Install FC3 into lvm w/striping

[Neal D. Becker]

I am about to try update from FC2 -> FC3T2.  I have 2 FC2 systems, both are
installed into LVM2 root.  The LVM2 were created by install of FC1 or FC2
(I forget which).

Turns out, I just notice, that I although the installer told me the disks
were stripped, apparantly they are not!

Note: the first logical volume I just created, and it IS stripped, but the
second was created by anaconda - and is NOT stripped:

sbin/lvm lvdisplay -m

So, what if anything did I do wrong?  Or was this a problem with the older
install?  Is it fixed?
