Hi, I have a requirement to run my gluster hosts within a firewalled section of network and where the consumer hosts are in a different segment due to IP address preservation, part of our security policy requires that we run local firewalls on every host so I have to get the network access locked down appropriately.
I am running 3.5.2 using the packages provided in the Gluster package repository as my Linux distribution only includes packages for 3.2 which seems somewhat ancient. Following the documentation here: http://www.gluster.org/community/documentation/index.php/Basic_Gluster_Troubleshooting I opened up the relevant ports: 34865 – 34867 for gluster 111 for the portmapper 24009 – 24012 as I am using 2 bricks This though contradicts: http://gluster.org/community/documentation/index.php/Gluster_3.2:_Installing_GlusterFS_on_Red_Hat_Package_Manager_(RPM)_Distributions Which says: "Ensure that TCP ports 111, 24007,24008, 24009-(24009 + number of bricks across all volumes) are open on all Gluster servers. If you will be using NFS, open additional ports 38465 to 38467" What has not been helpful is that there was no mention of port: 2049 for NFS over TCP - which would have been helpful and probably my own mistake as I should have known. To really confuse matters I noticed that the bricks were not syncing anyway, and a look at the logs reveals: /var/log/glusterfs/glfsheal-www.log:[2014-10-30 07:39:48.428286] I [client-handshake.c:1462:client_setvolume_cbk] 0-www-client-1: Connected to 111.222.333.444:49154, attached to remote volume '/srv/hod/lampe-www'. along with other entries that show that I also actually need ports: 49154 and 49155 open. even gluster volume status reveals some of the ports: gluster> volume status Status of volume: www Gluster process Port Online Pid ------------------------------------------------------------------------------ Brick 194.82.210.140:/srv/hod/lampe-www 49154 Y 3035 Brick 194.82.210.130:/srv/hod/lampe-www 49155 Y 16160 NFS Server on localhost 2049 Y 16062 Self-heal Daemon on localhost N/A Y 16072 NFS Server on gfse-isr-01 2049 Y 3040 Self-heal Daemon on gfse-isr-01 N/A Y 3045 Task Status of Volume www ------------------------------------------------------------------------------ There are no active volume tasks So my query here is, if the bricks are actually using 49154 & 49155 (which they appear to be) why is this not mentioned in the documentation and are there any other ports that I should be aware of?
