    Yes, I posted the question and found the response interesting and
    helpful. I spent a couple of hours reading man pages and
    experimenting with the lvm commands on various drives.

    But I have not been able to open a volume and list the directories
    and files, such as /home and /etc! I must be dense ...

    This from another drive:

        [root at box6 bob]# lvm
        lvm> pvdisplay
           --- Physical volume ---
           PV Name               /dev/sdb2
           VG Name               VolGroup00
           PV Size               74.43 GB / not usable 22.62 MB
           Allocatable           yes
           PE Size (KByte)       32768
           Total PE              2381
           Free PE               1
           Allocated PE          2380
           PV UUID               J5Yc28-aO4n-ODWI-1c0W-H9Jr-04jN-ufwyRj

        And fdisk shows:

        Disk /dev/sdc: 20.0 GB, 20020396032 bytes
        255 heads, 63 sectors/track, 2434 cylinders
        Units = cylinders of 16065 * 512 = 8225280 bytes
        Disk identifier: 0x000c6487

            Device Boot      Start         End      Blocks   Id  System
        /dev/sdc1   *           1        2434    19551073+  8e  Linux LVM

        But I can't mount this one either using  " mount /dev/sdc1 -t
        ext3 /mnt/hdtest "

        It protests about the file type[?]. Perhaps lvm requires a
        different type?
