Converting the root filesystem to ReiserFS on LVM...

[Madison Kelly]

Hi all,

   I am officially stumped... I have tried two rescue discs (SysRescCD 
and PLD Rescue) as well and my Fedora Core 1 install disk using 'linux 
rescue' in an attempt to backup the FC1 root partition so that I can 
reformat it as ReiserFS and then restore it.

   When I use the FC1 cd I can't unmount '/mnt/sysimage' which is seen 
as the LVM device '/dev/VG00/LV00', it keeps saying the device or 
resource is busy (despite being out of the directory and running off the 
CD). When I try to boot off either rescue CD 'root' isn't mounted but 
then I can't find the darn LVM partitions (and yes I made sure that the 
rescue CDs supported LVM and ReiserFS).

   Under Fedora the devices I need to mount are on:

/dev/VG00/LV00 = '/' (currently ext3)
/dev/VG00/LV01 = '/backup' (reiserfs)
/dev/VG00/LV02 = '/snapshot' (reiserfs)

   Under the two rescue CDs though there is no '/dev/VG00...'. Where 
would I find those partitions? I tried looking under '/dev/' but the 
only thing relevant I could find was '/dev/ide/host0/bus0/target0/lun0/' 
and there was no sign of the LVM partitions (nor under variants like 
'bus1', etc.).

   Any help would be greatly appreciated!

Madison
