Setting up ZFS on LUKS

2018-03-05T11:21:09Z

Azarus: Add TODO

= Introduction =

This documentation describes how to set up Alpine Linux using ZFS with a pool that is located in an encrypted partition. To encrypt the partition the Device Mapper crypt (dm-crypt) module and Linux Unified Key Setup (LUKS) is used.

Note that you must install the <code>/boot/</code> directory on an unecrypted partition to boot correctly.

We'll be using the syslinux bootloader and traditional BIOS booting.

== Requirements ==

* An already installed Alpine on a medium other than the one you'll boot from, see [[Installation|official installation guide.]]
{{Note|We can't use the live environment from the installation isos, because we'll install the ZFS kernel module and that isn't possible with a read-only /boot (as provided by the iso).}}

== Hard Disk Device Name ==

The following documentation uses the <code>/dev/sda</code> device as installation destination. If your environment uses a different device name for your hard disk, use the corresponding device names in the examples.

= Setting up Alpine Linux Using ZFS on Top of a LUKS Partition =

To install Alpine Linux in a ZFS pool on top of a LUKS encrypted partition, you cannot use the [[Installation|official installation]] procedure. The installation requires several manual steps you must run in the Alpine Linux Live CD environment.

== Preparing the Installation Environment ==

Before you begin to install Alpine Linux on the medium you intend to boot from, prepare the installation you already have:

* Update the <code>apk</code> cache:

# apk update

* Install the following packages required to set up ZFS and LUKS:

# apk add haveged cryptsetup e2fsprogs syslinux zfs zfs-$(uname -r | rev | cut -d'-' -f1 | rev)
# modprobe zfs

* Optionally, start the <code>haveged</code> service for unpredictable random numbers used for encryption:

# rc-service haveged start

== Creating the Partition Layout ==

Linux requires an unencrypted <code>/boot/</code> partition to boot. You can assign the remaining space for the encrypted ZFS pool.

* Start the <code>fdisk</code> utility to set up partitions:

# fdisk /dev/sda

:* Create the <code>/boot/</code> partition:
::* Enter <code>n</code> → <code>p</code> → <code>1</code> → <code>1</code> → <code>100m</code> to create a new 100 MB primary partition.

:* Set the <code>/boot/</code> partition active:
::* Enter <code>a</code> → <code>1</code>.

:* Create the LUKS partition:
::* Enter <code>n</code> → <code>p</code> → <code>2</code> to start creating the next partition. Press <code>Enter</code> to select the default start cylinder. Enter the size of partition. For example, <code>512m</code> for 512 MB or <code>5g</code> for 5 GB. Alternatively press <code>Enter</code> to set the maximum available size.

:* To verify the settings, press <code>p</code>. The output shows, for example:
<pre>
Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 206847 204800 100M 83 Linux
/dev/sda2 206848 41943039 41736192 19.9G 83 Linux
</pre>
* Press <code>w</code> to save the changes.

* Optionally, wipe the LUKS partition with random values:

# haveged -n 0 | dd of=/dev/sda2

{{Note|Depending on the size of the partition, this process can take several minutes to hours.}}

== Encrypting the ZFS Partition ==

* To encrypt the partition which will later contain the LVM PV:

# cryptsetup luksFormat /dev/sda2

:{{Note|Alpine Linux uses the <code>en-us</code> keyboard mapping when prompting for the password to encrypt the partition at boot time. If you changed the keyboard map in the temporary environment, the password you enter during encrypting the partition in this step, may not match the password you will enter during the system boots.}}
: If you prefer setting an individual hashing algorithm and hashing schema:
:* To run a benchmark:

# cryptsetup benchmark

:* To encrypt the partition using individual settings, enter, for example:

# cryptsetup -v -c serpent-xts-plain64 -s 512 --hash whirlpool --iter-time 5000 --use-random luksFormat /dev/sda2

== Creating the filesystems ==

* Open the LUKS partition:

# cryptsetup open --type luks /dev/sda2 crypt

=== Creating the ZFS pool ===

# zpool create -o ashift=12 -O normalization=formD -O atime=off -m none -R /mnt -O compression=lz4 tank /dev/mapper/crypt

Meaning of the <code>zpool create</code> options:

{| cellpadding="5" border="1" class="wikitable"
|-
! Option
! Meaning
|-
| zpool create
| Creating the zpool
|-
| -o ashift=12
| 4K blocks
|-
| -O normalization=formD
| Set the default Unicode (UTF-8) normalization to 'formD'
|-
| -O atime=off
| Disabling updates to file access time. This reduces writes to disk, but might cause issues with mailers, like <code>mutt</code>.
|-
| -m none
| No mountpoint, as we'll handle this later.
|-
| -R /mnt
| Set the altroot to <code>/mnt</code>. It's like a temporary mountpoint for the pool.
|-
| -O compression=lz4
| Use lz4 compression for the pool. Is generally recommended.
|-
| tank
| The pool name. <code>tank</code> will be used in throughout this guide.
|-
| /dev/mapper/crypt
| The path to the block device ZFS will use.
|}

After completing this, confirm that the pool has been created:

