Searching for advices for a migration

[proxnano]

Hello guys,

At the moment my proxmox is installed on 4x 146Go but its not enough to store all VMs i need. I have installed 4 more HDD but since i can't add HDD to my logical volume, i'll need to wipe my disks and create a new logical volume with my 8 HDD.

I have found how to migrate VMs from a proxmox to another or how to backup VMs but i haven't found how to backup my proxmox configurations (backup network dns...) to restore them for a fresh install

You're using LVM right now? Why should it not be possible to extend your volume group to the newly added disks?

That's a good question, i've never extend a volume using LVM. I think that this can solve my space problem but before i try that it would be good to do a backup of my proxmox and i don't know how to do that

Yes, Backup is always good, but extending LVM is easy as pie in Linux:

• add your disks as a new raid group or whatever you've done with the other disks
• create physical volume(s)
• extend volume group with physical volume(s)
