I have been bookmarking sites like mad and apparently chose the wrong one... Here is my linuxrc inside the initrd image (this is the one based off of the evms initrd I found on the web, since it seemed the most complete). Please note that I still can't get the "/bin/ash" command to work properly, though I'm working on it. I did put in the /dev/tty* and /dev/pt* nodes into the initrd image, but still no luck. -------- CUT -------- gweber@windforce:/tmp/test$ more linuxrc #!/bin/sh /bin/mount /proc echo /sbin/modprobe > /proc/sys/kernel/modprobe if test ! -e /dev/.devfsd ; then set -e MAJOR=$(/bin/sed -n 's/^ *$[0-9]\+$ \+misc$/\1/p' /proc/devices) MINOR=$(/bin/sed -n 's/^ *$[0-9]\+$ \+device-mapper$/\1/p' /proc/misc ) if test -n "$MAJOR" -a -n "$MINOR" ; then /bin/mknod --mode=600 /dev/mapper/control c $MAJOR $MINOR fi fi /sbin/lvm vgchange --ignorelockingfailure -P -a y /bin/ash /bin/umount /proc -------- CUT -------- Also note that I have tried "root=0a3f", "root=fe00", and "root=/dev/vg00/root"... the major/minor numbers are listed here (from /dev/hda4 "temporary install" root): -------- CUT -------- gweber@windforce:~$ ls -l /dev/mapper crw------- 1 root root 10, 63 Oct 27 13:34 control brw------- 1 root root 254, 1 Oct 22 08:56 vg00-home brw------- 1 root root 254, 0 Oct 22 08:56 vg00-root brw------- 1 root root 254, 3 Oct 29 08:21 vg00-tmp brw------- 1 root root 254, 4 Oct 29 08:21 vg00-usr brw------- 1 root root 254, 2 Oct 29 08:21 vg00-var -------- CUT -------- In order to (try to) make this work, I did copy all the "missing" binaries, libs, and dev nodes into the evms initrd image. I would supply that listing, but it would be quite long... Here is my menu.lst from grub. I've been testing with grub just so that I could enter changes at boot time instead of running "lilo" all over the place. -------- CUT -------- gweber@windforce:/tmp/test$ more menu.lst # Author: Luis R.

What you find there is modified Mandrake rpm to support lvm2 in Mandrake Linux 9.2/cooker, and has not been tested with anything different than that. > to see what I could find out.
