Re: booting from software-RAID1 with debian on nslu2
Hi,
I've created a temporary fix that works in my case. I have make a copy
of one of the scripts in the initramfs:
cp /usr/share/initramfs-tools/scripts/local /etc/initramfs-tools/
scripts
and I have added one line to the copy, resulting in the following
file:
----------------------------
# Local filesystem mounting -*- shell-script -*-
# Parameter: device node to check
# Echos fstype to stdout
# Return value: indicates if an fs could be recognized
get_fstype ()
{
local FS FSTYPE FSSIZE RET
FS="${1}"
# vol_id has a more complete list of file systems
if [ -x /lib/udev/vol_id ]; then
FSTYPE=$(/lib/udev/vol_id -t "${FS}" 2> /dev/null)
else
eval $(fstype < "${FS}" 2> /dev/null)
fi
RET=$?
if [ -z "${FSTYPE}" ]; then
FSTYPE="unknown"
fi
echo "${FSTYPE}"
return ${RET}
}
# Parameter: Where to mount the filesystem
mountroot ()
{
[ "$quiet" != "y" ] && log_begin_msg "Running /scripts/local-
top"
run_scripts /scripts/local-top
[ "$quiet" != "y" ] && log_end_msg
# If the root device hasn't shown up yet, give it a little
while
# to deal with removable devices
if [ ! -e "${ROOT}" ] || ! $(get_fstype "${ROOT}" >/dev/null);
then
log_begin_msg "Waiting for root file system..."
# Default delay is 180s
if [ -z "${ROOTDELAY}" ]; then
slumber=180
else
slumber=${ROOTDELAY}
fi
if [ -x /sbin/usplash_write ]; then
/sbin/usplash_write "TIMEOUT ${slumber}" ||
true
fi
slumber=$(( ${slumber} * 10 ))
while [ ! -e "${ROOT}" ] \
|| ! $(get_fstype "${ROOT}" >/dev/null); do
/bin/sleep 0.1
/sbin/mdadm --assemble --run --auto=yes /dev/
md1 # ADDED THIS LINE, TEMPORARY FIX
slumber=$(( ${slumber} - 1 ))
[ ${slumber} -gt 0 ] || break
done
if [ ${slumber} -gt 0 ]; then
log_end_msg 0
else
log_end_msg 1 || true
fi
if [ -x /sbin/usplash_write ]; then
/sbin/usplash_write "TIMEOUT 15" || true
fi
fi
# We've given up, but we'll let the user fix matters if they
can
while [ ! -e "${ROOT}" ]; do
echo "ALERT! ${ROOT} does not exist. Dropping to a
shell!"
echo " Check your root= boot argument (cat /proc/
cmdline)"
panic " Check for missing modules (cat /proc/modules),
or device files (ls /dev)"
done
# Get the root filesystem type if not set
if [ -z "${ROOTFSTYPE}" ]; then
FSTYPE=$(get_fstype "${ROOT}")
else
FSTYPE=${ROOTFSTYPE}
fi
[ "$quiet" != "y" ] && log_begin_msg "Running /scripts/local-

run_scripts /scripts/local-premount
[ "$quiet" != "y" ] && log_end_msg
if [ ${readonly} = y ]; then
roflag=-r
else
roflag=-w
fi
# FIXME This has no error checking
modprobe ${FSTYPE}
# FIXME This has no error checking
# Mount root
mount ${roflag} -t ${FSTYPE} ${ROOTFLAGS} ${ROOT} ${rootmnt}
[ "$quiet" != "y" ] && log_begin_msg "Running /scripts/local-

run_scripts /scripts/local-bottom
[ "$quiet" != "y" ] && log_end_msg
}
--------------------
The original file is part of version initramfs-tools-0.88. The added
line makes sure that /dev/md1 is assembled when usb disks become
available. This is the output of the boot process at the serial
