The vol file for 2.x would be in /etc/glusterfs/<volume

This would not appear if the glusterfs-volgen command wasn't used

<pre wrap="">If the volume was created in a different order than before, then it is

If this is the case, recreating the volume in the correct order should
show the files from the mount.
If the volume was recreated properly, make sure you have followed the
upgrade steps to go from versions prior to 3.1:

This would explain why the files can't be viewed from the client, but
the size discrepancy isn't expected if we see the expected output from
df for the bricks.

Subject: Re: [Gluster-users] FW: cant mount gluster volume
Steve,
The volume is a pure distribute:
</pre>
<blockquote type="cite">
<pre wrap="">Type: Distribute
</pre>
</blockquote>
<pre wrap="">In order to have files replicate, you need
1) to have a number of bricks that is a multiple of the replica count,
e.g., for your three node configuration, you would need two bricks per
node to set up replica two. You could set up replica 3, but you will
take a performance hit in doing so.
2) to add a replica count during the volume creation, e.g.
`gluster volume create <vol name> replica 2 server1:/export server2:/export
>From the volume info you provided, the export directories are different
for all three nodes:
Brick1: gluster-0-0:/mseas-data-0-0
Brick2: gluster-0-1:/mseas-data-0-1
Brick3: gluster-data:/data
Which node are you trying to mount to /data? If it is not the
gluster-data node, then it will fail if there is not a /data directory.
In this case, it is a good thing, since mounting to /data on gluster-0-0
or gluster-0-1 would not accomplish what you need.
To clarify, there is a distinction to be made between the export volume
mount and the gluster mount point. In this case, you are mounting the
brick.
In order to see all the files, you would need to mount the volume with
the native client, or NFS.
For the native client:
mount -t glusterfs gluster-data:/gdata /mnt/<gluster mount dir>
For NFS:
mount -t nfs -o vers=3 gluster-data:/gdata /mnt/<gluster mount dir>

I had some mounting issues yesterday, from a rocks 6.2 install to the cluster. I was able to overcome those issues and mount the export on my node. Thanks to all for your help.
However, I can only view the portion of files that is directly stored on the one brick in the cluster. The other bricks do not seem to be replicating, tho gluster reports the volume as up.

Any help with troubleshooting why we are only seeing data from 1 brick of 3 would be appreciated,

Subject: cant mount gluster volume
I am still unable to mount a new 3.3.1 glusterfs install. I have tried from one of the actual machines in the cluster to itself, as well as from various other clients. They all seem to be failing in the same part of the process.
