The redhat admin guides are pretty good You could also try http://tldp.org/HOWTO/LVM-HOWTO/index.html but that looks a little out of date to me. I can give you a quick overview: A volume group is made of one or more physical volumes. A volume group can be divided up into logical volumes. You create filesystems on these logical volumes. So: pvcreate /dev/<the-partition-or-disk> vgcreate <some-volume-group> /dev/<the-partition-or-disk> lvcreate --size 10g <some-volume-group> mkfs.ext3 /dev/<some-volume-group>/<some-logical-volume> then add that to /etc/fstab as well. Use lvdisplay and vgdisplay to show the config. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
