Problem booting NSA325v2 on HDD

Dear bodhi,

first of all a big thank you for your great work!

I used your 2016.05 U-Boot on my NSA325v2 and everything went fine so far.
I am also using your Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2 on my USB-Stick which is also working well.

As this new U-Boot should be able to boot ext4 rootfs i wanted to switch to an ext4 rootfs on the left sata disk which becomes sda when i remove the usbstick.

Because the harddisk is 3TB i made a clean GPT partition table and created partition 1 with 50GB and formatted it with ext4 and labeled it rootfs.
Then i followed your instructions for installing the rootfs on the stick by using the partition i just created on the disk.
After removing the stick it starts to boot but then gives kernel panic.

Here is the end of the output before it stops

Unfortunately i am not able to get all output as i am using my raspi with "sudo screen /dev/ttyAMA0 115200" to get to the console and the first parts are no longer available.

Something i must be doing wrong but couldnt find it yet.

Here is my printenv output:

saschadd,

Don't use screen. picocom is among the best tools for serial console. On rPi you can install picocom, and you will be able to capture the entire serial boot log.

apt-get install picocom

This error is becasue the rootfs could not be mounted. And that usually is because one of the following:

1. kernel bootargs was not set properly. Either the serial boot log, or at the minumum dmesg output, must be captured and posted here so I can see what it looks like.

2. A missing step somewhere during the creation of the rootfs. The rootfs instruction must be followed verbatim. If you had to replace a step with something equivalence, then that step might have been wrong.

3. Especially, since you are booting with the new u-boot, step 4 in the rootfs creation is not applicable. You can look at the /boot on the rootfs to see if you have mistakenly appended the DTB to uImage.

After you have checked 3 items above and still can not boot, then please post the entire serial bootlog here.

bodhi,

thank you very much for pointing me into the right direction and for the tip with picocom which is far better.
Well its my first time working on the serial console and so i took the first tutorial which mentioned screen. ;)

I rechecked everything and found some mistakes i made.
So i did the uboot update again step by step and then i tried the ext4 rootfs again and it is booting up as expected.
Will it be possible to boot up an btrfs rootfs in the future?

Only thing that is not working yet completely is systemd as the command systemctl gives me following error

Failed to get D-Bus connection: Unknown error -1

I already tried to find some hints by searching the forum and the internet but havent found some yet.
Maybe you know what is causing this error?

Cool!

You can boot with btrfs rootfs already! but this requires you to have /boot folder in a separate partition, and it must be the first partition. So the disk drive must be formatted with 2 partitions, boot partition (1st) is ext3/ext4, rootfs partitiion (2nd) is btrfs. U-boot can only load the kernel from fat/ext2/3/4 file system.

Did you set up the bootarg to run with systemd?

Quote

Note2:

To boot with systemd, add this parameter to your u-boot env bootargs. If you are booting with my latest u-boot images then use the uEnv.txt capability to do this. See the instruction about uEnvt.txt in that thread.
init=/bin/systemd
For example,
fw_setenv usb_set_bootargs 'setenv bootargs console=$console root=$usb_root rootdelay=$usb_rootdelay rootfstype=$usb_rootfstype $mtdparts init=/bin/systemd'

If that's still not possible to run systemd, you might want to install it again:
apt-get install systemd

If the systemd problem persists, do apt-get update and apt-get upgrade.

LOL about myself now :D

I made completely nonense regarding the systemd.
I just made an file uEnv.txt in /boot and entered just init=/bin/systemd into it.
This couldnt have worked as expected.

I checked my env again and found this line

set_bootargs=setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 $mtdparts $custom_params

and added the init=/bin/systemd to it be executing

fw_setenv set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 $mtdparts $custom_params init=/bin/systemd'

Now it is working as it should. Sorry for this stoopid mistake. ;)


Regarding the btrfs boot:
Is it sufficient to
- make partition 1 with ext4 and label boot
- moving folder boot to that new partition
- make partition 2 with btrfs and label rootfs (will this work with btrfs raid1 made of sdb1 and sdc2?)
- moving anything else to that partition

Do i have to modify anything in /boot so that the new rootfs gets found?
Sorry for so many questions but i am very new to this modifying of the "standard install".

sascha

I tried to be not to shy and try it on my own with trial and error. ;)

Btrfs gets loaded but then it gets stuck

Btrfs loaded

done.

done.

