<br>
Not sure if it's a bug or a limitation but, while playing with oVirt 4.1 new possibilities, I tried to use the sparsity function on a preallocated disk, and this action irreversibly ruined the data on the disk. I have repeated this experiment multiple times and always same result. (Sparsifying a thin provisioned disk works great though)<br>
<br>
I understand that the "sparsify" function is relevant to thin provision disks only. Still I think there should be a warning before doing this action on a preallocated disk? or maybe even forbid this action on a preallocated disk since sparsify has no meaning on a preallocated disk? (I maybe wrong...)<br>
<br>
thanks<br>
