## Enabling disk UUID in proxmox VMs
The configuration file for each VM has to be edited, so that the disk comes with a unique serial number
1. `vi /etc/pve/qemu-server/<VMID>.conf`
2. Add a unique serial number to the disk
```
scsi1: images:<disk image>,cache=writeback,discard=on,size=120G,ssd=1,serial=5fb20ba17c2f
```
3. Restart the VM
`qm shutdown <VMID> && qm start <VMID>`

This will assign the unique serial number to the scsi disk. Even though WWN is absent OpenEBS will be able to
identify the disk using the unique serial number.
