But if I try creating new disk image from the oVirt GUI - I get
preallocated volume. No matter if I select "thin provision" or
"Preallocated" I always get preallocated volume created.
The engine.log says -
2019-05-07 17:14:20,562-04 INFO

Is there any tweak I didn't notice to make things actually what
it suppose
to be doing?
oVirt 4.3.3.5-1.el7
glusterfs 5.5-1.el7
CentOS Linux release 7.6.1810
Thank you!
It seems this is the third separate thread regarding the same problem since
25/04 but I have not seen any answer (positive or negative) from one of the
oVirt developers / maintainers yet on the list...
(perhaps right now probably involved in Red Hat Summit.. )
Anyway I see that Strahil already opened a bug here:
https://bugzilla.redhat.com/show_bug.cgi?id=1704782
And there is useful information inside it, such as that the problem is only
on gluster and only if disk is created from webadmin GUI, while from rest
API is ok.
Also from 4.2 to 4.3 disk format (only on gluster) changed default from
thin provisioned to preallocated.
Hih,
