Things are rough 🙂  it seems node 192.168.15.102  peering was not done/ready.  I made a small modification to the steps maybe it will work. Also if this is test cluster you just installed it may be easy to try re-install it should not take long, so..

try to do the following on all 3 nodes:

systemctl stop petasan-mount-sharedfs
systemctl stop glusterfs-server
killall glusterfsd
killall glusterfs

rm -rf /var/lib/glusterd/vols/gfs-vol
rm -rf /opt/petasan/config/gfs-brick
mkdir -p /opt/petasan/config/gfs-brick

Then after the above is done on all 3 nodes, start the following services on all 3 nodes:

systemctl start petasan-mount-sharedfs
systemctl start glusterfs-server

then on all 3 nodes run

gluster peer status

and make sure on all 3 nodes each node sees the other 2 peers as "Connected", sometimes it takes a couple of seconds after service restart, so check the status a couple of times.

then do this from any node

#create volume: note replace IP1, IP2, IP3 with the ip addresses of your backend 1 ip for nodes 1,2,3 respectively:
gluster vol create gfs-vol replica 3 IP1:/opt/petasan/config/gfs-brick IP2:/opt/petasan/config/gfs-brick IP3:/opt/petasan/config/gfs-brick

# start volume
gluster vol start gfs-vol
gluster vol set gfs-vol network.ping-timeout 5
gluster vol set gfs-vol nfs.disable true

# check volume is working
gluster vol info gfs-vol