After some more failure messages i get thrown to BusyBox.
So far my own try was not as successful as i wanted it to be.

saschadd,

Best that you post the entire serial boot log, until the initramfs prompt where the rootfs could not be mounted.

saschadd,

With systemd, there are many bugs in earlier version. So I would

1. upgrade the kernel to linux-4.9.0-kirkwood-tld-1-bodhi.tar.bz2

2. And then do apt-get update, apt-get upgrade.

3. Add btrfs to list of modules to /etc/initramfs-tools/modules. And regenerate initramfs and uInitrd.

One minor problem in bootargs that should be fixed:

You are right.
Well this is the original rootfs version 4.4.0-kirkwood-tld-1 - released 20 Feb 2016 just unpacked to the btrfs raid 1 rootfs and moved /boot folder to partition one labeled boot.

To update the kernel i need the system already up and running or am i wrong?

This has to be done on the running system as well?

Thanks, fixed it in mtdparts.

saschadd,

You should boot up the Ext3 rootfs, upgrade the kernel, apt-get upgrade. And then copy the Ext3 rootfs to an empty btrfs partition.

Normally, you could chroot into a rootfs that is not running and then upgrade kernel and packages. But these 2 are newly created rootfs, so it is really simpler to upgrade the kernel on a live system than chroot into the btrfs partition.

Similar answer as above. Should do this right after upgrading kernel, since the uInitrd needs to be regenerated. So do this is a live system is simpler.

All that said, if you have already installed a lot of stuff in the brtfs rootfs, then do everything by chroot into it will save time.

I already had the idea about doing this on on the already running live system on the stick and then moving to the sata drive.
But i had the idea while on the road so i am just yet able to try.
Do i have to copy it with a special command or just copy everything from sda1 to sdb1 for example.

As i am brand new to this initramfs and unitrd rebuilding i dont know where to get that btrfs module.
Is it already somewhere on the rootfs or do i have to download it somewhere?

Use a different Linux box. Assuming your USB is mounted at /media/sda1, and HDD is mounted at /media/sdb1. Become root, and copy

su
cd /media/sdb1
time cp -aR /media/sda1/* .

Here is an example for addding the netconsole module and regenerate initramfs. Put the module name btrfs in file /etc/initramfs-tools/modules.

http://forum.doozan.com/read.php?2,9522,9522#msg-9522

Note: this adding module name might be redundant, but with a possibly buggy systemd, it might serve as a workaround the bugs.

bodhi,

i was already working on this over the day and got the btrfs module loaded etc.

But i think the kernel module is not able to load an btrfs raid1 rootfs as i get the following error when booting it.

Btrfs loaded, crc32c=crc32c-generic
Begin: Will now check root file system ... fsck from util-linux 2.25.2

mount: mounting /dev/sda2 on /root failed: Invalid argument
done.

Just tried to have just a single btrfs partition without raid and this is starting, even if systemd gives me some failures

...
[FAILED] Failed to start Load/Save Random Seed.
...
[FAILED] Failed to start Update UTMP about System Boot/Shutdown.
[DEPEND] Dependency failed for Update UTMP about System Runlevel Changes.

Maybe it is a problem of the raid1 or of my different approach to copy the rootfs while running with

tar -c --one-file-system -f - . | (cd /media/sdb2/; tar -xvf -)

But as it is quite late in Germany and i am sitting already to long in front of the monitor today, i will check this tomorrow.
So far i am happy with the results even if it is not already everything set.

I wrote down what i did, which i could post as a howto for other people who want to achieve the same. ;)

After some more reading and testing i think it is not that the boot of an btrfs raid is impossible but you have to boot it with uuid

Now i tried to set the bootargs for sata boot in uEnv.txt but it is not working as intended.
Thats my uEnv.txt which gets loaded but does nothing.

sata_root=2f613613-85b4-46cf-bbbe-90a1748f7753
sata_rootstype=btrfs
sata_rootflags=defaults,compress,subvol=@
set_bootargs_sata=setenv bootargs console=$console root=$sata_root rootdelay=$rootdelay rootfstype=$sata_rootfstype rootflags=$sata_rootflags $mtdparts

Do i use wrong variables? Is there a list of available uboot variables somewhere?

saschadd,

> Do i use wrong variables? Is there a list of avail
> able uboot variables somewhere?

