Dear community Something changed since crux-2.3. ;-) Hopefully. But with the good old crux-2.3 boot-cd, I can boot a server and the md-devices were autodetected and binded correctly. Crux-2.3 md, scsi, sata compiled into kernel -> works Crux-2.4, Crux-2.5: kernel modular, initramfs -> no autodetect anymore Or is this a difference between mdev and udev ? I tried also a selfbuild kernel with all relevant parts buildin. But this doesn't help. Short google-session brought some results: "... kernel autodetect is correspondingly deprecated." http://linux-raid.osdl.org/index.php/RAID_Boot They solved it with an initramfs and mdadm.conf. But this is the wrong way for a live-cd. I attached 2 patches for "manuell auto-detecting" raids within the squashfs-environment. Is this the "right" way for crux ? Any help would be appreciated. best regards Falk Hamann -- Falk Hamann, IT T +49-7191-9669-242, F +49-7191-9669-6242, Falk.Hamann@dbaudio.com www.dbaudio.com d&b audiotechnik GmbH, Eugen-Adolff-Str. 134, 71522 Backnang, Germany Geschäftsführer: Frank Bothe, Markus Strohmeier Finanzen: Kay Lange; Marketing: Simon Johnston; Vertrieb: Peter Tongue Sitz: Backnang; Amtsgericht - Registergericht - Stuttgart, HRB 725789 --- /tmp/squashfs-root/opt/bin/raids.sh.empty 1970-01-01 01:00:00.000000000 +0100 +++ /tmp/squashfs-root/opt/bin/raids.sh 2008-11-28 15:09:55.000000000 +0100 @@ -0,0 +1,28 @@ +#!/bin/bash +partitions=`cat /proc/partitions |sed "2d;s/\(\s*\S*\)\{3\}\s*\(\S*\)/\2/;"` +uuids="" +for dev in $partitions;do + hdd=`echo $dev | sed -e 's#\([a-z]\+\)\([0123456789]\+\)#/dev/\1#'` + nr=`echo $dev | sed -e 's#\([a-z]\+\)\([0123456789]\+\)#\2#'` + if [ ! -b $hdd ];then continue;fi + id=`sfdisk --id $hdd $nr` + if [ "XXX$id" == "XXXfd" ];then + uuid=`mdadm --examine /dev/$dev|grep UUID|sed "s/.*UUID\s*:\s*\(\S*\)/\1/"` + minor=`mdadm --examine /dev/$dev|grep "Preferred Minor"|sed "s/.*Preferred Minor\s*:\s*\(\S*\)/\1/"` + uuids="$uuids $uuid" + if [ -e /sys/block/md${minor}/md/array_state ];then + status=`cat /sys/block/md${minor}/md/array_state` + case "$status" in + clean) + echo md$minor already started and clean + ;; + *) + echo Status of md$minor is "$status".
