LVM storage, logical volumes are not removed

[mmenaz]

Hi, I'm using LVM storage, when I create a VM and add an hard disk to that storage, everything is ok, but when I remove it, the VM config is updated but the logical volume is not deleted, so I've exausted my space
I'm using pvetest repo
I.e. I've created vm 301, 302 and 303. I wanted do add 3 more (4 total) HD to each of them, but when I was in 303 I was unable because of no more free space in the LVM storage. Ok, I removed the 4° HD from 301 and 302, but still was unable to add, this time 2 more hd, to 303.
This is the situation:

I'll remove the logical volume manually but would love this bug be investigated and fixed
