Your right Eco
I am only able to telnet on port 24007, ports 24009, 24010 and 24011 are all
connection refused . Iptables is not running on any of the machines
mseas-data 24007, 24009 are open, 24010 and 24011 closed
nas-0-0 24007 open, 24009,24010 and 24011 closed

Hi Eco,
I believe you are asking that I run
find /mount/glusterfs >/dev/null
only? That should take care of the issue?
Meaning, run a recursive find against the client mount point
(/mount/glusterfs is used as an example in the docs). This should solve
the specific issue of the files not being visible.
However, the issue of the disk space discrepancy is different. From the
df output, the only filesystem with 18GB is / on the mseas-data node, I
assume this is where you are mounting from?
If so, then the issue goes back to one of connectivity, the gluster
bricks most likely are still not being connected to, which may actually
be the root cause of both problems.
Can you confirm that iptables is off on all hosts (and from any client
you would connect from)? I had seen your previous tests with telnet,
was this done from and to all hosts from the client machine?
Make sure that at a minimum you can hit 24007, 24009, 24010 and 24011.
This will test the management port and the expected initial port for
each of the bricks in the volume.
Thanks,
Eco
Thanks for your time,
Steve

option transport-type socket,rdma
option transport.socket.keepalive-time 10
option transport.socket.keepalive-interval 2
end-volume
The vol file for 2.x would be in /etc/glusterfs/<volume name>.vol I believe. It
should contain an entry similar to this output for each of the servers toward the top
of the file.
Article you referenced is looking for the words "glusterfs-volgen" in a vol
file. I have used locate and grep, but can find no such entry in any .vol files.
This would not appear if the glusterfs-volgen command wasn't used during
creation. The main consideration is to ensure that you have the command in step
5:
find /mount/glusterfs >/dev/null

Can we see the vol file from the 2.x install and the output of df -h for

Its interesting that "gluster volume info" shows the correct path for each
machine.
These are the correct mountpoints on each machine, and from each machine I can
see the files and structure.
If the volume was created in a different order than before, then it is
expected you would be able to see the files only from the backend
directories and not from the client mount.
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:
http://www.gluster.org/community/documentation/index.php/Gluster_3.0_to_3.2_Upgrade_Guide
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.

I can mount it from the client, but again, there is nothing in it.
Before upgrade this was a 50 TB gluster volume. Was that volume information
lost with upgrade?
Do you have the old vol files from before the upgrade? It would be good
to see them to make sure the volume got recreated properly.
The file structure appears intact on each brick.
As long as the file structure is intact, you will be able to recreate
the volume although it may require a potentially painful rsync in the
worst case.

Subject: Re: [Gluster-users] FW: cant mount gluster volume
Steve,
The volume is a pure distribute:
Type: Distribute
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>
Thanks,
Eco

I have a 3 node gluster cluster that had 3.1.4 uninstalled and 3.3.1 installed.

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

gluster reports the volume as up.

/dev/mapper/the_raid-lv_data /data xfs quota,noauto 1 0

I have to run "mount -t xfs /dev/mapper/the_raid-lv_data /data"
manually to mount it.
Any help with troubleshooting why we are only seeing data from 1 brick of 3
would be appreciated,

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.
