Can't add second disk to FC4 to rsync every night.

[Jim Christiansen]

So I've been poking around and haven't figured out how to add a second hard 
disk to my system that won't be tied into my existing volume.

I have had several RH 7.3 & 9 systems that rsynced to a separate drive every 
night as my method of backup.  Two times in the last 3 years I have had hda 
disks fail and just purchased newer bigger drives, installed them as hda 
with the lastest RH or FC1, and restored my shadow, group, ... homes and 
other configs to the new system.  Each time this has happened I have never 
even needed to worry.

Now it seems that with LVM the drives are tied together into a bigger 
volume.  I don't want this.  I want to keep them separate.

Any whoo...  I have just installed a second ide drive as a slave and powered 
up my system only to have a kernel panic after grub.  The error I get is:

Couldn't find all physical volume for volume group VolGroup00
Inconsistent metadata copies found - updating to use version 6
.
.
.
mount: error 6 mounting ext3
.
.
.
switchroot: mount failed: 22
Kernel panic - not syncing: Attempted to kill init!

My disks are jumpered properly and the second disk (slave) was working in 
the same box with an old FC3 but was a member of the whipped out FC3 
VolGroup00

Is there something I should do first?

Thanks,  Jim
