/wiki/LVM2#Create_a_extra_LV_for_.2Fvar.2Flib.2Fvz

If you setup Proxmox VE with 4.x

Its from 4.x to 4.x , but what after migrating the .raw files via scp, how to restore them ? via command line or gui ? how to do it ?

 

[LnxBil]

Create dir real volume and mount it as I described earlier and then just import using the already available documentation:

http://pve.proxmox.com/wiki/Migrati...ws_physical_machine_to_a_VM_raw_file_directly

It's like a migration, because you do not have anything left from you configuration as you claim.

Good !!

but up to the wiki : Once this completes you can assign this disk file to your VM on the Proxmox interface.

What do you mean by assign the disk file ? as template ?

by restore the the raw file i can not do it.

 

[LnxBil]

you need to create a new VM with a raw disk the same size as the one you used and then scp the file from the other server "over" this file.

scp the file from the other server "over" this file.

Perfect !!, but i can not find where is the new .raw file , im on pve 4.3

1. what is dm-6 ?
   
2. where should be find the vm-100-disk-1 file to replace ?
3. what about hwaddr ? what should i modify it ?

Thanks in advance.

I also have the problem that when I do a scp inside the new server , i pull into /dev/pve , but i get udev fulled..

Filesystem     1K-blocks    Used Available Use% Mounted on
udev               10240   10240         0 100% /dev

so my newby questions are:

1. what is dm-6 ?
   
2. where should i pull with scp the raw file ?
   
3. where should be find the vm-100-disk-1 file to replace ?
4. what about hwaddr ? what should i modify it ?

1) dm stands for device mapper and the name does not matter now.
2) To e.g. /tmp and then dd to your lvm volume (because you created a volume for that. Seams that you do not have considered my previous answer in #2).
3) It's stated in your output: /dev/pve/vm-100-disk-1 - this is a block file, not a regular one, so you need to dd as mentioned in 2
4) If you do not run both machines at the same time, no.

I strongly suggest never to use RAW files and do backups regularly.