Either root LABEL or UUID should work.

root=LABEL=rootfs

require initramfs, i.e. uInitrd

root=UUID=2f613613-85b4-46cf-bbbe-90a1748f7753

does not require initramfs, but you are limited to this UUID. This is how Arch boot without initrd (therefore the LABEL option is not available to Arch).

And judging from your boot log, the btrfs file system was regconized by the kernel, so sata_rootstype=btrfs is redundant. But it does not hurt to specify that bootarg explicitly.

Try UUID bootarg and get it working first, if that is necessary. And then play with LABEL, because rootfs LABEL is the best way to boot a rootfs.

Hmm, confirmed that the reasion for the failures

[FAILED] Failed to start Remount Root and Kernel File Systems.
...
[FAILED] Failed to start Load/Save Random Seed.
...
[FAILED] Failed to start Update UTMP about System Boot/Shutdown.
[DEPEND] Dependency failed for Update UTMP about System Runlevel Changes.

was not my different approach of copying.
They persist even after copying with your command

time cp -aR /media/sda1/* .

Trying to boot with non raid1 btrfs and then converting it to raid1 with

mount /dev/sdb1 /mnt
btrfs device add /dev/sdc1 /mnt
btrfs balance start -dconvert=raid1 -mconvert=raid1 /mnt

does also not do the trick.

So i assume i am trying to do something which isnt possible. ;)

Okay, i need to make a btrfs device scan before the rootfs gets mounted as stated in the official btrfs FAQs.

With multiple devices, btrfs normally needs an initramfs to perform a device scan. It may be necessary to modprobe (and then rmmod) scsi-wait-scan to work around a race condition.
....

btrfs device scan

This should be in many distributions' startup scripts (and initrd images, if your root filesystem is btrfs), but you may have to add it yourself.

I have to add somewhere in an script something like the following

mount_root() {
    echo "scanning for btrfs filesystems.... will take about 5-10 seconds"
#
#  earlier versions of btrfs required devices on scan.  As of around 0.19.11 or so this now is a syntax error
#
#    /sbin/btrfs device scan /dev/sda /dev/sdb
    /sbin/btrfs device scan
    echo "mounting /mnt/root"
    mount /mnt/root
}

But how do i modify the initramfs to do this?

I am feeling like following the white rabbit... it goes deeper and deeper....

saschadd,

1. Have you added the module to initramfs-tools/modules ? this is the way to tell the kernel to beware of btrfs earlier.

2. If in doubt, switch back to sysvinit and work this out. That eliminates an unknown variable. IIRC, systemd had some problem with mounting btrfs in the past.

Yes, module is added and loaded at boot.

Unfortunately this doesnt change things.
After removing systemd by doing

fw_setenv set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 $mtdparts $custom_params

the following is the output of console boot

After reading and trying so much today i am blind to details but maybe you see a failure there.

As already said i am going so far down the rabbit hole... but somehow i can't let it go... ;)

So i retried installing it only on one partition without raid1 first.
I figured out that the btrfs rootfs will be mounted ro if you dont correct the fstab.
Maybe i missunderstood something but i thought fstab is no longer necessary with newest uboot.
Anyhow got this working and then systemd is running without problems.

After having it running on btrfs without raid1 i made the rootfs a raid1 by adding a device and balancing it.
This worked without problems.

After that i updated the boot files with

update-initramfs -u -k all

this command gave me the following error:

update-initramfs: Generating /boot/initrd.img-4.9.0-kirkwood-tld-1
Warning: /sbin/fsck.btrfs doesn't exist, can't install to initramfs, ignoring.

This failure can be ignored if i can trust the description on that site http://www.linuxfromscratch.org/blfs/view/svn/postlfs/btrfs-progs.html

fsck.btrfs does nothing, but is present for consistency with fstab.

finally i regenerated uImage and uInitrd

cd /boot

mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-4.9.0-kirkwood-tld-1 -d vmlinuz-4.9.0-kirkwood-tld-1 uImage
 
mkimage -A arm -O linux -T ramdisk -C gzip -a 0x00000000 -e 0x00000000 -n initramfs-4.9.0-kirkwood-tld-1 -d initrd.img-4.9.0-kirkwood-tld-1 uInitrd

After that i rebooted and.... tata... busybox :( So nothing changed.

