Workaround

change the two directory access permission as below showing:
# ls /rhev/data-center/mnt/
drwxrwxrwx. 3 vdsm kvm 4096 Jul 15 17:54 128.224.165.233:_media_sda1_export_data
drwxrwxrwx. 2 vdsm kvm 4096 Jul 15 05:46 128.224.165.233:ssme

or 

change the two exported directory access permission and do re-mount operations
# ls /media/sda1/export/ -l 
drwxrwxrwx. 3 root root 4096 Jul 15 17:41 brick1
drwxrwxrwx. 3 root root 4096 Jul 15 17:41 brick2
drwxrwxrwx. 3 vdsm kvm  4096 Jul 15 17:54 data

Steps to Reproduce

1) /lpg-build/cdc/fast_prod/wrlinuxovp/wrlinux-x/wrlinux/configure --enable-jobs=8 --enable-parallel-pkgbuilds=4 --enable-kernel=preempt-rt --enable-addons=wr-ovp --enable-rootfs=ovp-ovirt-node --enable-board=intel_xeon_core --with-rcpl-version=0
2) setting nfs exported directory and glusterfs bricks directory.
3) start vdsmd, glusterd, nfsserver services
4) create mount point in data-center directory and do mount job. 
    # ls /rhev/data-center/mnt/ -l
    drwxr-xr-x. 3 vdsm kvm 4096 Jul 15 17:54 128.224.165.233:_media_sda1_export_data
    drwxr-xr-x. 2 vdsm kvm 4096 Jul 15 05:46 128.224.165.233:ssme
5) run create-domain scripts
    # python nfs_vdsm_storage.py  or 
    # python glusterfs_vdsm_storage.py
