It's because currently expansion will involve either:
a) increasing the capacity of existing bricks and bringing them back
online to replicate changes (not super useful)
b) unmounting the client file system. to add storage bricks (useful but
disruptive)
Growing the storage by adding a server brick without an outage is on the
road map but not yet implemented.
If anyone knows any different please let me know.
Thanks!

Hello,
I've searched through all my gluster-users archives, and I have yet to find a
documented step by step procedure for adding bricks to Gluster storage in a
replicated then distributed configuration.
I did find this one post from Liam Slusser [[email protected]] on Mon 1/4/2010
7:29 PM titled: adding another brick howto - but there were zero responses to
his post.
Since one of the stated benefits of Gluster is easy expansion, I'm frustrated
by the idea that I'm going to have to hack my way through configuration files
or just wholly reconfigure my PFS in order to accommodate this expansion.
Thanks in advance for any pointers.
James

It turns out I had a previous client version (2.09) running on a
separate server. Is there still a bug listed for this? It makes
upgrading very painful.
Also I'm pretty sure mmaps didn't seem to work even with the
disable-direct-io option. I was running kernel ver 2.6.24.4 but ver 2.09
works where 3.04 hangs the client (running VMs from gluster). Only some
hypervisors failed but it looked like it was a mmap problem.
Any ideas on what would cause this?

Hi Mickey,
Please open a defect in bugzilla. Someone from the dev team will have a look at
it soon.

Did a strait install and the ibverbs instance will crash after a
single connection attempt. Are there any bugs that would cause this
behavior?
All the log tells me is:
