Section Number and Name: 

Section 6.1 Configuring Port Access

Describe the issue: 

Firewall rules given in 6.1 don't match up with those found in Section 8.2.1 when running cns-deploy under OCP 3.7

Suggestions for improvement: 

Have the list provided in 6.1 match those given by cns-deploy (and brick multiplexing)

Additional information: 

Section 6.1:
On each of the OpenShift nodes that will host the Red Hat Gluster Storage container, add the following rules to /etc/sysconfig/iptables in order to open the required ports:
-A OS_FIREWALL_ALLOW -p tcp -m state --state NEW -m tcp --dport 24007 -j ACCEPT
-A OS_FIREWALL_ALLOW -p tcp -m state --state NEW -m tcp --dport 24008 -j ACCEPT
-A OS_FIREWALL_ALLOW -p tcp -m state --state NEW -m tcp --dport 2222 -j ACCEPT
-A OS_FIREWALL_ALLOW -p tcp -m state --state NEW -m multiport --dports 49152:49664 -j ACCEPT
-A OS_FIREWALL_ALLOW -p tcp -m state --state NEW -m tcp --dport 24010 -j ACCEPT
-A OS_FIREWALL_ALLOW -p tcp -m state --state NEW -m tcp --dport 3260 -j ACCEPT
-A OS_FIREWALL_ALLOW -p tcp -m state --state NEW -m tcp --dport 111 -j ACCEPT
Note

Port 24010 and 3260 are for gluster-blockd and iSCSI targets respectively.

cns-deploy....:
Each of the nodes that will host GlusterFS must also have appropriate firewall
rules for the required GlusterFS ports:
 * 111   - rpcbind (for glusterblock)
 * 2222  - sshd (if running GlusterFS in a pod)
 * 3260  - iSCSI targets (for glusterblock)
 * 24006 - glusterblockd
 * 24007 - GlusterFS Management
 * 24008 - GlusterFS RDMA
 * 49152 to 49251 - Each brick for every volume on the host requires its own
   port. For every new brick, one new port will be used starting at 49152. We
   recommend a default range of 49152-49251 on each host, though you can adjust
   this to fit your needs.

Please ask development for the correct Firewall rules.
