Hey Kevin,
By design, when creating a snapshot, the new volume is created with
'sparse' allocation policy.
I suggest you to open a bug since this operation should not crash the VM.
Add this description and please add all relevant logs and any relevant
information of your environment.
Regards,
Evelina

Hi I have linux VM with 2 disks one for OS is sparse the other is for
a
Database and is Preallocated. When I take a snapshot of the VM both disks
change to sparse policy but the disks in the snapshot are 1 sparse and 1
allocated. Before the snapshot the VM was running fine, now it crashes when
data is written to the database. When I delete the snapshot the disks go
back to 1 sparse and 1 allocated. Has anyone else seen this happen. Ovirt
is 4.3.2.1-1.el7 and it is running on a hostedEngine
Many thanks
Kevin
