Hi,

It is located on NFS storage domain V4.

Note that there is a bug that will prevent you from creating a VM from a template as with preallocated disks - https://bugzilla.redhat.com/show_bug.cgi?id=1403183

This was fixed only in version 4.3

Furthermore, it seems that fix missed the scenario you described.

Can you please submit a bug and attach the VDSM and the engine logs?

Is your disk is based on a file storage domain?

Hi !

Followup to my previous post.
Creating template from snapshot in 4.2.8 also suffers from the same bug - allocation policy selected to thin provision even if I select RAW from the popup menu.
Verified twice.
