[Gluster-users] nfs

[Ted Miller]

You do not create anything on "one volume".  That will not replicate properly.

Mount the /gluster/ volume -- in a different place -- and create the volume 
on the /gluster/ volume.  It will then replicate to both bricks.

Line in /etc/fstab should look like:
primary:str      /mnt/glusterfs *glusterfs*    default 0 0
or
primary:/str      /mnt/glusterfs *nfs* default    0 0

When you mount the /gluster/ volume, it does not "replicate from one brick to 
another" it is created on both bricks at the same time".

If you mounted the volume correctly, you can just look at the bricks on each 
server, and you can see what is replicated.  The entire file structure will 
be there.

P.S.  This is one of the most common mistakes made by newbies. Don't feel bad 
if you made it.  If you did not, congratulate yourself.
