[ovirt-users] ovirt vm disk space not release

[smiling dream]

Thanks for you reply .
So if I understand you correctly you want to reduce the space a thin
provision disk takes up on the NFS share because you deleted files within
the VM?
Yes

Is there any others way to reclaim disk space , coz i have bulks of vm
under thin provision manual process kind of impossible . As i know Vmware
have this kind of facility to reclaim from thin provision .
