I have the client running on the headnode, and it has the glusterfs
mounted on /export/gluster. Then, I'm trying to export it from there, and
trying to mount it from my own workstation.

On each of the, um, 30 or so nodes, I've got (leaving out the commented
lines)
volume posix
  type storage/posix
  option directory /glusterfs1
end-volume

volume locks
    type features/locks
    subvolumes posix
end-volume

volume brick
    type performance/io-threads
    option thread-count 8
    subvolumes locks
end-volume

volume server
    type protocol/server
    option transport-type tcp
    option auth.addr.brick.allow *
    option listen-port 6996
    subvolumes brick
end-volume

Then, on the head node, I've got (replacing actual names with <clusternode>):
volume raidvol-0
    type protocol/client
    option transport-type tcp
    option remote-host raidvol-0
    option remote-port 6996
    option remote-subvolume brick
end-volume

volume raidvol-1
    type protocol/client
    option transport-type tcp
    option remote-host raidvol-1
    option remote-port 6996
    option remote-subvolume brick
end-volume

volume <clusternode>002:/glusterfs1
    type protocol/client
    option transport-type tcp
    option remote-host <clusternode>002
    option remote-port 6996
    option remote-subvolume brick
end-volume

volume <clusternode>003:/glusterfs1
    type protocol/client
    option transport-type tcp
    option remote-host <clusternode>003
    option remote-port 6996
    option remote-subvolume brick
end-volume
<...>
volume <clusternode>034:/glusterfs1
    type protocol/client
    option transport-type tcp
    option remote-host <clusternode>034
    option remote-port 6996
    option remote-subvolume brick
end-volume

volume mirror-0
    type cluster/replicate
    subvolumes raidvol-0 raidvol-1
end-volume

volume mirror-1
    type cluster/replicate
    subvolumes <clusternode>002:/glusterfs1 <clusternode>003:/glusterfs1
end-volume

volume mirror-2
    type cluster/replicate
    subvolumes <clusternode>004:/glusterfs1 <clusternode>005:/glusterfs1
end-volume
<...>
volume mirror-15
    type cluster/replicate
    subvolumes <clusternode>033:/glusterfs1 <clusternode>034:/glusterfs1
end-volume

volume distribute
    type cluster/distribute
    subvolumes mirror-0 mirror-1 mirror-2 mirror-3 mirror-4 mirror-5
mirror-6 mirror-7 mirror-8 mirror-9 mirror-10 mirror-11 mirror-12
mirror-13 mirror-14 mirror-15
end-volume

volume writebehind
    type performance/write-behind
    option cache-size 4MB
    subvolumes distribute
end-volume

    type performance/io-cache
    option cache-size 1GB
