Thank you all for the nice hints.
Somehow my host was not able to access the userspace RDMA, after
installing:
yum install -y libmlx4.x86_64
I can mount:
/usr/bin/mount -t glusterfs -o
backup-volfile-servers=10.10.10.44:10.10.10.42:10.10.10.41,transport=rdma
10.10.10.44:/GluReplica /mnt
10.10.10.44:/GluReplica.rdma 3770662912 407817216 3362845696 11% /mnt
Looks the rdma and gluster are working except ovirt GUI:(
With MountOptions:
backup-volfile-servers=10.10.10.44:10.10.10.42:10.10.10.41,transport=rdma
I am not able to activate storage.
