14.04 software raid and encryption

I used this as a starting point

http://askubuntu.com/questions/505446/how-to-install-ubuntu-14-04-with-raid-1-using-desktop-installer

I did my own pairs of /boot and / partions on my real disks sda and sdb, then installed mdadm and created the md0 and md1 raids from the command line then ran ubiquity -b

(my /boot is not encrypted, but / is)

used md1 as a encrypted volume which I then mounted as /

#I then used the first guide’s steps to chroot into the new disk, and setup grub
grub-install /dev/sda
grub-install /dev/sdb

#but added steps from
http://blog.asiantuntijakaveri.fi/2014/12/headless-ubuntu-1404-server-with-full.html

to make sure the initrd knew how to mount my encrypted /

#these steps help initrd find my software raid
mkdir -p /dev/md
ln -s /dev/md0 /dev/md/0
ln -s /dev/md1 /dev/md/1
ln -s /dev/md0p1 /dev/md/0p1
ln -s /dev/md1p1 /dev/md/1p1

#make grub easier to deal with
/etc/default/grub (change silent to vervbose, comment out the HIDDEN lines, set the bootwait=10, nosplash, bootdegraded=true

/etc/grub.d/10_linux (set quickboot and quietboot to zero)

add some things to the end of /etc/default/grub

GRUB_TERMINAL_OUTPUT=console
GRUB_TERMINAL=console
GRUB_GFXPAYLOAD=text
GRUB_GFXPAYLOAD_LINUX=keep

#tweaks to get the crypto stuff into initrd
echo “CRYPTSETUP=y” >> /etc/initramfs-tools/initramfs.conf

sed -i -e’s|^setup=”no”$|setup=”yes”|g’ /usr/share/initramfs-tools/hooks/cryptroot

#then rebuild initrd
update-initramfs -c -k all

#then confirm that your initrd has the crypt stuff
lsinitramfs /boot/initrd.img-3.13.0-40-generic | grep cryptroot
lsinitramfs /boot/initrd.img-3.13.0-40-generic | grep cryptsetup

# Update grub.cfg
update-grub

then exit the chroot and umount and reboot
