[Gluster-devel] clarification regarding the "2 mirrored servers" example on the wiki

[Krishna Srinivas]

Hi Daniel,

You could do that setup, but a better approach would be to make the
server processes on storage servers directly talk to clients on the webservers.
(instead of re-exporting) just as shown in the example link you gave.

Regards
Krishna
