Excessive usage Storage Domain: Actual VS Virtual size of VM
Issue
Live snapshot deletion was causing actual disk size to grow and never redeemed even after snapshot deletion. This cause waste of space for no reason.
Nominally we should have a usage of 1355 Gb Virtual Size while in reality we have an Actual Size of 3979Gb .
A support procedure is needed to reduce the Actual Size of those VM and a way to avoid it happen.
