[ovirt-users] Storage slowly expanding

Hi all: I have several VMs, all thin provisioned, on my small storage (self-hosted gluster / hyperconverged cluster). I'm now noticing that some of my VMs (espicially my only Windows VM) are using even MORE disk space than the blank it was allocated. Example: windows VM: virtual size created at creation: 30GB (thin provisioned). Actual disk space in use: 19GB. According to the storage -> Disks tab, its currently using 39GB. How do I get that down? I have two other VMs that are somewhat heavy DB load (Zabbix and Unifi); both of those are also larger than their created max size despite disk in machine not being fully utilized. None of these have snapshots. How do I fix this? Thanks! --Jim
