[Gluster-devel] cluster/unify "option namespace <node>" - self healing feature?

[Harris Landgarten]

You have to export a namespace vol somewhere. I put it on an existing brick this is my spec file for that brick:

### Export volume "brick" with the contents of "/home/export" directory.
volume posix2
  type storage/posix                    # POSIX FS translator
  option directory /mnt/export        # Export this directory
end-volume

volume io-threads
  type performance/io-threads
  option thread-count 1
  subvolumes posix2
end-volume

### Add POSIX record locking support to the storage brick
volume brick
  type features/posix-locks
  option mandatory on          # enables mandatory locking on all files
  subvolumes io-threads
end-volume

### Add network serving capability to above brick.
volume server
  type protocol/server
  option transport-type tcp/server     # For TCP/IP transport
  option listen-port 6996              # Default is 6996
  subvolumes brick
  option auth.ip.brick.allow * # Allow access to "brick" volume
end-volume

volume posix3
  type storage/posix
  option directory /mnt/namespace
end-volume

volume io-threads1
  type performance/io-threads
  option thread-count 1
  subvolumes posix3
end-volume

volume brick-ns
  type features/posix-locks
  option mandatory on
  subvolumes io-threads1
end-volume

volume server
  type protocol/server
  option transport-type tcp/server
  option listen-port 6997
  subvolumes brick-ns
  option auth.ip.brick-ns.allow *
end-volume

Then in the client specify the nameserver vol as a client and use that client in the unify volume:

volume client-ns
  type protocol/client
  option transport-type tcp/client     # for TCP/IP transport
  option remote-host 10.255.57.171     # IP address of the remote brick
  option remote-port 6997          # default server port is 6996
  option remote-subvolume brick-ns        # name of the remote volume
end-volume

volume bricks
  type cluster/unify
    option namespace client-ns # this will not be storage child of unify.
    subvolumes client1 client2
   
etc.

Anyone have any more info on the new "option namespace <node>" in the unify 
xlator.
bulde wrote some new docs today, but it didn't really answer my question as 
what
<node> is supose to be. It seems to have broken my setup.

Is it supose to be an existing volume?
is it supose to be "namespace-child"?
is it supose to be ????

i tried all of them, but nothing seems to work, and glusterfs seems to exit 
without it set.
