FreeBSD: gptzfsboot: No ZFS pools located, can’t boot on FreeBSD 11-RELEASE

Last time (a few years back) when I tried to install FreeBSD with zfs on my HP Pavilion dm3-1130us notebook, I got the following error message during the boot: gptzfsboot: error 66 lba 48 error 72 gptzfsboot: error 66 lba 0 gptzfsboot: error 66 lba 1 gptzfsboot: No ZFS pools located, can't boot.

I searched around for a solution but couldn't find any so I gave up on FreeBSD.

Years after, meaning recently, I gave FreeBSD 11-RELEASE a new shot, hoping that zfs boot up problem was resolved by now. *BAM* I got the same error after installing it with zfs. For desperation, I searched again and again. Tried building partition table manually, updating bootcode after the installation, etc... But nothing worked... I even tried TrueOS (FreeBSD with zfs and more) but got the same problem after the installation. Sob...

But finally, I found a solution (sort of)!!!

Here is what I tried. I don't think the installation medium makes difference but I used a USB boot image.

The information in this site is the result of my researches in the Internet and of my experiences. This information below is solely used for my purpose and may not be suitable for others.

Step 1) Download the FreeBSD memstick image. Find the latest release version (as of this writing, it's 11.0) from the freebsd.org ftp site.

Step 2) dd the memstick image to a USB memory stick. The USB device name could be different depending on which OS you are using, but for FreeBSD, I read somewhere that said you need to use FreeBSD to make a bootable USB memory stick. So, I installed FreeBSD 11-RELEASE with UFS and ran the command: # dd if=FreeBSD-11.0-RELEASE-amd64-memstick.img of=/dev/da0 bs=1M conv=sync

Step 3)Reboot with the USB memory stick inserted. Leave the USB memory stick attached to the notebook, rebooted the system. FreeBSD will boot and it'll present with three options; Install, Shell or Live CD. I chose Install.

Step 4) Install the system but at the partitioning, choose Auto ZFS:

Here is the zfs configuration:

Step 5) Go through the rest of the installation until it asks you for the last manual configuration. Select Yes to update gptzfsboot and bootdcode:

Step 6) Get the updated gptzfsboot_hp from the FreeBSD Bugzilla. The url is listed in Allan Jude at Comment 29. If you are not configured its networking, enable dhcp client: # dhclient re0

Then download gptzfsboot_hp by fetching from the location # fetch --no-verify-peer http://trooper.hml3.scaleengine.net/gptzfsboot_hp

Step 7) Rename gptzfsboot_hp to gptzfsboot and move it to /boot.

Step 8) Update the bootcode. Make sure you are using /boot/pmbr for the GPT partition type: # gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0

Step 9) Make sure the partition scheme and it's for the ada0 disk. Occasionally, its disk ID is changed to something like diskid/DISK-.... If this happens, use that disk name/id instead of ada0 at the Step 8.

Step 10) Reboot the system.

After the reboot, you would see the prompt for GELI Passphrase. However, this solution solved the boot up problem with ZFS. I still see the error 66 with lba: gptzfsboot: error 66 lba 48 error 72 gptzfsboot: error 66 lba 0 gptzfsboot: error 66 lba 1 GELI Passphrase for disk0p3:

After entering GELI passphrase correctly, voilĂ , you'll see the login prompt!

That's all!

Installing Arch Linux: LVM on top of an encrypted partition [[UPDATED]]

Years back, I was using Arch Linux on my notebook but gave up at some point after upgrading Arch Linux made my notebook unbootable. After some distro hoppings, I settled down with Debian Linux and it has been my friend since then. But now, out of a whim, I decided to give another try on Arch.

I'll be installing Arch Linux on the same notebook and I wanted the encryption on a disk/partition like before. I looked around some options from the Arch Linux Wiki. I read up on LVM on LUKS, LUKS on LVM, and Plain dm-crypt and decided to go with LVM on LUKS again. One of benefits for LUKS on LVM is that it can have encrypted volumes span multiple disks. It's nice but I don't need it since there is only one disk for the notebook. Plain dm-crypt can encrypt an entire disk and this is nice and ideal but having a USB flash memory around is a bit overkill for me. So, I'll stick with LVM on LUKS again.

