Hi Ted!
Thanks for your reply, for the implementation of Service N2 (As2
Mendelson B45 + gluster 3.3.1-15.el6.x86_64 (1 brick)
we have implemented one brick
As you can see, Mendelson has a Brick, and use it for to process teh
Purchase Ordes feed in SOA21 by MULE process
[root at mendelson ~]# gluster volume info
Volume Name: m2mas2
Type: Distribute
Volume ID: 328d1e48-bb0a-4b41-92ac-699f78d2dca7
Status: Started
Number of Bricks: 1
Transport-type: tcp
Bricks:
Brick1: mendelson.XXXXX.b2b:/opt/mendelson/messages
Options Reconfigured:
auth.allow: 10.200.20.*,10.200.22.*
storage.owner-uid: 500
storage.owner-gid: 500

In this machine run MULE process for to feed with Purchase Orders to
Mendelson.

(rw,allow_other,max_read=131072)
maybe you.'re right and we are wrong with the way of architecture....
Thanks in Advance
