[PVE-User] Empty virtual disk

[Joe Garvey]

Hello all, 

I had to reboot a QEMU based VM yesterday and after rebooting it reported there was no boot disk. The disk has lost all content in the hard drive. There aren't even any partition. I booted the VM with acronis disk recovery and it showed the disk as uninitialized. 

I restored a 6 day old VM and it also had an empty drive. All backups have no data in the drive and are marked as uninitialized. 

I tested restoring other VM's in my environment and they have no issues with the disks. 

The only difference I see is that the drives are smaller. 

The VM in question has been running flawlessly since it was deployed over 30 days ago. 


Proxmox version: 5.4-2 
SCSI controller: VirtIO SCSI 
Disk Size: 200G 
Caching is Disabled 
Storage: Dell NAS server via iSCSI 4x10GB connections (never had a problem with this) 

I'm guessing the data is gone but a ny ideas what has caused this? 

Regards, 
Joe
