Hi Yannis! Thanks for the quick answer... Yes, on my PVE Server I have 3 virtual machines and I want to recover them in another Server in cause of hardware failure...
So, I just have to mount that LUN partition in another Server right? Is it easy to recover the backup? Can I restore the backups over web interface or should it go over shell console? Well, for now it's just a small lab, my plan is make it bigger! Any other trick or advise for me in what regards recovery disaster?

It's available on Galaxy: htt ps://galaxy.ansible.com/lae/proxmox/. The main features currently are IPMI watchdog configuration and SSH key generation/configuration (with the assumption that root logins are disabled by default, as they should be). It doesn't perform the cluster creation step (yet) - but all that's needed after applying the role are running `pvecm create $clustername` on $firsthost and `pvecm add $firsthost` on the remaining hosts. So far I've used it to deploy 4.3 and 4.4 clusters without issue, and I've also used it to upgrade a 4.3 cluster to 4.4 (without automatic reboot). I'm open to contributions and/or suggestions, so feel free! lae / Musee ------------------------------ Message: 2 Date: Thu, 26 Jan 2017 00:08:49 +0000 From: Leonardo Dourado <[email protected]> To: "[email protected]" <[email protected]> Subject: [PVE-User] Recovery Disaster - What is the best practice...?

Can someone please advise what is the best procedure in case of recovery disaster? My scenario is: I have a PVE Server running a few machines, I also have a NAS with some disks... I wanna point to that NAS the backup of these machines (in a way I can recover them in another server in case of hardware failure). I see on PVE the Backup service, I am not sure if I have to recover a whole VM to another server that is the proper service, it looks too simple (mostly snapshots). My plan is have Proxmox as a main server for VMs so, I have to think about "if my hardware fails", what can I do to move the machines to another server... Much appreciated, Leonardo D. ------------------------------ Message: 3 Date: Thu, 26 Jan 2017 11:54:31 +0300 From: jatani halake <[email protected]> To: [email protected] Subject: Re: [PVE-User] pve-user Digest, Vol 106, Issue 24 Message-ID: <CAJ=q44fcq7zduyksbpvc3e0uvgpziz59tqvddr13chnc+bd...@mail.gmail.com> Content-Type: text/plain; charset=UTF-8 after i mount my recovered vm disk which is vm-902-disk-1.raw, how can i recover my data by using testdisk? when i mount on some directory it only contains lost+found, So plz any help!

Message-ID: <cafif2ooo7ouoxivemhmjq4xwxdgx62s160ccygv0i1f3xph...@mail.gmail.com> Content-Type: text/plain; charset=UTF-8 Your question is quite generic because it depends how you have configured your PVE, what will be the storage backends etc. I will assume that you have one PVE server with VMs stored in a local storage like LVM or ZFS. You have a NAS as well where you store the backups of these VMs (full backups).NAS is configured on PVE as a NFS target. So if your PVE server dies, the only thing needed is to mount NAS as NFS target on the new PVE server and just retore the backups there. That could take some time depending on the size of VMs. Yannis On Thu, 26 Jan 2017 at 00:09, Leonardo Dourado < [email protected]> wrote: > Hi All! > > Can someone please advise what is the best procedure in case of > recovery disaster? > > My scenario is: > I have a PVE Server running a few machines, I also have a NAS with > some disks...
