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.
