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

> boot from my harddisk LVM works just fine. Notice the output from

> system /dev/hda16 is not there. I don't know if that is related to my
> problem, though.

> 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
