Hello guys,

Sorry, I am quite new to Proxmox...

I lost my Proxmox server yesterday and I re-installed it. But the disk with all my VMs are preserved.

Please how can I add this disk safely to my new server. And re-add my VMs

Thank you very much,
 
What type of storage was your disk with the VM images? LVM? ZFS?

If you don't backuped your VMs you only got the disk images and lost all the VM configurations so you would need to create new VMs but you can use the old disk images.

What is the location of the VMs files? I can check if they still there...

I believe it is LVM, but I am not sure about that. The only thing I can see is:

Thank you!!!
 
VM configs were stored on your failed proxmox drive (/etc/pve/qemu-server).

What are fdisk -l /dev/sdb and lsblk /dev/sdb showing?

You got a "lost+found" folder so sdb looks to be just a plain ext4 partition.
You can mount that folder using fstab for example:
nano /etc/fstab
And add a line like...
/dev/sdb /mnt/hdd ext4 defaults,noatime,nodiratime 0 0
...so your partition gets mounted to /mnt/hdd.

Next you need to create new storages for your VMs disk images ("disk image"), backups ("vzdump") and so on Proxmox so it knows where to look for and store stuff.
You can do that using GUI by going to "Datacenter -> Storage -> Add -> Directory" and point it to the folders in that mountpoint.
For example, if your old storage for "disk image" was the folder now mounted in "/mnt/hdd/images" choose that path and select "disk image" as content.
Reboot after that and check if you are able to select a existing disk image for the VM.

You really should considering using raid1 and a external backup storage (USB-HDD, NAS, PBS) so this don't happen again.
