Info on disk:

[g.cecchi at ovmsrv07 ~]$ sudo qemu-img info
/rhev/data-center/588237b8-0031-02f6-035d-000000000136/900b1853-e192-4661-a0f9-7c7c396f6f49/images/f0b5a0e4-ee5d-44a7-ba07-08285791368a/7ed43974-1039-4a68-a8b3-321e7594fe4c

file format: qcow2
virtual size: 430G (461708984320 bytes)
disk size: 0

Based on another command I learnt from another thread, this is what I get
if I check the disk:

[g.cecchi at ovmsrv07 ~]$ sudo qemu-img check
/rhev/data-center/588237b8-0031-02f6-035d-000000000136/900b1853-e192-4661-a0f9-7c7c396f6f49/images/f0b5a0e4-ee5d-44a7-ba07-08285791368a/7ed43974-1039-4a68-a8b3-321e7594fe4c
Leaked cluster 4013995 refcount=1 reference=0
Leaked cluster 4013996 refcount=1 reference=0
Leaked cluster 4013997 refcount=1 reference=0

... many lines of this type ...

Leaked cluster 6275183 refcount=1 reference=0
Leaked cluster 6275184 refcount=1 reference=0
Leaked cluster 6275185 refcount=1 reference=0

57506 leaked clusters were found on the image.
This means waste of disk space, but no harm to data.
6599964/7045120 = 93.68% allocated, 6.30% fragmented, 0.00% compressed
clusters
Image end offset: 436986380288

Can it help in any way to shutdown the VM to unlock the disk?

Thanks,
Gianluca
