Also, we changed the default port from 6996 to 24007 in 3.1.x version, so obviously there is nothing on 6996 after you upgraded. This was the initial (default) config: Given volfile: +------------------------------------------------------------------------------+ 1: volume management 2: type mgmt/glusterd 3: option working-directory /etc/glusterd 4: option transport-type socket,rdma 5: option transport.socket.keepalive-time 10 6: option transport.socket.keepalive-interval 2 7: end-volume 8: and it reported errors like this: [2011-01-07 21:03:06.219877] I [glusterfsd.c:672:cleanup_and_exit] glusterfsd: shutting down [2011-01-07 21:03:08.286880] I [glusterd.c:275:init] management: Using /etc/glusterd as working directory [2011-01-07 21:03:08.289496] E [socket.c:322:__socket_server_bind] socket.management: binding to failed: Address already in use [2011-01-07 21:03:08.289544] E [socket.c:325:__socket_server_bind] socket.management: Port is already in use [2011-01-07 21:03:08.289652] I [glusterd.c:87:glusterd_uuid_init] glusterd: retrieved UUID: 8563bfd6-4ce9-4aa3-bef5-a20597dda496 [2011-01-07 21:03:08.292233] W [rpc-transport.c:849:rpc_transport_load] rpc-transport: missing 'option transport-type'. defaulting to "socket" [2011-01-07 21:03:08.293277] I [glusterd-handler.c:2600:glusterd_friend_add] glusterd: connect returned 0 [2011-01-07 21:03:08.296098] W [rpc-transport.c:849:rpc_transport_load] rpc-transport: missing 'option transport-type'. defaulting to "socket" I changed transport-type to 'tcp' and all the errors went away. Now I look, it is indeed working on port 24007. I changed the transport-type back to the original, restarted it and found that it still works - but why is it now using a transport-type that's not listed? In searching the docs again, I can still only find documentation on transport-type for gluster versions older than 3.0. > Is there some documentation or howto for getting gluster 3.1.1 working over tcp?

Please refer to http://www.gluster.com/community/documentation/index.php/Gluster_3.0_to_3.1_Upgrade_Guide and let us know what exactly was the problem in upgrading. The main problem I found with that page is that it didn't actually say much that was very useful - it's a leaf node (not a root) of a whole tree of docs you then need discover and read in order to do the upgrade - for example the need for a server pool is not mentioned at all when it's a vital new concept. I'm installing on Ubuntu, but I have now found the firewall info on the redhat install page (and nowhere else according to a search). I don't think firewall config belongs on OS-specific pages. You could show how to open ports on each specific OS, but the general requirements should documented independently and findably - searching for 'firewall port' doesn't find it. Overall I found the older (obsolete) user guide much more usable, but obviously that's out of date. A nicer upgrade path would be one that reads a volfile (maybe just the volgen line) and emits a series of gluster client commands to build the same structure. I shall persevere... Marcus
