Like a normal hard-disk, you will need to format it - currently it is just a 'physical' device (/dev/vdb), you'll need to create a partition table, then a partition, then format that partition to a filesystem. This is not anything specific with oVirt or VM's - just general harddrive management._______________________________________________

Hi,
I'm facing a virtual disk behavior I don't understand.
Currently my VMs are spun up with a Boot disk of 25GB and an additional disk of 215/45/65 GB depending.
When logged to the webui I see the two disks, but when I ssh to VM we only see the primary boot disk, the other one can't get a UUID and then cannot and is not mounted
I also noticed in the webui the second disk doesn't have a logical name as you can see in the screenshot.
Pleas can someone explain this behavior please?
Here is my disk management commands outputs
