I have a VM with logical volume based disk, which for some reason does not indicate its size, even though when i created the VM using the "create empty instance" I indicated 20GB for the "Disk space allocated to instance". it is marked for backup but in the backup log it indicates it is excluded, when I tried to toggle the backup on and off it reports:
Failed to save disk : Missing or invalid disk size
Now in the past I have learned that setting this value can scramble the drive, so I need to know an approach to setting this correctly, as I dont have a backup and need it to back up with all the others.
The volume on the host is set at 20 GB. I think this might be a bug in the "Create Empty System" process, so while we try to sort out my VM, I will do some tests and see if I cant replicate the missing size problem.
