[ale] live cd for partitioning LVM partitions.

[Van Loggins]

The main issues, is that RHEL5 doesn't 
allow you to make changes to your / 
partition if it's mounted. Our current 
method involves booting to a specially 
created RHEL based rescue system that 
lives on our PXE server so we can work 
on changing the LVM partitions and 
layout without them being mounted.

Most of my team members are less savvy 
with the linux command line than I am 
(and I don't claim to be an expert with 
it by any means) so was hoping to find a 
good GUI based partition editor that is 
able to work with LVM partitions so I 
can help make the process easier.

I'll take a look at the gparted live cd, 
Parted Magic also uses gparted, but they 
may be further behind the gparted team 
on the version that is being used for 
parted magic.

Thanks

Van Loggins, A+

The main point in LVM is that you can add/delete/resize things as you desire without impacting other parts of the layout as compared to standard partitioning.  You can even rename a VG or LV if you want so "relayout" shouldn't really be necessary.
