OK so,

I enabled the firewall service as recommended but it was already enabled.

I scrubbed the whole setup again with

ovirt-hosted-engine-cleanup
vdsm-tool configure --force
systemctl restart libvirtd
systemctl restart vdsm

I restarted all hosts again.

I went to the setup Gluster & Engine button and selected with the recognised already set up Gluster.

I got this far with the gluster storage recognised by the system for the first time..

The wizard automatically returning this configuration.

Storage
Storage Type:glusterfs
Storage Domain Connection:gfs1.gluster.private:/engine
Mount Options:backup-volfile-servers=gfs2.gluster.private:gfs3.gluster.private
Disk Size (GiB):58

Installation failed again with…

You need to set it also permanent via '--permanent', otherwise  after a reload - it's gone.

Rather than disabling firewalld,
You can add the ports and restart the firewalld service

# firewall-cmd --add-service=cockpit
# firewall-cmd --add-service=cockpit --permanent

firewalld is running?

systemctl disable --now firewalld

It can’t be DNS, since the engine runs on a separate network anyway ie front end, so why can’t it reach the Volume I wonder

There could be two reason
1- Your gluster service may not be running.
2- In Storage Connection  there mentioned <volumename> may not exists

can you please paste the output of "gluster volume status" ?
