Of course there's about 50 ways to do something about this but as long as you don't care about data reliabilty, the easiest thing would be to make the 80gb drive part of your existing "vg_box9" volume group. Add some of all of the extents to your "lv_home" logical volume and then resize your partition to fill the LV. Keep in mind, if one of the two drives go bad you'll probably loose all of /home so caveat emptor applies. The 80gb LVM drive may or may not already have a volume group (VG) associated with it, if so you might have to add "-f" to vgextend. First you need to add /dev/sb1 to your volume group, i.e.: vgextend -f vg_box9 /dev/sdb1 but I would try without the -f first and see if it complains. Then you need to expand your "lv_home" logical volume over /dev/sdb1. lvextend /dev/vg_box9/lv_home /dev/sdb1 This is a short cut to have lv_home use all of /dev/sdb1, usually you would have to tell it how much of the vg you want to use but if you specify the device it uses all of it. If your brave enough to let it call resizefs for you, add the '-r' option. You didn't say what the underlying file system is so you need to know if it supports online resizing or not. If not then you need to boot a live CD/USB stick although going into single user mode would probably let you unmount /home as well. I hope this helps but as usual, no warranty on the results and be sure to backup anything critical.
