James, we are implementing dynamic volume management right now as we speak.

Mic,

Thanks for your quick response. At least I know that what I thought I had to do is correct.

It does give me pause about implementing Gluster with this kind of limitation - the group that will be using this storage tends to outgrow whatever they're given at a phenomenal pace - so adding bricks and arrays will be a common occurrence.

I know the Gluster developers are busting their butts getting us this really amazing tool. Hopefully, something to help with this scenario will be forthcoming in the relatively near future.

James

Importance: Low

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!
