WD MyCloud Mirror Gen2 (BWVZ, GrandTeton)

Hi Carl,

the forum mangled the patch, get it from my server: patch

Martin

Great work ! I'll test this soon and deleat the reboot / powerdown from the mcm-daemon

Just a remarks on naming: I'm wondering if ex2u is the right name for "this" device. As the mcm2 and ex2u is basicly the same device so i thought wd-385 might be better. But I'm open with naming, but think consist naming is a good idea.

Again, great work!

Reboot & Poweroff is working :-), but halt did not turn off the fan :-/

-------------------------------------------------------------------------
GitHub https://github.com/cschil

Hi Carl,

yes, there is no handler for halt implemented. It doesn't turn of the power or anything. But I guess that's how it's supposed to be. The fan can't get turned of on halt as the cpu and the disks would be left running anyways.

So to get rid of halt, you can make it an alias for powerdown.

I change the mcm-daemon in my github:
- removed shutdown
- tweaked the fan a bit

So the mcm-daemon works with the your patched kernel.

hm,.. but disk's and cpu should be powered down on "halt", and my old nas rn102 did so, but I can live with this :-)

Hi Carl,

thank you, I recompiled the mcm-daemon from your repository and it works for me too.

Have you made any progress on the init-stuff (raid, crypto, ssh)?

I updated my github, but git and empty folders are not the best friends :-|, but the uInitrd is also uploaded

+ raid works(mdadm + btrfs).
+ If it can't boot it drops to a ssh shell.

crypto I'm working on.

Futher problems: ssh/scp is some how not working; no ssl support form busybox

-------------------------------------------------------------------------
GitHub https://github.com/cschil

So small update on initrd:
+scp now working
+crypto / LUKS working and has to be unlocked by key via dropbear
+LVM ( but not tested)

TODO:
- dropbear has wrong PATH

Hi Carl,

thanks, I'm testing it at the moment.
cryptsetup is working and so is lvm.

What is missing is mke2fs in the "real" version, which can also make ext4-filesystems. Also is there a mechanism to search for crypto keyfiles? Maybe to put a keyfile onto the flash, where the mac-address file is would be an idea.

ssh login also worked for me. Putting an ssh authorized_keys file in the ubi partition and disable the password-free root login might also be nice.

What do you think?

Martin

god to hear :-)

OOps, I see its allready in (twice) as mkfs.ext3 / mkfs.ext4, but I'll change that.

No, but I can integrate one, but how is the "best"

Sure this is possible, but in my opinion it provides only less security, as the key could be easy read out form the device.
Maybe a Self-Decrypting is then easy and provides the same kind of security.
A better way could be to store the key on a usbdrive as this can be physical removed.

Okay, I think i fixed the PATH problem as well :-)

Okay, what do you have in mind?

To enhance security,...hm, I don't see here a way in both.
You have at first bring the key on the nand, either its "public on the web" or if you generate it on first boot it could be read or copied by booting a initrd without password check :-/

So comments :-)

I didn't search for that name, but that's fine too.

Well, that depends on why you encrypt your discs. I encrypt the discs on servers or at home mostly to be able to dump them without further thought when they are broken or too small.

Yes, this is also a good idea. Maybe just search in some locations for a key and use it, when it is found.
That way the user could decide how he want's to use it.

I suggest the following steps:

1. check nand for a file named "crypttab" and use it
2. use findfs to look for a filesystem named "rootfsinfo" and use that

The PATH in ssh is missing /sbin and maybe /usr/sbin.

Also waiting for /dev/mapper/cryptroot is not optimal when running with lvm. If I open the luks device with "cryptsetup -T 5 luksOpen /dev/md0 cryptroot", the kernel panics as the init script finds the device, but lvm is not yet up. To get it working with lvm I have to do the following steps via ssh:

~ # /sbin/cryptsetup luksOpen /dev/md0 lvm
Enter passphrase for /dev/md0:
~ # /sbin/lvm vgscan --mknodes
  Reading all physical volumes.  This may take a while...
  Found volume group "eboc" using metadata type lvm2
~ # /sbin/lvm vgchange -a y
  3 logical volume(s) in volume group "eboc" now active
~ # touch /dev/mapper/cryptroot

Nevertheless, stupid systemd fails to boot the system. I have 3 logical volumes in the volume group:

• 30GB rootfs labeled "rootfs"
• 2GB swap labeled "swap"
• 200GB storage to be mounted on /srv labeled "storage"

Well, I'd keep it simple. Maybe just check if there is a authorized_keys file in
/mnt/config and if it's there and readable, then start dropbear with it and disable
password authentication and password-less login. If it's not there, then just keep
the behaviour we have now.

Anyways, thanks a lot for the big progress with the Ramdisk.

