I'm using this /srv/fai/config/class/99-disklist.sh based on the one
linked by Thomas:
-8<--
#! /bin/bash
mydisks() {
find $* -type l -printf "%f %l\n" | grep -Pv
'^md|-part\d|^wwn-|^nvme-eui|^nvme-nvme' | egrep '^scsi|^ata|^nvme' |
sed -e 's#.*/##g'| tr '\n' ' '
}
# This is really important, because we use shell globbing for creating
the list of disks
cd /dev/disk/by-id || echo Cannot get disk information
filter='nvme*'
# can not use $0: script is sourced, not run explicitly !
datadir=$FAI/class/99-disklist.d
echo "**** Testing $datadir/$HOSTNAME"
if [ -f $datadir/$HOSTNAME ] ; then
# Source host-specific list. Can define a new list or override filter
. $datadir/$HOSTNAME
fi
if [ -z $newlist ]; then
echo "newlist is empty, filter=$filter"
newlist=$(mydisks $filter )
fi
if [ -n "$newlist" ]; then
echo New disklist in 99-disklist.sh: $newlist
echo "disklist=\"$newlist\" # $0" >> $LOGDIR/additional.var
fi
-8<--
Then I can place a per-host script under
/srv/fai/config/class/99-disklist.d/hostname to modify the list for
'hostname':
-8<--
#!/bin/bash
. /usr/lib/fai/subroutines
newlist=$(smallestdisk)
-8<--
I'll probably extend it a bit to also look for classes.

Hello,
hope it's the correct list.
OS ubuntu 22.04 LTS or higher
is it possible to choose automatically the smaller disk?
In my case there is a Dell Server with RAID-Controller, configured:
sda = ca. 5 TB SSD for data - during install shall be not
touched/formatted...
sdb = ca. 900 GB SAS = shall be root and OS installed
In other cases, sda = ca. 300 TB (data) and sdb ca. 500 GB => for OS.
Thanks,
Harald
