Re: LVM2

["Trever L. Adams" <tadams-lists@myrealbox.com>]

PV = the device
VG = groups of them (the RAID5 array?)
LV = what? the file system?

So, from what you are telling me, and the man page, 2.6.x with LVM2 can
have basically any size of PV, VG, and LV I want.

Am I flawed in my understanding?

Thank you,
Trever