Hi Carl,

me again.

Actually after thinking about it, the best idea might be to check for a directory named "dropbear" in the NAND under /mnt/config and use that as config directory. That way one could also copy the ssh-host keys there ti have the same fingerprint as the booted debian system.

Well, just a thought.

bye
Martin

hey Martin,
I add crypt-lvm support, so it should boot now your system, and as written above ssh PATH is now right.

For writing things in "config" and provide "key" options might be good idea. I'll think about it.
The most beautiful way, would be a small webserver for key insert and configuration, but this is to much effort for this project.
So your right, keep it simple :-)


For your Debian / systemd problem I don't know whats going on there.

As I'm not using (and never realy had used) LVM, I'm not realy into the problems there.
I'll look into it tomorrow or you can just make a commit :-)

So I changed over the holidays a few things in the initrd:
check my github

Dropbear:
+ changed port to 2222
+ readded fingerprint
+ pubkey unlock possible: stored on nand

Crypto:
add key unlock from nand / usb:
+nand /dev/mtd5: /initrd/key.luks
+usb LABEL=key: /key.luks

Initrd
+ changing and save/store root-password on nand
+ resuming boot-script (buggy /switch_root not working)

What I like to integrate is a bootinterrupt by pressing the resetkey, but I don't know the mmp for the reset gpiopin :-/

Fancontrol is not my friend for now to fast or to slow.
So i think more steps would be better.
fox-exe (the russian guy) has a "fan-gpio-script" but I don't get it to work. there is as well a python-scrpit, but I don't like python for the extra libs.

@MM As you are a better "coder" than I am, have you maybe looked at qcontrol for qnap-nas; thougt this cloud be a good base for a "control" script.

-------------------------------------------------------------------------
GitHub https://github.com/cschil

Updated the initrd in my github:
I add resetbutton support: with pressing resetbutton you can enter rescue-shell now without uart.

Somehow shutdown is not working any more; the device is rebooting every time :-/ and have no idea why.

To keep it simple I reworked the fancontrol script from Lorenzo Martignoni with more fan-states.
I will upload the sources and an patched rootfs when its tested.

-------------------------------------------------------------------------
GitHub https://github.com/cschil

Hi Carl,

I'm back from holidays. Thanks for your improvements. They work for me with minor changes.
Here some remarks:

- you check for /sbin/init as a symlink which didn't work for me as /sbin/init is an executable
- when the passphrase in /mnt/config/initrd/luks.key is wrong (trailing newline) no shell is started to fix it
- the console is lost after the first init and no further boot messages are shown

For me shutdown still works, so I guess it's an kernel issue. I have seen the instant reboots in case of powerdown when I was playing with wakeonlan. It seems the micro controller sometimes wakes the device on ethernet activity. Try to powerdown the device with the ethernet unplugged and let me know if it still reboots.

I guess I will have a shot an implementing a PID-controller for the fan in the mcm-daemon, but this will take a bit of time.

I also found some basic info on how to read the fan speed from the MCU but don't have the speed table yet to convert the reading into the correct rpm value.

Martin

yep, was my idea as well, as I played with Wol.

Sry, but I really don't like the mcm-daemon as it is.
("iniparser" and config over telnet")

So I switched to python:
(I know C(++) might be better for all lib in the file but my C skills are limited :-/)
I uploaded (the unready, but) good working fancontrol to github.
No idea what a PID-controller is, but the "new" controlscript is working with much lower temp and lower noise / fan speeds.

Found that out as well and planed to integrate this.

Besides Wol and RCT-wake, I'd really like to see the powerled integrated in a kernel module to use led-triggers on this.

After switching to the "real" init on the rootfs, no output from the boot scripts
is sent. I see only kernel messages and after a while the serial login prompt.

Well, I won't implement this since it's awful. Either everything the mcm-daemon/control script
does must be implemented in kernel, or one would have to somehow decide how to control
access to the MCU as two parties would be accessing it. I think the shutdown/reboot thing is
a good compromise as userspace should be dead by the time I access the MCU from the kernel.
Even if userspace would not be dead, it is dead after the kernel issues the shutdown/reboot commands.

That's why I don't consider the the mcm-daemon too bad. It has a socket interface (telnet) and can be
easily by shell scripts and from udev. So you can use the power LED that way. Maybe changing the
network socket to a UNIX domain socket would be a good idea.

I'm not missing anything, and will post a bootlog later.

I somehow forgot this. I just like how simple led's are controled through a virtual /sys/class/ device.

