c0d0p5 Logical Linux ReiserFS
c0d0p6 Logical Linux LVM

Cur LV 6

We will be adding additional physical disks to the Raid array as need
dictates - How would I go about making this new free space "available"
for use in the PV?
- Turn off server, add new HD's, boot into HP Top Tools and add the new
drives to the array (Giving additional space).
- cfdisk(or fdisk), delete the data partition(Making note of the
starting cylinder), then recreate the data partition with the same
starting cylinder, but incorporate the new free space.
- pvresize? (I do not seem to have this utility?)
Thanks in advance.