But i just found the information that it would work with an /dev/mapper/rootfs entry in fstab as btrfs is clever enough to populate the array then. https://blog.samcater.com/fix-for-btrfs-open_ctree-failed-when-running-root-fs-on-raid-1-or-raid10-arch-linux/

Even if this is vor arch-linux, could this be done on debian as well?
As i havent found any useful tips about devmapper usage or configuration in debian it might be very difficult to do but maybe you already did something like that and its gonna be easy. ;)

This is correct. fsck needs to find the binary to check the file system. But no check is needed.

Try look for tips about using mdm in Debian. There might be some useful info in that angle.

I don't use btrfs (but I know it is possible) so I can't fill in the details. You are our btrfs pioneer here :)

bodhi,

it is possible!!!
I got it working!!!
I noted down what i did to get it up and running and will do a howto for others.

Thanks for your help and sugesstions even if the problem was selfmade by me.
I tried to get it up and running with the newest btrfs-tools installed via make install.
By doing this there is the file local-premount/btrfs missing and therefore the kernel cant assemble the array.

I will let you know when the howto is ready so you can add a link to the wiki.

That's what I recalled was similar to one of systemd bugs in the past about assembling the array!

Hello saschadd and bodhi,

I'm having the exact same problem on my raspberry: the raid1 is not assembled at boot. Can you point me to the solution of this issue?

Kind regards
Avio

Avio,

I've asked saschadd to post the solution.

Hi Avio and bodhi,

thanks for the "little reminder". ; )
I was about to forget to post the howto because i am stuck at my next step of setting up a backup box with bareos.
Unfortunately bareos seems not to be usable with actual openssl versions as i get failures

crypto_openssl.c:131:1: error: expected constructor, destructor, or type conversion before ‘IMPLEMENT_STACK_OF’ IMPLEMENT_STACK_OF(RecipientInfo)

followed by many more until it stops with failure

Makefile:225: die Regel für Ziel „crypto_openssl.lo“ scheiterte
make[2]: *** [crypto_openssl.lo] Fehler 1

I tried with OpenSSL 1.0.1t which is the actual version from Debian jessie

when trying to compile it. There is a gnutls version available at the repos but this seems not to work with letsencrypt. :(

Well, after going a bit offtopic, I just posted my howto for the btrfs raid 1 here http://forum.doozan.com/read.php?2,33146,33146#msg-33146

happy hacking,

Hi guys,

thank you both for the quick replies and thank you saschadd for the excellent tutorial. For the moment I solved the problem in the "brutal" way. Thanks to saschadd, my attention focused on the «local-premount/btrfs» file. In my case it was not missing, and the content matched with this one: http://askubuntu.com/questions/829205/stuck-in-initramfs-with-btrfs-root-array

But I noticed that on my Raspberry Pi 3 (with external USB enclosure with 2x WD RED 3Tb hdd in btrfs RAID1) the "btrfs device scan" output was printed just before USB devices appeared.

So when I was dropped to (initramfs) I just did:
1) a device scan manually
2) mount the raid
3) chroot into the rootfs
4) edit /usr/share/initramfs-tools/scripts/local-premount/btrfs (god bless chroot maintainers and a little bit less initramfs maintainers that don't even ship nano with it) adding these lines to the bottom:

echo "----------------- Waiting 30 seconds for USB to become ready... -----------------------"
sleep 30

if [ -x /bin/btrfs ]
then
echo "----------------- Re-doing btrfs scan -----------------------"
/bin/btrfs device scan 2> /dev/null
fi

5) run update-initramfs -k -u `uname -r`
6) got tons of errors because I forgot to mount /proc /dev /sys and /run, so went back to step 3) and did everything again
7) forgot to mount /boot/firmware so went back again and did everything again
8) uncompressed both old and new initramfs-es (with gzip -d and cpio -i < uncompressed_initrd) to check that everything was ok
9) rebooted for the tenth time and it finally worked

For the moment (= until 18.04 arrives) I'll stay with this workaround. I know that it's really not update-proof, but I already lost many hours on this so, well, it's perfectly fine :)

Thank you again!

Cheers
Avio
