Step 1: This error is caused by selinux on CentOS 7. Do the following /etc/selinux
Trying to use the command “setenforce 0” does not seems to be able to fix the issue.
Step 2: Remember to install GNOME Desktop
# yum groupinstall "GNOME Desktop" "Graphical Administration Tools"
Step 3: Uninstall the StarNetFastX2 and reinstall
# rpm -e StarNetFastX2
# rpm -Uvh --force StarNetFastX2-2.4.7.rhel6.x86_64.rpm

Current operating system: "Linux"
./StartGUI.sh: .: .: line 3: lsb_release: not found
Unknown linux release ""
# yum install redhat-lsb-core
[root@node-h001 1]# lsb_release
LSB Version: :core-4.1-amd64:core-4.1-noarch
Before restarting the NSD Nodes or Quorum Manager Nodes or other critical nodes, do check the following first to ensure the file system is in the right order before restarting.
1. Make sure all three quorum nodes are active.
# mmgetstate -N quorumnodes
*If any machine is not active, do *not* proceed
2. Make sure file system is mounted on machines
# mmlsmount gpfs0
If the file system is not mounted somewhere, we should try to resolve it first.
