It seems that the issue is within the 'dd' command as it stays waiting for input:

Changing the dd command works and shows that the gluster is working:
[root@ovirt1 mnt]# cat /dev/urandom | /usr/bin/dd of=file oflag=direct,seek_bytes

Тема: ovirt 4.3.3.7 cannot create a gluster storage domain
Hey guys,
I have recently updated (yesterday) my platform to latest available (v4.3.3.7) and
upgraded to gluster v6.1 .The setup is hyperconverged 3 node cluster with ovirt1/gluster1
& ovirt2/gluster2 as replica nodes (glusterX is for gluster communication) while
ovirt3 is the arbiter.
Today I have tried to add new domain storages but they fail with the following:

It seems that the 'dd' is having trouble checking the new gluster volume.
The output is from the RC1 , but as you see Darell's situation is maybe the same.On

4.3.3.7 and gluster 6.1. I was able to create the new gluster volume fine, but it’s not
able to add the gluster storage domain (as either a managed gluster volume or directly
entering values). The created gluster volume mounts and looks fine from the CLI. Errors in
