System with root device on LVM fails to boot after upgrade to SLES10 SP1

This document (3024507) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 10 SP1
SUSE Linux Enterprise Desktop 10 SP1


Root device "/" is a logical volume (LVM2)

After an upgrade from SLES10 GA to SLES10 Support Pack 1, the second stage instalation boot sequence hangs:

ERROR: Waiting for device /dev// to appear: ............not found -- exiting to /bin/sh


The problem is caused by a bug in mkinitrd that incorrectly matches EVMS/LVM devices.
Fix is included in mkinitrd-1.2-106.61

  1. Boot from DVD => Start Installation => "Boot Installed system"
  2. Download and install mkinitrd-1.2-106.61or later
  3. Rebuild initrd with lvm2 support:
    mkinitrd -f lvm2

Additional Information

It might be necessary to run depmod in some cases before building the new initrd.
For autoyast installation problems with root device on LVM see TID#3523475 Auto installation with LVM on root fails.
