#1.) It should just appear as unpartitioned space to the OS. You can then partition it and add that partition to one of your LVs, and then use the LVM and ext filesystem tools to grow your existing LV and then resize the filesystem to fit.
Good articles on LVM: - http://kbase.redhat.com/faq/FAQ_96_4842.shtm - http://www.linux.com/base/ldp/howto/LVM-HOWTO/extendlv.html - http://tldp.org/HOWTO/LVM-HOWTO/extendlv.html - http://www.netadmintools.com/art367.html
Once you learn to use LVM to your advantage you will wonder how you ever got along without it. :) Especially when you start dealing with DAS and storage shelves, etc.

Hi all,
I have Dell 2950 III with RAID-5 installed and managed by hardware Raid controller, I also use LVM when install CentOS. Now I get more 03 Hard disk and I would like to add it in to the running system. My question is:
- if new hard disks add in to the machine, I have to rebuild the RAID
volume with RAID management (raid controller) and the volume will be expanded, but is that make any problem to LVM at OS level ?
- if (1's) answer is YES, what I need to do to prevent trouble
occur ?
