I am getting the following error while deploying the VM:
What is it related to exactly?
OS name ---- CentOS 7
check Firewall settings" --Firewall disabled in all the nodes
getenforce gives what output?

iptables -F
check date of the worker & node is same
is the ds properly mounted? --Yes
Are you sure you’ve followed the installation guide?
Looks like you’ve missed at least Step 3. Disable SElinux in CentOS/RHEL 7.
I’d recommend walking through the entire installation and check is everything Ok.
Best Regards,

I have disabled SELINUX on all the server but it shows enforcing:

Quoting the last line in the above link:
“After this file is changed reboot the machine.”
It’ll be hard to name it Security Enhanced linux if it is so trivial to completely disable

Thank you for the help