# zpool status

Should return something like:
<pre>
pool: tank
state: ONLINE
scan: none requested
config:

NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 0
crypt ONLINE 0 0 0

errors: No known data errors
</pre>

=== Creating the required datasets ===

# zfs create -o mountpoint=none -o canmount=off tank/ROOT
# zfs create -o mountpoint=/ tank/ROOT/alpine

=== Creating optional datasets (feel free to add your own) ===

# zfs create -o mountpoint=/home tank/HOME
# zfs create -o mountpoint=/var/log tank/LOG

== Creating the <code>/boot</code> filesystem ==

# mkfs.ext4 /dev/sda1

== Mounting the <code>/boot</code> filesystem ==

* Create <code>/mnt/boot/</code> directory and mount the <code>/dev/sda1</code> partition in this directory:

# mkdir /mnt/boot/
# mount -t ext4 /dev/sda1 /mnt/boot/

== Installing Alpine Linux ==

In this step you will install Alpine Linux in the <code>/mnt/</code> directory, which contains the mounted file system structure.

* Install Alpine Linux:

# setup-disk -m sys /mnt/

: The installer downloads the latest packages to install the base installation. Additionally, the installer automatically creates the entries for the mount points in the <code>fstab</code> file (but we'll have to edit it manually later), which are currently mounted in the <code>/mnt/</code> directory.

: {{Note|The automatic writing of the master boot record (MBR) fails in this step. You will write the MBR later manually to the disk.}}

* To enable the operating system to decrypt the LUKS partition at boot time, create the <code>/mnt/etc/crypttab</code> file. Enter the following line into the file to decrypt the <code>/dev/sda2</code> partition using the <code>luks</code> module and map it to the <code>lvmcrypt</code> name:

crypt /dev/sda2 none luks

* Delete the zfs entries in <code>/mnt/etc/fstab</code> as ZFS mounts them automagically, your fstab should look like this:

UUID=6b4f2c9c-0a0f-4a8c-a73b-d2b47920ad6f /boot ext4 rw,relatime,stripe=4,data=ordered 0 2

* Edit the <code>/mnt/etc/mkinitfs/mkinitfs.conf</code> file and append the <code>cryptsetup</code> and <code>zfs</code> module to the <code>features</code> parameter:

features="ata base ide scsi usb virtio ext4 lvm <u>cryptsetup zfs</u>"

* Rebuild the initial RAM disk:

# mkinitfs -c /mnt/etc/mkinitfs/mkinitfs.conf -b /mnt/ $(ls /mnt/lib/modules/)

: The command uses the settings from the <code>mkinitfs.conf</code> file set in the <code>-c</code> parameter to generate the RAM disk. The command is executed in the <code>/mnt/</code> directory and the RAM disk is generated using the modules for the installed kernel. Without setting the kernel version using the <code>$(ls /mnt/lib/modules/</code>) option, <code>mkinitfs</code> tries to generate the RAM disk using the kernel version installed in the temporary environment, which can differ from the latest one installed by the <code>setup-disk</code> utility.

* Edit the <code>/mnt/etc/update-extlinux.conf</code> file, set the root ZFS dataset and append the following kernel options to the <code>default_kernel_opts</code> parameter:

root=tank/ROOT/alpine
default_kernel_opts="... <u>cryptroot=/dev/sda2 cryptdm=crypt rootfstype=zfs</u>"

: The <code>cryptroot</code> parameter sets the name of the device that contains the root file system. The <code>cryptdm</code> parameter sets the name of the mapping previously set in the <code>crypttab</code> file. The <code>rootfstype</code> option sets the root filesystem type to zfs.

* Because the <code>update-extlinux</code> utility operators only on the <code>/boot/</code> directory, temporarily change the root to the <code>/mnt/</code> directory and update the boot loader configuration:

# chroot /mnt/
# update-extlinux
# exit

: Ignore the errors the <code>update-extlinux</code> utility displays.

* Write the MBR to the <code>/dev/sda</code> device:

# dd bs=440 count=1 conv=notrunc if=/mnt/usr/share/syslinux/mbr.bin of=/dev/sda

== Unmounting the filesystems ==

* Unmount <code>/mnt/boot/</code>:

# umount /mnt/boot/

* Unmount all zfs filesystems:

# zfs unmount -a

* Close the <code>lvmcrypt</code> device:

# cryptsetup luksClose crypt

* Reboot the system:

# reboot

= Troubleshooting =

== General Procedure ==

In case your system fails to boot, you can verify the settings and fix incorrect configurations:

* [[#Preparing_the_Temporary_Installation_Environment|Prepare the temporary installation environment]]

* Load the ZFS kernel module:

# modprobe zfs

* [[#Mounting_the_File_Systems|Mount the file systems]]

# zpool import -R /mnt tank
# mount -t ext4 /dev/sda1 /mnt/boot

* Verify that you run the steps described in the [[#Installing_Alpine_Linux|Installing Alpine Linux]] section correctly. Update the configuration if necessary.

* [[#Unmounting_the_Volumes_and_Partitions|Unmount the volumes and partitions]]
