UFS UFS created on AMD64 not found by ARM?

Hi!

This is my first post so tell me off if I'm doing it wrong. I'm a FreeBSD newbie but eager to learn.

I have a Raspberry-Pi which I have working fine with the FreeBSD-10.1-RELEASE-arm-armv6-RPI-B.img from the FTP. My problem is attaching storage in the form of an external USB drive. I can't get a properly formatted drive to show up.

Following 18.2. Adding Disks in the handbook I tried partitioning and formatting the drive directly on the Pi, I get:
Code:
root@raspberry-pi:/ # gpart create -s GPT da0
gpart: scheme 'GPT': Invalid argument
I can use MBR as my partitioning scheme but then I still can't create a freebsd-ufs partition.

Code:
root@raspberry-pi:/ # gpart create -s mbr da0
da0 created
root@raspberry-pi:/ # gpart add -t freebsd-ufs da0
gpart: Invalid argument
So perhaps gpart(8) on ARM doesn't work as I expect, fine. I create a FreeBSD VM in Virtualbox on my Mac, pass through the USB disk to it and successfully follow the steps in 18.2 to newfs -U /dev/da0p1 doing ls /dev in the VM showed da0p1 had been created. Great, I shutdown the VM and pop the USB drive into the Pi and reboot. But the Pi does not show the UFS partition I just created, it only lists /dev/da0, there is no /dev/da0p1, even though it showed up fine in the VM. Is UFS different between ARM and x86 versions of FreeBSD?

I have also tried formatting the drive as FAT32 on my Mac and then moving it to the Pi but that didn't seem to support proper permissions so I would much rather use UFS or another properly supported file system.

Any tips on how I can move forward on getting a USB hard drive working on FreeBSD ARM on my raspberry pi? Can I get gpart(8) working as expected on ARM? Or should I format the drive in some other way on another machine than the pi?

I'm grateful for any help on this, I'd really like to move to FreeBSD on all my boxes and having to put Raspbian on this one would be a bit of a failure :(

Here is my dmesg output. The disk I want is umass0/da0.

Your ARM Kernel probably lacks support for the GPT schema. IIRC it can be loaded as kernel module.

I found a GPT module in /boot/kernel/ called geom_part_gpt.ko which I loaded and then it could partition and format the drive!

Code:
root@raspberry-pi:/usr/home/efx # kldstat
Id Refs Address    Size     Name
1    1 0xc0100000 6d81c4   kernel
root@raspberry-pi:/usr/home/efx # kldload geom_part_gpt
root@raspberry-pi:/usr/home/efx # kldstat
Id Refs Address    Size     Name
1    4 0xc0100000 6d81c4   kernel
2    1 0xc1d8b000 d000     geom_part_gpt.ko
root@raspberry-pi:/usr/home/efx # gpart create -s GPT da0
da0 created
root@raspberry-pi:/usr/home/efx # gpart add -t freebsd-ufs da0
da0p1 added
Thank you so much! I got it working and I learned something.

Hi!
I can use MBR as my partitioning scheme but then I still can't create a freebsd-ufs partition.

Code:
root@raspberry-pi:/ # gpart create -s mbr da0
da0 created
root@raspberry-pi:/ # gpart add -t freebsd-ufs da0
gpart: Invalid argument
I realise you fixed the problem with using GPT, but the reason why the above didn't work is because you created an MBR partition table on the device, but didn't create an MBR partition to contain a nested BSD partition table and partition. It should have been as follows:

Code:
# gpart create -s mbr da0
da0 created
# gpart add -t freebsd da0
da0s1 added

# gpart create -s bsd da0s1
da0s1 created
# gpart add -t freebsd-ufs da0s1
da0s1a added
For the MBR scheme, you needed a partition (or slice) of type 'freebsd'. Then inside that slice you create your BSD partition of type 'freebsd-ufs'.
