[Gluster-users] After reboot, one brick is not being seen by clients

We are currently using gluster with 3 bricks.  We just
rebooted one of the bricks (mseas-data, also identified
as gluster-data) which is actually the main server.  After
rebooting this brick, our client machine (mseas) only sees
the files on the other 2 bricks.  Note that if I mount
the gluster filespace (/gdata) on the brick I rebooted,
it sees the entire space.

The last time I had this problem, there was an error in
one of our /etc/hosts file.  This does not seem to be the
case now.

What else can I look at to debug this problem?

Some information I have from the gluster server

[root at mseas-data ~]# gluster --version
