RE: [linux-lvm] HUGE LVM log file...

["Gonyou, Austin" <austin coremetrics com>]

Is there a how-to or cookbook type doc which tells how/why you should setup
your LE/PE's? Outter tracks/inner tracks, speed areas, etc?
Theory around this is a good thing with relation to LVM and using it. Any
ideas on that?
