[Gluster-users] GlusterFS over LVM (thick not thin!)

In our environment the systems all had raid controllers so the LVM would 
only fail if we lost the raid array.

As a general rule I use LVM on all my systems disks.
It has saved me a few times.

On the other hand gluster is designed to just handle a bunch of 
individual disks so there is some value in the simplicity of just using 
raw drives.

Our requirement was for simple mirroring of a VERY large filesystem so 
using a hardware raid array was the easiest way to go.
