Hey...I'm still sensitive about how you flamed me 3 years ago when I

I figured that part out even though I didn't need to.  Webmin can do 
this all easily.

The question is whether Centos 4 will recognize the extra space after I 
extend the size of the existing logical drive using the HP array 
utility.  If not then I have to add the extra space as another logical 
drive and tell LVM to add it as a new physical volume before extending 
the volume size.

I was hoping that someone on this list, given the vast amount of Linux 
experience some people (like yourself) have, that this is something that 
can be answered easily.
