Is it just me or does it seem like your latest mails have been sort of
insulting, and now this mail looks like you are attempting to turn
people away from glusterfs because you could not get it to work in
your situation?

Im not a developer so I cant speak for anyone else, but I dont
remember reading anywhere that glusterfs was production ready, a final
project, or anything to that matter? Is this not a project in the
works? If it works for you in its current state, super, but otherwise
it is an actively developed project? I also dont remember seeing that
you had to PAY for it anywhere, it is FREE. So to complain about it or
get rude over it, especially when you have not contributed or added
anything constructive to it, well thats kind of lame in my eyes.

Ive read the last couple mails and just thought to myself, god, i hope
the devs dont get pissed or bummed by this guy in any way.

If glusterfs doesnt work in your case, well, great, move on! There
were more than one suggestions about alternatives that were given, but
instead the thread just kept going on with no point in sight.

Not meaning to be a troll myself, or start a flame war but c'mon, its
free software, if it doesnt work for you dont bitch about it, move on
to something else, or help write a translator or whatever that does
what YOU want it to do.

Kudos to the guys/gals that have worked so hard on glusterfs, it seems
like such a kickass project. I have not implemented it into a
production environment myself YET, but I except there to be bugs and
things not working perfectly yet. As far as I know this is still a
fairly young project. My biggest hurdles has just been the learning
curve and how to set up the bricks in the various ways. But not once
have I complained that it didnt work right when it hasnt worked the
way I wanted it, most likely due to my lack of knowing how to properly
configure it.
