Getting Glusterd to start at boot on Centos

I’ve been working on a pair of Centos servers using GluserFS for a volume that is shared by various other servers. Each time the server reboots, I had to log in and manually start the service. Turns out this is due to the networking no yet being started when the glusterd service starts. I found this post with the solution:

• Execute systemctl enable NetworkManager-wait-online
• Add the following to /lib/systemd/system/crond.service under [Unit]:

Requires=network.target
After=syslog.target auditd.service systemd-user-sessions.service time-sync.target network.target mysqld.service

This will allow glusterd to be started after the network has come up.