I'm totally with you it is not too bad. But besides the "network socket" the iniparser is a downside of it me a problem as well, because the iniparser is not in the repo's of the big dists debian/ubuntu/arch. And this makes installation more difficult.
So I'm more into writing things total new, as for now only fan-control and powerled is really used and working.
Thats why I thought the qcontrol script should be a good base for rewriting

But I still like the idea of providing virtual devices by the kernel, so "standard" userspace programs could be used to control everything. ( I see this is the most work)
e.g.: fan by fan-control; led by kernel trigger, rtcwake would work

This might be of interest to you guys with this box. This stock u-boot might be the same one as the NAS326 and will mess up the DTB when booting with separate DTB.

Hi Carl,

i made the first changes to the mcm-daemon and added the ability to show the fanrpms.

echo "GetFanRpm" | nc -q1 localhost 57367

github

After reinstalling debian from scratch with my kernel and the debian install ramdisk I also get the boot messages. I guess something broke, when I replaced systemd with sysv-init. Now it works.

What doesn't work for me with your initrd is getting a shell by pressing a key on the serial console, but pressing the reset button works for me.

bye
Martin

I have added debian packaging to the repo. It will also build the iniparser library and link the mcm-daemon statically to it.

You can build a debian package for easy installation with:

dpkg-buildpackage -uc -us -b -t arm-linux-gnueabihf

Hm,.. strange, did you pressed only "enter" or some "abcd..." key; as "enter" did not work for me either.
maybe I should rework this code.

Okay, I try to implement "10-step" fan-control into the mcm-daemon from the python fan-control

Update:
I modified the fan-control lines and will test this tomorrow. If its working, its change the speed in small steps and I'll commit this to your git :-)


cheers Carl

Hi Carl,

great, let's see what you find with the key press problem. I tried different keys and none that I tried in the 5 seconds worked. But that is not really important.

I'm looking into implementing a PID-controller in the mcm-daemon but will have to rework the logic of the mcm-daemon before this makes sense. I will do this mainly out of curiosity as I haven't tried something like that before, but I guess I'll learn a lot by trying it. Especially if you look at the tuning section on the wikipedia page, this sounds like an interesting playground. I will make the Kp, Ki and Kd constants available in the config file, so no recompilation will be needed for tuning. I also want to include the temperature of the harddisks into it, which can be acquired with "smartctl -A /dev/sd[ab]" and which does the original daemon in the WD firmware.

I acquired two Toshiba 2.5" 3TB harddisks (MQ03ABB300) and adapters for 3.5" to keep the system quiet and cool. Currently it works at 38C system temperature and 31C disk temperature when idle without the running fan and a power consumtion of 5.4W including one usb2-hub and one DVB-T usb receiver, which is really great. When I give it some work the power consumption increases to a maximum of 14W and the fan starts running. I have set TempLow to 42C in the mcm-daemon.ini file.

I guess I will also convert the interface to an unix domain socket and provide a client application for it if netcat won't do the job.

The EX2 ultra also has a red LED behind the power LED, which I also would like to control, but I haven't figured out the serial commands for that yet.

bye
Martin

Hey Martin,

The PID-controller sounds really interresting and would be a "nice to have" feature.
( besides I think it is not needed as rapid tempreture increase and decrease does not happen)
I merge your mcm-daemon on github and reworked the fan-control, in my opinion it is working better, with lower noise. Maybe you can have a look at these lines and maybe it helps with the pid.

To include the harddisk might be a good idea, but then cpu-temp has to be integrated as well. With ~45 °C at the MCU the CPU is at ~60-75 °C.
With 2.5" disk you won't have a problem with noise and temperture. To have a "worst" case, I'm using for test's some old 3.5" WD 7.2k enterpise disks.

For a client application, do you think of a sepreate program or somkinde like

# mcm-daemon start
# mcm-daemon get-fan
..

For the power led, I even saw a short yellow light, right after start up. :-).

Besides there is an "mcu-firmware upload" in the original firmware, perhaps there is a way to dump it some how?! (to be honest I have no idea how and if these data are some kind of readable)

-------------------------------------------------------------------------
GitHub https://github.com/cschil

Hi Carl,

I updated the mcm-daemon to full control of the Power-LED and to include the harddisk temperatures into the fancontrol.

The Power-LED can blink and fade in blue, and it can blink or shine in organge, red and blue. I tested it with the original Firmware. Combinations of the above are not possible as only one register is used for control via the mcu.

I didn't go for a PID-controller, as it wasn't really suitable for the task when looking closely at it, as there is no "destination temperature" to aim for. Instead I implemented something similar as you did in your repo.

If you test it, let me know how it performs. I will start testing with some old 3.5" drives tomorrow I think. Upto now I only used my 2.5" disks, which are quite cool anyways.

bye
Martin

Hey martin,

really nice work ! & Big Thanks !

Few things:
- 80 for min speed is quite high and why hardcode this value:
What about check on first start the "fanstart" value and add for safety 5 or so

for smaller thinks I'll just do commits
