Hello,
looks like i managed to force fai to build working initramfs.
modified:
/srv/fai/config/scripts/CENTOS/30-mkinitrd
# call dracut for CentOS 7
if [ -f $target/usr/sbin/dracut ]; then
# add filesystem driver into initrd
ainsl -av /etc/dracut.conf.d/fai.conf 'filesystems+="ext4"'
+ ainsl -av /etc/dracut.conf.d/fai.conf 'add_dracutmodules+="dm lvm"'
$ROOTCMD dracut -v --kver $version --force
fi
still it doesn't explain why dracut was not picking those modules
automatically.
best regards,
Antanas Masevicius
