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.
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.
