I have found a intresting thing for using RAID with setup storage.
Also a RAID 1 with one drive is allowed with setupstorage.
<pre>
disk_config disk1 bootable:1
primary  -              50    -        -
logical  -              800    -        -
logical  -              3000-  -        -
disk_config raid
raid1        /boot  disk1.1            ext2        rw,errors=remount-ro
raid1        swap    disk1.5            swap        sw
raid1        /      disk1.6            ext3        rw
</pre>
After installation you can expand it with:
<pre>
mdadm --grow -n 2
</pre>
to a real raid. Then you must rebuild it like one disk has failed.
------------
This use of softupdate may be used if you install from fai-cd and
your space is limit. After installing a base host you can softupdate
from a fai server. Also for some other cases this may be a good solution.
class/51-host-add-softupdate-classes
<pre>
#! /bin/bash
# set -xv
# For debugging add classes in /var/lib/fai/FAI_CLASSES
if [ "$action" = "softupdate" ] ; then
  (ifclass DEMO) || echo "DEMO"
fi
exit 0
</pre>
Mini Helper:
<pre>
#!/bin/bash
#
# Pfad change for FAI config space 
FAICONFIG=/srv/fai/config/files
PATHVAR=$1
CLASS=$2
[ $2 ] || CLASS=`hostname -s`
mkdir -p $FAICONFIG$PATHVAR
cp $PATHVAR $FAICONFIG$PATHVAR/$CLASS
</pre>

Hello,

I am Andreas.

These are some ideas, if you think they need a other location feel free to move. But leave a short message that I can remove it from this page.
