How do you add another drive to your existing system?
 

My current system has only one hdd (hda) but my /home is running out of space. How do I move /home to a new hdd (hdb)? Thanks!

Install your new drive, format it using mkfs, mount it somewhere temporarily (/tmp/home for example), copy the contents of home to your new drive, unmount it again, rename your old /home to /home-old, create an empty directory at /home then remount your new drive at /home. Don't forget to add an entry to /etc/fstab so that it automatically gets mounted at boot.

Does LFS VolumeGroup deal with this kind of matter? I read somewhere, but am uncertain, that you could actually just extend your /home so it resides both on the old harddisk and the new one, but so that it apperas as one. I may be mistaken, but anyway..many "modern" distributions seem to use these VolumeGroups (Fedora Core and Ubuntu, for a start). The goal is, if I got it right, to make it easier to add storage media (like harddisks) to the existing system, resize (grow/shrink) mounted partitions (like /home for example) etc.

Just a thought, no idea how it actually works (as of now).

If you mean LVM, then yes, but only if your existing volume is also LVM formatted. Obviously, you can't extend an LVM volume if you don't have one to begin with. But LVM is great for this sort of thing where you want to spread a volume across multiple disks without resorting to RAID.
