Hi All, I have referred http://www.gluster.org/community/documentation/index.php/Basic_Gluster_Troubleshooting 1. What ports does Gluster need? Preferably, your storage environment should be located on a safe segment of your network where firewall is not necessary. In the real world, that simply isn't possible for all environments. If you are willing to accept the potential performance loss of running a firewall, you need to know that Gluster makes use of the following ports: - 24007 TCP for the Gluster Daemon - 24008 TCP for Infiniband management (optional unless you are using IB) - One TCP port for each brick in a volume. So, for example, if you have 4 bricks in a volume, port 24009 – 24012 would be used in GlusterFS 3.3 & below, 49152 - 49155 from GlusterFS 3.4 & later. - 38465, 38466 and 38467 TCP for the inline Gluster NFS server. - Additionally, port 111 TCP and UDP (since always) and port 2049 TCP-only (from GlusterFS 3.4 & later) are used for port mapper and should be open. Note: by default Gluster/NFS does not provide services over UDP, it is TCP only. You would need to enable the nfs.mount-udp option if you want to add UDP support for the MOUNT protocol. That's completely optional and is up to your judgement to use. Here we say that a port will be associated with all the brick for a volume. I would like to know how is this port number incremented ? Is it always sequential, meaning that if first brick will have port 49152 then will the second brick have port 49153 ? Is their any such scenario where port number would not be sequential ? Is their a way to give a range of ports for bricks?