I then followed my old post, Installing Arch Linux: LVM on top of an encrypted partition. What do you know? The information on that page was not wrong but was a bit confusing or hard to follow (not to mention about the number of typos. Sheesh!). So, I decided to re-do the whole steps, including the base installation of Arch Linux on LVM. Most of the information here will be duplicates from old one but please bare with me.

Information below is gathered mostly from the Arch Linux Wiki page and changed here and there for my liking. This information below is solely used for my purpose and may not be suitable for others.

Erasure of the Hard Disk:

Information (data) on a Hard Drive is written in chunk here and there. Re-partitioning or reformatting a disk does not really removes (erase) the data. It merely remove the system structure that used to identify where the original data was located. This leaves the actual data on a disk.

To securely erase a disk, you could either:

  • Fill with zeros
  • Fill with random bits

Both methods overwrite data on a disk but the first one fill with zero's leaving easily (to some extent) identify where the encrypted data ends. So, I follow the second method. # dd if=/dev/urandom of=/dev/<drive> bs=1M Just to be warned, this takes a long, long time.

Partitioning a Disk:

There is a way to encrypt the /boot partition with GRUB (for details, see Pavel Kogan's blog), but for simplicity, I'll stick with having the /boot partition separated from the encryption and LVM. # fdisk /dev/sda

Partition Layout:
/dev/sda1 -> /boot (bootable) - 300MB should be enough.
/dev/sda2 -> LVM (8e) - the rest of the disk

Configuring LUKS:

cryptsetup is used to interface with LUKS for formatting, mounting and unmounting encrypted partition.

First make sure the device mapper kernel module is installed: # modprobe dm-mod

Then format it as an encrypted LUKS partition: # cryptsetup --cipher aes-xts-plain64 --key-size 512 --hash sha512 luksFormat /dev/sda2

  • --cipher: defines the cipher type
  • --key-size: defines the key size
  • --hash sha512: hash algorithm used for key derivation.

It looks like AES cipher in XTS mode (XTS-AES) is most popular these days.

Unlocking/Mapping LUKS partition with the Device Mapper:

To access the encrypted volume, It needs to be unlocked. # cryptsetup open --type luks /dev/sda2 lvm


Create a physical volume (encrypted volume) and a group volume. # lvm pvcreate /dev/mapper/lvm # lvm vgcreate lvmvg /dev/mapper/lvm

Create logical volumes on this new volume group. # lvm lvcreate -L 10G -n root lvmvg # lvm lvcreate -L 500M -n swap lvmvg # lvm lvcreate -l 100%FREE -n home lvmvg

Format the filesystems on each logical volume. # mkfs.ext4 /dev/mapper/lvmvg-root # mkfs.ext4 /dev/mapper/lvmvg-home # mkswap /dev/mapper/lvmvg-swap

Mount the filesystems. # mount /dev/mapper/lvmvg-root /mnt # mkdir /mnt/home # mount /dev/mapper/lvmvg-home /mnt/home # swapon /dev/mapper/lvmvg-swap

Prepare the boot partition. # mkfs.ext2 /dev/sda1 # mkdir /mnt/boot # mount /dev/sda1 /mnt/boot

Configure Wireless Network:

Network connection needs to be configured before the installation can take a place. Since my notebook uses WiFi, I need to configure wireless network.

Check for the network interface and whether udev has loaded the driver. # iwconfig -------------------- eth0 no wireless extensions. lo no wireless extensions. wlan0 IEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=14 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:on

It looks like wlan0 is available.

