[Gluster-users] Bricks vs LVM

[Juan José Pavlik Salles]

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.
