[Gluster-users] Query for web GUI for gluster configuration

Gluster is a great concept and I quiet like it, however I also think it has a lot to go yet. Yes it solves peoples problems for certain scenarios but not yet for most of them which I am sure they are working on to solve and with RedHat acquisition it will perhaps be speed up.
I wouldn't be bad to say that 'they' (he doesn't do it alone) are doing it wrong. In many aspects they are doing it well and there has been a many improvements over the past couple of months, but on performance subject they didn't get there yet, that's just a fact either you like it or not, and they acknowledge it already.

My images are, indeed, on the volume. I saw that image-based performance wasn't sufficient so I found a better way. That's my point. Not everyone is restricted from being able to take advantage of a better way. So yes, I mount a GlusterFS volume within a VM whose image resides on a GlusterFS volume.

By the way, you see "9 of 10 people" reporting poor performance in part because the people that don't have poor performance don't complain about it. Your metric is skewed.

I recognize you're upset because your expectations are not being met. 
You're not alone. I'm not alone either. I see about a dozen new users each day that are excited that this software solves a problem for them.

Maybe you should consider posting your use case and seeing if anyone has any suggestions on how you could satisfy that rather than trying to tell Vijay that he's doing it wrong.

So yes it works for low profile virtual server, like quite web servers, etc, but not in general. Any peak you need it can't accomplish and it does need improvements on Gluster code.
