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

Environment

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

Situation

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

Resolution

The problem is caused by a bug in mkinitrd that incorrectly matches EVMS/LVM devices.

Fix is included in mkinitrd-1.2-106.61

Workaround:

Boot from DVD => Start Installation => "Boot Installed system"
Download and install mkinitrd-1.2-106.61or later
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.
