gluster volume status

Description of problem:
gluster volume status returns N/A for Ports despite the bricks being online and functional. The glusterd log file also fills up with "[2013-08-27 10:39:47.875339] E [socket.c:2788:socket_connect] 0-management: connection attempt failed (Connection refused)" every 3 seconds.

An strace determined that glusterd is attempting to connect to 

Although that file exists, lsof shows no open connections. Perhaps related, that socket file also existed in /tmp.

restarting glusterd has no effect.

md5 hash calculations for all bricks

These are the md5 hashes for all my bricks. Notice that 4efb008e4e433ff7735a5a76111461d1 doesn't exist.
Comment 3 Joe Julian 2013-08-28 18:22:44 EDT
Aha, found the connection attempt failure. Looks like it's because I don't have any of my volumes available via nfs:

[2013-08-28 22:07:03.333679] D [run.c:190:runner_log] 0-: Starting the nfs/glustershd services: /usr/sbin/glusterfs -s localhost --volfile-id gluster/nfs -p /var/lib/glusterd/nfs/run/nfs.pid -l /var/log/glusterfs/nfs.log -S /var/run/4efb008e4e433ff7735a5a76111461d1.socket

4efb008e4e433ff7735a5a76111461d1 is the md5sum for /var/lib/glusterd/nfs/run/run-ceed91d5-e8d1-434d-9d47-63e914c93424 where that's the UUID for this server in glusterd.info.

GlusterFS 3.7.0 has been released (http://www.gluster.org/pipermail/gluster-users/2015-May/021901.html), and the Gluster project maintains N-2 supported releases. The last two releases before 3.7 are still maintained, at the moment these are 3.6 and 3.5.

This bug has been filed against the 3,4 release, and will not get fixed in a 3.4 version any more. Please verify if newer versions are affected with the reported problem. If that is the case, update the bug with a note, and update the version if you can. In case updating the version is not possible, leave a comment in this bug report with the version you tested, and set the "Need additional information the selected bugs from" below the comment box to "bugs@gluster.org".

If there is no response by the end of the month, this bug will get automatically closed.

GlusterFS 3.4.x has reached end-of-life.

If this bug still exists in a later release please reopen this and change the version or open a new bug.
