logical volume

[Carmen Sarlo]

I want to create a logical volume on my internal drive. It's group is vg00. I currently have a 9GB physicaldrive used for that group. 4GB is already in use by the other volumes in that group and 4GB is used for swap. I have to extend one of the volumes and create a new volume. The volume that I have to extend I would need an exta 500MB and the volume to create I need 750MB. Can I use space from another volume? Say vg04?

The short answer is: NO

You can't use space from one VG (vg04 in your case) to extend a LV on another VG (vg00). The easiest thing for you to do would be to create another LV on vg04 that is the new one that you need and mount it appropriately.

I would put as few new LVs as possible in vg00. That makes it that much easier to back up and restore your system if you ever have a disk go bad.