Interface activation:

Not required for mine but here is how to activate # ip link set wlan0 up

Access point discovery:

I know my network information like ESSID, Encryption key, etc..., but here is how to list available access points # iwlist wlan0 scan | less

Or, for the new netlink interface # iw dev wlan0 scan | less

Association to the access point

Now a configuration file, /etc/wpa_supplicant.conf, needs to be created for my access point. # vi /etc/wpa_supplicant.conf -------------------- ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel eapol_version=1 ap_scan=1 fast_reauth=1

These options are explained in /etc/wpa_supplicant/wpa_supplicant.conf

Append the passphrase and PSK to the file # wpa_passphrase SSID_NAME "PASSPHRASE" >> /etc/wpa_supplicant.conf

Manual connection:

The WiFi interface should be up by the earlier command ip link set wlan0 up, so now tell wpa_supplicant the driver (wext - Linux Wireless EXTensions), the SSID specified in /etc/wpa_supplicant.conf and the wireless interface. # wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf

  • -B : Run in the background
  • -D : Driver information. Default is WEXT
  • -i : Wireless interface
  • -c : Configuration file

Request an IP address to DHCP server. # dhcpcd wlan0

Check assigned IP address. # ip addr show wlan0 wlan0: mtu 1500 qdisc mq state UP qlen 1000 link/ether 00:00:00:00:00:00: brb ff:ff:ff:ff:ff:ff inet brb scope global wlan0 inet6 fe80::ffff:ffff:ffff:ffff/64 scope link valid_lft forever preferred_lft forever

Select installation mirror:

Before installing, you may want to edit /etc/pacman.d/mirrorlist such that your preferred mirror is first. This copy of the mirrorlist will be installed on your new system by pacstrap as well, so it's worth getting it right.

Install the base system and other package groups:

The base system is installed using the pacstrap script. pacstrap is a script that installs packages to the specified new root directory. If no packages are given, pacstrap defaults to the "base" group.

Required X Window Systems packages for openbox will be installed in post-installation configuration.

The system uses wireless network, so install the required wireless network packages. # pacstrap /mnt base base-devel wireless_tools wpa_supplicant wpa_actiond


Let's configure the primary configuration files.

Generate an fstab file:

The fstab file contains static filesystem information. It defines how storage devices and partitions are to be mounted and integrated into the overall system. It is read by the mount command to determine which options to use when mounting a specific device or partition.

Check the resulting file afterwards, especially watch for the swap entry. # genfstab -p /mnt >> /mnt/etc/fstab # vi /mnt/etc/fstab -------------------- ... /dev/mapper/lvm-swap none swap defaults 0 0

Chroot into the system (Change root into the new system):

# arch-chroot /mnt

Editing /etc/rc.conf:

/etc/rc.conf is the configuration file for Arch's initscripts. Some of options in this file has been obsolete and they now have own configuration files (ex: hostname, etc...). /etc/rc.conf still configures daemons to start during boot-up and some networking and storage information.

Since LVM is used on this system, I need to enable it so that the kernel knows about it.

# vi /etc/rc.conf -------------------- USELVM="yes"


Configuring hostname requires updating two files, /etc/hostname and /etc/hosts

Add hostname in /etc/hostname # cat > /etc/hostname archy64 ^D

Add hostname in /etc/hosts # vi /etc/hosts -------------------- localhost.localdomain localhost archy64 ::1 localhost.localdomain localhost archy64

Console fonts and keymap:

The console, meaning a terminal running with no X Window System, uses the ASCII character set as the default.

A console font is limited to either 256 or 512 characters. The fonts are found in /usr/share/kbd/consolefonts/.

Keymaps, the connection between the key pressed and the character used by the computer, are found in the subdirectories of /usr/share/kbd/keymaps/ # cat > /etc/vconsole.conf KEYMAP=us FONT= FONT_MAP= ^D

  • KEYMAP - the default (us) is ok
  • FONT - the default (blank) is ok
  • FONT_MAP - the default (blank) is ok


Available time zones and subzones can be found in the /usr/share/zoneinfo/<Zone>/<SubZone> directories.

Create a symlink /etc/localtime to zone file. # ln -s /usr/share/zoneinfo/US/Eastern /etc/localtime


Choose the locale(s) from /etc/locale.gen and uncomment them. # vi /etc/locale.gen -------------------- en_US.UTF-8 UTF-8 -------------------- # locale-gen

Setting up system-wide locale:

# cat > /etc/locale.conf LANG=en_US.UTF-8 LC_TIME=en_US.UTF-8 ^D

Set the LANG variable for the ramdisk creation # export LANG=en_US.UTF-8

Hardware clock time:

It's recommended to use UTC. # hwclock --systohc --utc

Create an initial ramdisk environment:

Configure /etc/mkinitcpio.conf for encryption and LVM by adding encrypt lvm2 (in this order) in the HOOKS section before filesystems so that the kernel will find LVM volumes at boot time. # vi /etc/mkinitcpio.conf -------------------- HOOKS="...encrypt lvm2 filesystems..."

