[ovirt-users] can not use iscsi storage type on ovirt andGlusterfs hyper-converged environment

[Maor Lipchuk]

Thanks for the logs,

What kind of VDSM version are you using?
    "rpm -q vdsm"
There seems to be a similar issue which was reported recently in the VDSM
area
(see https://bugzilla.redhat.com/show_bug.cgi?id=1197292)
It should be fixed in later versions of VDSM vdsm-4.16.12-2.el7ev.x86_64
Adding also Nir and Jeff to the thread, if they have any insights

Regards,
Maor
