| Hi there,
At this moment, I have following configuration.
I would like to recover data from hda3 (which was a fedora 4 vloumn).
I now install a new core without lvm.
hda2 as boot.
hdb10 as root
hdb7 as home
hdb8 as opt
Disk /dev/hda: 60.0 GB, 60022480896 bytes
255 heads, 63 sectors/track, 7297 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 3824 30716248+ 7 HPFS/NTFS
/dev/hda2 3825 3837 104422+ 83 Linux
/dev/hda3 3838 7297 27792450 8e Linux LVM
Disk /dev/hdb: 160.0 GB, 160041885696 bytes

Sid,
1) vgscan
2) vgdisplay -v|more
{write down the volumegroup(s) and the logical volumegroups}
3) mount each logicalvolume on a mountpoint
4) if you want to keep using the logical volumes, add them to your
/etc/fstab like the /dev/hda2, /dev/hdb10, /dev/hdb7 and /dev/hdb8
entries. The devicefile for a logical volume is of the form:
/dev/Volgroup00/LogVol00
Kind regrads,