Now generate the kernel image. # cd /boot # mkinitcpio -p linux

Install and configure a bootloader:

# pacman -S grub-bios os-prober # grub-install --recheck /dev/sda

Create a grub configuration file. # grub-mkconfig --output /boot/grub/grub.cfg


Add cryptdevice=/dev/sda2:lvmvg between root=... and ro in the line starts with linux. This needs to be done for "Arch Linux" and "Arch Linux Fallback". # vi /boot/grub/grub.cfg -------------------- linux /boot/vmlinuz-linux root=/dev/mapper/lvmvg-root cryptdevice=/dev/sda2:lvmvg ro quiet

Root password:

Set the root password now. # passwd


Exit from chroot, unmount the partitions, close the device and reboot. # exit # umount -R /mnt/boot # umount -R /mnt # cryptsetup close lvm # reboot

After rebooting, it should ask you for a passphrase like below:


Updating the system:

Sync, refresh, and upgrade the entire new system. # pacman -Syu (or pacman --sync --refresh --sysupgrade)

Pacman will now download a fresh copy of the master package list from the server(s) defined in /etc/pacman.conf and perform all available upgrades.

Note: If you get following errors after executing above statement, it most likely you don't have dhcpcd is not running or your network setting is not correct.

error: failed retrieving file '...' from ... : Could not resolve host: ...

Pacman output is saved in /var/log/pacman.log

Adding a user:

Now add a normal user account for daily tasks # useradd -m -g users -G audio,games,log,lp,optical,power,scanner,storage,video,wheel -s /bin/bash ubyt3m3

Set a password for ubyt3m3 # passwd ubyt3m3

X Window System:

The X Window System (commonly X11, or X) is a networking and display protocol which provides windowing on bitmap displays. It provides the standard toolkit and protocol to build graphical user interfaces (GUIs).

Before installing the X11, try to see what kind of video card you have # lspci | grep -e VGA -e 3D

Then install the base Xorg packages using pacman. # pacman -S xorg-server xorg-xinit xorg-server-utils

During the installation, it'll ask you for the type of libgl. Use below information based on the type of video card you have (returned value from the lspci command above), choose a proper driver.

xf86-video-amdgpu ... mesa-libgl
xf86-video-ati ... mesa-libgl
catalyst ... catalyst-libgl

xf86-video-intel ... mesa-libgl

xf86-video-nouveau ... mesa-libgl
nvidia ... nvidia-libgl
nvidia-340xx ... nvidia-340xx-libgl
nvidia-304xx ... nvidia-304xx-libgl

Install video driver:

My system came with ATI Graphics Card, so install the open source raden driver. # pacman -S xf86-video-ati

Install input driver:

Since this install is for notebook, following package is needed for touchpad. # pacman -S xf86-input-synaptics

Are you installing Arch Linux as VirtualBox Guest?

If you are like me, you'd test the installation of OS or software on a virtual system before actually installing on main systems. I use VirtualBox for that. In order for Arch Linux to run X11 within the VirtualBox guest environment, VirtualBox Guest Additions need to be installed. # pacman -S virtualbox-guest-utils

After executing above command, it'll ask you for guest modules. Choose virtualbox-guest-modules-arch if you used linux kernel when you ran mkinitcpio -p linux during the configuration period. For other modules, use virtualbox-guest-dkms

Loading the VirtualBox kernel modules:

Before getting X11 work on the guest environment, VirtualBox kernel modules must be loaded. To do this automatically, enable the vboxservice service. # systemctl enable vboxservice

Load the modules # modprobe -a vboxguest vboxsf vboxvideo

Testing X:

Install the default environment. # pacman -S xorg-twm xorg-xclock xterm


Install a set of TrueType fonts, as only unscalable bitmap fonts are included by default. DejaVu is a set of high quality. # pacman -S ttf-dejavu

Now, that's a very base system. If you are interested in installing Openbox, you can follow steps in my post, Openbox (w/ Arch Linux).

