I just received my GnuBee Personal Cloud 2 in the post. It's a device newly manufactured specifically to run completely free software, making in completely unique. The device is designed for network accessible storage, providing slots for six 3.5" hard drives.
As a brand new product, the documentation for getting started is nearly non-existant though, so here's my journey so far.
I was surprised to see that the holes for the circuit board mounting brackets didn't all line up. It turns out that the centre brackets are oriented differently to the end brackets. Look carefully at the photo below.
The GBPC comes with the LibreCMC operating system installed in the on-board flash memory.
Based on the Background information for GnuBee PC1, I plugged a network cable in to the black socket and plugged the other end in to my computer. I then tured on the GBPC using the silver switch (red button on GBPC1). No SDCard was installed at this point.
Once it had started up, the computer connected to the GBPC's network. Visiting
http://192.168.10.1/ in a web browser showed the LibreCMC login screen. Although
it's not made clear, you can initially log in as user "root" by leaving the
password blank. You can also connect with SSH with no password by running
-o StrictHostKeyChecking firstname.lastname@example.org with no password. I needed the
StrictHostKeyChecking as I also have a GBPC1 that uses the same IP address.
Proceeding to the System/Administration section allows entry of a root password. I set up key-based SSH access at the same time. Leave "Interface" as "unspecified", uncheck password authentication and enter your SSH public key fingerprint (from .ssh/id_rsa.pub). Select "save and apply" at the bottom of the page. I was then able to log out and log back in with my new password, and connect with SSH to email@example.com.
Unfortunately I notied that after switching the device off and back on again, the password and SSH changes were reset. I'm not sure why.
The GnuBee devices are not well documented at the moment, but at present the best information can be found at:
Installing hard drives
I installed a hard drive in slot 1 and after resetting the GBPC with the black
reset button, noted that the new drive was listed under the System/Mount Points
section as filesystem "crytpo_LUKS". The second drive was an unencrypted "ext4"
drive. That didn't show up under "Mount Points" automatically and didn't seem to
mount when I selected "Add", chose the drive from the list and defined a custom
/backup. There was no problem mounting this drive from the SSH
command line though.
At this point I still have a lot of questions, and not enough time to investigate them all. If you know the answers, please get in touch.
Do I need to install a different operating system to do something useful with the device? I was a little suprised to find that the GBPC doesn't do anything much out of the box. Not that this in any way limits the device's potential, but it's nice not to have to do everything yourself. It seems that all drive mounting must be done manually, that there's no file sharing services or even rsync installed by default.
How do you install software on LibreCMC? I tried the System/Software section of the web interface, but installing or searching for packages fails with an error connecting to the package repositories.
How do you boot from the SDCard included in my "deluxe pack"? The card appears to have Debian installed, but after insterting the SDCard and resetting, the device still seem to boot to LibreCMC. Noting that the SDCard is auto-mounted if inserted while LibreCMC is running.
What do the different network ports do? Black is a LAN port. Blue seems to be the WAN port as the device can ping the outside world once plugged in. The yellow port doesn't seem to do anything.
Can drives be made to auto-mount? I noticed that plugging in a USB drive are mounted automatically under
How do you connect with the USB-to-UART cable? I tried plugging it in, connecting with
picocom /dev/ttyUSB0 9600and resetting the GBPC, but only see garbage on the screen. Clearly I need different connection settings.
Why don't password changes stick? Cleary the device is accepting some changes, because if I
mkdir /mnt/backup, the directory is still there after a power off and on.
Can it be configured to be a DHCP client, rather than a DCHP server?
Update 5 Feb 2018
I learnt that USB-to-UART works via minicom, eg.
sudo minicom -b 57600 -D
/dev/ttyUSB0. See the GnuBee
documentation. I presume that
minicom must use different defaults to picocom.
It appears that a (firmware update)[https://groups.google.com/forum/#!topic/gnubee/vbKwd7r-8_8] is required to allow booting from the provided SDCard.
The network interface for LibreCMC can be changed from "static" to "DHCP client".
I'm having trouble mounting some encrypted drives. It appears that missing kernel support for "aes-xts-plain64" may be the cause.
Update 7 Feb 2018
Plugged two RAID1 drives into the GBPC2 and it correctly recognised the three
RAID partitions and allocated them to
opkg update command, as well as the web interface fail to update the
package list with:

In contrast, my LibreCMC-based router from ThinkPenguin updates and installs packages with no problems, so clearly something just isn't configured correctly.
Password changes do appear to be saved, and persist across reboots and powering off. It appears though that the small black button does a "factory reset", which resets the LibreCMC login credentials.
The hard drive idling plugin available through the web interface works well.
Slot #1 on the GBPC2 is blocked by the two 12V plastic clips. This is a minor design fault, but you can simply bend the four plastic tabs firmly down to fix the problem.
