At this moment, for version mentioned below, this bug is actual?
Yes, libvirt does not support multiple hosts for gluster disk yet.
A workaround may be using DNS address that expose all hosts.
Nir
comment 13 at 2018-08-31 asks for workaround is unanswered too..
more than a year has passed since that, versions updated
now qemu-kvm-ev-2.10.0-21.el7_5.7.1.x86_64
vdsm-4.20.43-1.el7.x86_64
glusterfs-server-3.12.15-1.el7.x86_64
I cannot reproduce it on my test install because I not configured
storage fully (see my "set up ovirt 4.2 hyperconverged with glusterfs
"storage network" over infiniband" post here)
But if it needs I may try.