That's all!

/usr/lib/libjpeg.so: could not read symbols: File in wrong format collect2: error: ld returned 1 exist status

I was in need of installing software on my Slackware64 14.1 on the other day and got a following error message: ... /bin/sh ../libtool --tag=CC --mode=link gcc -Wall -Wstrict-prototypes -Wmissing-prototypes -O2 -fPIC -module -avoid-version -o export_jpg.la -rpath /usr/lib64/transcode export_jpg_la-export_jpg.lo -L/usr/lib -ljpeg -lm -lm -lz -ldl libtool: link: gcc -shared -fPIC -DPIC .libs/export_jpg_la-export_jpg.o -L/usr/lib /usr/lib/libjpeg.so -lm -lz -ldl -O2 -Wl,-soname -Wl,export_jpg.so -o .libs/export_jpg.so /usr/lib/libjpeg.so: could not read symbols: File in wrong format collect2: error: ld returned 1 exit status make[2]: *** [export_jpg.la] Error 1 make[2]: Leaving directory `/tmp/SBo/transcode-1.1.7/export' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/tmp/SBo/transcode-1.1.7' make: *** [all] Error 2

From the error message, I can tell that it has something to do with linker and libraries, perhaps using 32-bit library on my 64-bit Slackware. I checked the LDFLAGS variable in its MakeFile and it was empty.

Ok, is there a way to force the compiler to use 64-bit libraries with SlackBuild scripts?

YES! A variable can be passed to SlackBuild script. To force the SlackBuild script to use 64-bit library, simply add variable with its value before executing a SlackBuild script.

$ LDFLAGS="-L/usr/lib64" ./[SlackBuildScript_name]

VoilĂ . The compilation went through without any more errors!

FreeBSD: Installing VirtualBox — No rule to make target ‘/sys/kern/bus_if.m’ Compile Error

One of the reasons I need VirtualBox on my HP Pavilion laptop is that I need Windows system to access to my work environment. The program only runs on Windows or Mac. I suggested (or rather complained) to make it available for Linux users but to this day my wish hasn't granted.

So let's install VirtualBox from the ports.

The information in this site is the result of my researches in the Internet and of my experiences. It is solely used for my purpose and may not be suitable for others. I will NOT take any responsibility of end result after following these steps (although I will try to help if you send me your questions/problems).

As always, check for updates on ports: # ports fetch # portsnap update

Now follow the instruction in the handbook, 21.3. FreeBSD as a Host. # cd /usr/ports/emulators/virtualbox-ose/ # make install clean ... kmk[2]: *** No rule to make target `/sys/kern/bus_if.m', needed by `/usr/ports/emulators/virtualbox-ose/work/VirtualBox-4.3.10_OSE/out/freebsd.amd64/release/obj/FreeBSDGeneratedKernelHeaders/bus_if.h'. Stop. kmk[2]: Leaving directory `/usr/ports/emulators/virtualbox-ose/work/VirtualBox-4.3.10_OSE' kmk[1]: *** [pass_installs_this] Error 2 kmk[1]: Leaving directory `/usr/ports/emulators/virtualbox-ose/work/VirtualBox-4.3.10_OSE' kmk: *** [pass_installs_order] Error 2 *** Error code 2 Stop in /usr/ports/emulators/virtualbox-ose. *** Error code 1 Stop in /usr/ports/emulators/virtualbox-ose.

Huh? Error? Let's see what went wrong.

kmk[2]: *** No rule to make target `/sys/kern/bus_if.m', needed by...

This line seems to be the root cause. It looks like /sys/kern/bus_if.m is missing? Indeed, there is nothing under /sys. Furthermore, /sys is a link to /usr/src/sys which means I'm missing kernel source files? I then downloaded src.txz from the FreeBSD site. # tar -C / -xvf src.txz

Then compile virtualbox again. This time it went through without any errors! Yahoo!

