I tried to write a similar hook, but it never seemed to get executed(!) Are these hooks pre-install ones? What special magick should I chant to get them running? :) I have Mr. Vilain's script from: http://web.archive.org/web/20040102221743/http://vilain.net/linux/fai/ With IDE_RAID1 modified to suit my needs. I also had the change the drive detection code in setup_harddisks. One problem is that although I boot with LILO lilo doesn't even get installed. Any ideas why? The other is, why isn't that setup_harddisks merged into mainline FAI? Or is it but not documented? Seems to me like this all-raid1 setup would be the most used application of FAI, since it's such a task to install manually... >shell.log:Syntax error at or above line 2 in file '/etc/lilo.conf' >shell.log:DEFAULT/S10 FAILED with exit code 1. What does it look like there? I have added raid-extra-boot="/dev/hda,/dev/hdc" in my S10 if ifclass SOFTRAID1 but still no lilo is installed. >Setting up kernel-image-2.6.8-1-686-smp (2.6.8-5) ... >/usr/sbin/mkinitrd: RAID support requires raidtools2 Bizarro, iirc my setup installs raidtools2 just by itself. In DEFAULT or somesuch. I have to say here that this is something of the lowest priority, so I get to advance my FAI toy maybe a few hours per week, which makes this all the more interesting ;) >partition.ATA_RAID file: I added my questions in form of comments ;) >#!/bin/bash -x > >#**************************************************** ># build a raid array for filesystems >#**************************************************** > ># let FAI partition disks and then we'll modify >task_partition # Is this supposed to be one line? ># get list of partitions >disks="/dev/sda /dev/sdc" >partitions=$(sfdisk -l $disks|grep "^/dev/sd[a-z][0-9]"|cut -d" " -f1) # The line I edited in Mr. Vilain's script looked like this, but I # had /dev/hda /dev/hdc as disks in a similar sfdisk magic. ># change partition type to raid >for partition in [EMAIL PROTECTED]; do > dev=$(echo $partition | tr -d '[:digit:]') > part=$(echo $partition | tr -cd '[:digit:]') > id=$(sfdisk --print-id $dev $part) > case ${id} in > 82) sfdisk --change-id $dev $part fd ;; > 83) sfdisk --change-id $dev $part fd ;; > esac >done > ># partition mirror disks >sfdisk -d /dev/sda | sfdisk /dev/sdb >sfdisk -d /dev/sdc | sfdisk /dev/sdd # Took me a second reading to see that you use the partitions # that you have already, right? ># create raid array for each partition >mdadm -C /dev/md1 -v -R -f -l1 -c128 -n2 /dev/sd[ab]1 # / >mdadm -C /dev/md5 -v -R -f -l1 -c128 -n2 /dev/sd[ab]5 # swap >mdadm -C /dev/md6 -v -R -f -l1 -c128 -n2 /dev/sd[ab]6 # /var >mdadm -C /dev/md7 -v -R -f -l1 -c128 -n2 /dev/sd[ab]7 # /tmp >mdadm -C /dev/md8 -v -R -f -l1 -c128 -n2 /dev/sd[ab]8 # /usr >mdadm -C /dev/md9 -v -R -f -l1 -c128 -n2 /dev/sd[ab]9 # /opt >mdadm -C /dev/md10 -v -R -f -l1 -c128 -n2 /dev/sd[ab]10 # /local >mdadm -C /dev/md11 -v -R -f -l1 -c128 -n2 /dev/sd[cd]1 # /export > ># create filesystems >arrays=$(cat /proc/mdstat|grep "^md[0-9]"|cut -d" " -f1) >for array in [EMAIL PROTECTED]; do > echo y | mkreiserfs -f -q /dev/${array} >done > ># create swap >mkswap /dev/md5 > ># create /etc/fstab >cat > ${LOGDIR}/fstab << EOF ># /etc/fstab: static file system information. >#<file sys> <mount point> <type> <options> <dump> <pass> >/dev/md1 / reiserfs defaults 0 1 >/dev/md5 none swap rw 0 0 >none /proc proc defaults 0 0 >/dev/md10 /local reiserfs defaults 0 2 >/dev/md9 /opt reiserfs defaults 0 2 >/dev/md7 /tmp reiserfs defaults 0 2 >/dev/md8 /usr reiserfs defaults 0 2 >/dev/md6 /var reiserfs defaults 0 2 >/dev/md11 /export reiserfs defaults 0 2 >EOF > ># create new disk variables >cat > $diskvar << EOF >BOOT_DEVICE=/dev/sda >ROOT_PARTITION=/dev/md1 >BOOT_PARTITION=/dev/md1 >SWAPLIST="/dev/md5" >EOF > >. $diskvar > >skiptask partition # Couldn't you do partition to automagically partition the sda and # sdc for sdb and sdd? # Place this hook after partition? Otherwise this seems like my initial approach, but yeah, now I have the bigger task of having an unbootable system.. I never got it to boot even with a vanilla FAI example installation :P I boot with (the relevant fai options): FA I_ACTION=install FAI_FLAGS=verbose,sshd,createvt,syslogd,debug LILO SOFTRAID1 MBR Is there something obviously wrong here? I can't remember if package_config/DEFAULT had this by default but this is a snippet from mine: PACKAGES install GRUB grub lilo- PACKAGES install LILO lilo grub- Thanks a million for any comments/helps/anything you have! :) -- mjt
