Partition completely lost volume

[fpetrutiu]

Hello there,

I am using Proxmox 5.1.-35

On one of my VM's running Windows 2012 R2 that has 2 disks: local-lvm:vm-200-disk-1 size=100G and local-lvm:vm-200-disk-2 size=300G the first disk l (local-lvm:vm-200-disk-1) seems to have completely blanked itself. In other words, I can see the disk with Windows 2012 R2 command prompt's DISKPART, however it is showing that the disk is 100GB with 100Gb free.

Further, when I look at volumes and partitions on that disk, none exist.

I see the disk in /dev/pve as vm-200-disk-1

I have tried several times to start and restart the VM but to no avail. That disk seems to have disappeared.

This looks like a guest OS problem: The disk is still there, your OS disappeared. What have you done in Windows that the disks is blanked? Reset your Partition table?

Nothing at all.Server was working then crashed (the memory issue, blue screen). Then when I rebooted, the partition table is gone.
I tried rebuilding it, the MBR, every other trick in the book to no avail.

, every other trick in the book to no avail.

So you tried testdisk already?
