Very well written. good reference material.
I have 2 suggestions :
1. glusterfs-server package provides firewalld service file which opens up the required ports. You can use this service file, instead of opening ports one by one.
# firewall-cmd –zone=public –add-service=glusterfs
# firewall-cmd –zone=public –add-service=glusterfs –permanent

2. Striped volumes are getting deprecated soon with glusterfs-3.9

good article and thanks for sharing!

There are a few typos that I would like to highlight (–permanent) (double –)

sudo tee gfs.fw <<-'EOF'
sudo systemctl enable firewalld
sudo systemctl start firewalld
sudo firewall-cmd –permanent –zone=public –add-port=24007-24008/tcp
sudo firewall-cmd –permanent –zone=public –add-port=24009/tcp
sudo firewall-cmd –permanent –zone=public –add-service=nfs –add-service=samba –add-service=samba-client
sudo firewall-cmd –permanent –zone=public –add-port=111/tcp –add-port=139/tcp –add-port=445/tcp –add-port=965/tcp –add-port=2049/tcp –add-port=38465-38469/tcp –add-port=631/tcp –add-port=111/udp –add-port=963/udp –add-port=49152-49251/tcp
sudo systemctl reload firewalld
sudo systemctl status firewalld
EOF

and pls add a note for nfs …

sudo systemctl stop nfs-lock.service
sudo systemctl stop nfs.target
sudo systemctl disable nfs.target
sudo systemctl start rpcbind.service

— to fix user not allowed issues by doing the above and also check /etc/exports and /etc/allow
