I just looked at A Beginner's Guide To LVM. It seems to be oriented to setting up a raid configuration. I am looking for info about how to mount a slave HDD that has FC4 on a LVM partiton to either a master HDD that is partitioned with LVM running FC5, or a master HDD running FC5 that has been manually partitioned with out LVM. I want to move my HOME and other folders from the slave to the master HDD.
It shows LVM with and without RAID. What are the outputs of Code: fdisk -l , Code: pvdisplay , Code: vgdisplay , and Code: lvdisplay when you plug in the slave HDD to the FC5 system?

I thought that the master HDD would be hda.

I'd create a new volume group and logical volume with /dev/hda2 and then mount it somewhere. Afterwards you can copy the files.
LVM to non LVM I do not want to use LVM on /dev/hdb (the master drive) Here is why: I installed FC5 on a new hard drive using the default LVM. I connected my old hard drive as slave. It had FC4 installed using the default LVM. I was never able to mount any thing from the old hard drive. I was never able to find anyone who knew how t do that. I was advised by many people who had lots of Linux experience to never use LVM, as I would have trouble transferring files from an old slave drive to a new install on a new master drive. I now have FC5 on the new hard drive (hdb)that does not use LVM, and want to move some of my files (home) from hda (slave) to hdb (master) I would also like to know how to do the same in the case that both the master and the slave use LVM. I was suprised that the slave came up as hda, and the master as hdb
You don't need to use LVM on /dev/hdb. If you have a close look at my LVM tutorial, you'll realize that i don't use LVM on /dev/sda there, but still I can mount the logical volumes and use them on the system.
Thanks. I will look at your guide again. I am still wondering why the master HDD (FC5 not LVM) comes up as hdb, and the slave HDD (FC4 LVM) comes up as hda. I would expect the master HDD to come up as hda.