Now follow the rest of the steps in the handbook. Load the kernel module and update /boot/loader.conf to ensure the module gets loaded at each reboot: # kldload vboxdrv # vi /boot/loader.conf ------------------------------------ vboxdrv_load="YES"

For bridged or host-only networking, add the following to /etc/rc.conf and reboot the computer: # vi /etc/rc.conf ------------------------------------ vboxnet_enable="YES"

To use VirtualBox, all users need to be the member of vboxusers: # pw groupmod vboxusers -m <username>

The default permissions for /dev/vboxnetctl are restrictive and need to be changed for bridged networking: # chown root:vboxusers /dev/vboxnetctl # chmod 0660 /dev/vboxnetctl

Update /etc/devfs.conf to make above change permanent: # vi /etc/devfs.conf ------------------------------------ own vboxnetctl root:vboxusers perm vboxnetctl 0660

Finally, type VirtualBox in a terminal to launch it: $ VirtualBox &

That's all!

FreeBSD 10 with Full Disk Encryption on UFS Filesystem

Since its release on 1/20/2014, I have been trying to install FreeBSD 10 on my HP Pavilion dm3-1130us notebook with ZFS because I wanted to utilize its full disk encryption; however, every time I try, it failed during the boot process with the following messages: gptzfsboot: error 66 lba 48 gptzfsboot: error 66 lba 1 gptzfsboot: No ZFS pools located, can't boot

I googled but couldn't find any solutions even now. If anyone knows how to resolve this, I'm all ears.

The information in this site is the result of my researches in the Internet and of my experiences. It is solely used for my purpose and may not be suitable for others. I will NOT take any responsibility of end result after following these steps (although I will try to help if you send me your questions/problems).

So for now, I'm going to install it with full disk encryption on UFS instead. After many trial and errors, I found steps that worked on my system (thanks to BSD Now). I'll just list commands below just in case the site becomes unavailable in the future (it happens!).


Follow the installation until the partition menu. Choose shell to manually configure the disk encryption before the OS is installed.

To view a list of disk devices, run: # sysctl kern.disks

With a blank disk, run: # gpart create -s gpt ada0

Or destroy existing one: # gpart destroy -F ada0

Create 3 partitions. The first is for the boot record, the second is an unencrypted /boot partition (from which the kernel is loaded) and the third is the large encrypted partition for the rest of the OS and files. # gpart add -t freebsd-boot -s 512k -a 4k ada0 # gpart add -t freebsd-ufs -l bootfs -s 1g -a 1m ada0 # gpart add -t freebsd-ufs -l encrypted -a 1m ada0

Install the bootcode: # gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ada0

Encrypt the partition: # geli init -b -s 4096 ada0p3 Enter passphrase: Reenter passphrase:

Attach the device: # geli attach ada0p3 Enter passphrase: cryptosoft0: on motherboard GEOM_ELI: Device ada0p3.eli created GEOM_ELI: Encryption: AES-XTS 128 GEOM_ELI: Crypto: software

Format the partitions: # newfs -U /dev/ada0p2 # newfs -U /dev/ada0p3.eli

Mount the partitions: # mount /dev/ada0p3.eli /mnt # mkdir /mnt/unenc # mount /dev/ada0p2 /mnt/unenc # mkdir /mnt/unenc/boot # ln -s unenc/boot /mnt/boot

Create the fstab file: # vi /tmp/bsdinstall_etc/fstab ---------------------------------------------------- # Device Mountpoint FStype Options Dump Pass# /dev/ada0p2 /unenc ufs rw,noatime 1 1 /dev/ada0p3.eli / ufs rw,noatime 2 2

Automatically load the kernel modules that are required for booting from an encrypted volume: # vi /tmp/bsdinstall_boot/loader.conf ---------------------------------------------------- geom_eli_load="YES" vfs.root.mountfrom="ufs:ada0p3.eli"

Exit out and follow the rest of installation. After rebooting, it should prompt for passphrase.

However, on my system there was a bit of gotcha after the reboot: FreeBSD10_encryption

As you might see in above image, some kernel messages followed right after the passphrase prompt. I did not realize this for a while and made me think that the encryption failed (and it took me a while to figure out...). To confirm the encryption is working, press Enter. The passphrase prompt shows up again: GEOM_ELI: Wrong key for ada0p3. Tries left: 2. Enter passphrase for ada0p3:

That's all!
