Normal boot:
pvscan -- total: 21 [211.14 GB]
You need to sort out what disks/partitions that are not accessible
from the rescue disks... You can also try ungrading LVM as 1.01 is
quite old...

> I am trying to mount my LVM partitions manually after booting into a

> Here are the details of what I am doing:
> Setup:
> boot partition /dev/hda2 type Linux with Ext2
> root partition /dev/hda3 type Linux with Reiserfs
> other partitions /dev/hda[6-16] type LVM
> /hdb[6-15] type LVM
> One volume group exists called "system" comprising all the above LVM partitions
> LVM version is 1.0.1-rc2(30/08/2001)
> Rescue boot procedure:
> 1. Booting rescue system (SuSE 7.3 rescue disk).
> 2. Loading LVM and Reiser modules from floppy. These are nor included on
> the rescue disk.
> 3. Mounting HD root-partition /dev/hda3 on /mnt to get access to the
> LVM programs in what has now become /mnt/sbin.
> 4. Linking /mnt/lib/* from /lib since the LVM programs need more
> libraries than those included in rescue the system.
> 5. Freeing space on /. I have noticed that my normal root-partition
> /dev/hda3 holds a file called /etc/lvmtab.d/system ("system" is the
> name of my volume group) which is 256K so I expect the
> rescue-system RAM-disk will need at least that amount of free space.
> 6. Running vgscan and vgchange -ay. Vgscan reports the creation of
> /etc/lvmtab" and "/etc/lvmtab.d but doesn't report finding any
> volume groups. Vgchange reports that there are no volume groups to
> activate. Here is the output:
> vgscan -- removing "/etc/lvmtab" and "/etc/lvmtab.d"
> vgscan -- creating empty "/etc/lvmtab" and "/etc/lvmtab.d"
> vgscan -- reading all physical volumes (this may take a while...)
> vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
> vgscan -- WARNING: This program does not do a VGDA backup of your volume group
> vgchange -- locking logical volume manager
> vgchange -- finding all volume group(s)
> vgchange -- no volume groups found
> Here is the output of some commands run in the rescue system:
