Gluster users - Sep 2014 - Bricks vs LVM

What would you say are the efficiencies of using LVM to upgrade and add capacity
to the glusterFS and this increasing the size of the bricks? Does gluster need
to do anything when bricks are increased in size suddenly?

Or should I really be not using LVM and adding more bricks explicitly?

Just been thinking about this slide deck

And why LVM is optional - I want to simplify my grid as much as poss. 

Cheers Mark

Hi Mark, as far as I know LVM gives you mainly flexibility. For instance if
you have a big RAID 5 volume, you can split it in smaller pieces and make
bricks for different volumes instead of having just a big brick. If you
want to keep things simple you can avoid LVM as long as you don't really
need it.
