Good morning
I have a doubt, when i do a snapshot, a new lvm is generated, however when I delete this snapshot the lvm not off, that's right?
You question is not clear. Can you explain what is the unexpected behavior?
To check if an lv created or removed by ovirt, you can do:
pvscan --cache lvs vg-uuid
