    RussianNeuroMancer reacted to m11k in HOWTO: btrfs root filesystem   
    Hi,
     
    I wanted to convert my root filesystem to btrfs.  This allows me to use snapper to take regular snapshops.  I also use btrbk to send my snapshots to my secondary storage (also a btrfs array).  My root filesystems is installed to eMMC, but there isn't any reason you couldn't do this with an sd card.  These instructions are done with a laptop running Linux.  I'm using Debian in this case, although any distro with a recent kernel and btrfs tools installed should work.
     
    CAVEATS:
    The current u-boot image (2020.08.21) doesn't support booting natively to btrfs.  u-boot *does* support btrfs though.  Hopefully a future build of u-boot will add btrfs support.  To work around this, we have to create an ext4 /boot partition, and then a btrfs root partition.
     
    1. To start, I booted the helios64 via sd card to the USB mass storage image (https://wiki.kobol.io/helios64/install/emmc/).  I then connected a laptop to the helios64 via the USB-C cable, and the emmc appeared as /dev/sdb.  The rest of these instructions will assume the eMMC is /dev/sdb, so please adjust accordingly for your system.
     
    2. Mount the eMMC root filesystem on the host:
    # mkdir /mnt/nasrootext4 # mount /dev/sdb1 -o ro /mnt/nasrootext4  
    3. Back up the contents of the root filesystem:
    # tar -C /mnt/nasrootext4 --acls --xattrs -cf root_backup.tar .  
    4. Make a backup of the partition layout (in case you decide to revert this modification):
    # fdisk -l /dev/sdb | tee nas_fdisk.txt  
    5. Unmount the filesystem, and run fdisk on it.  Make note of the start sector.  It should be 32768.
    # umount /dev/sdb1 # fdisk /dev/sdb Command (m for help): p Disk /dev/sdb: 14.6 GiB, 15634268160 bytes, 30535680 sectors Disk model: UMS disk 0 Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x794023b5 Device Boot Start End Sectors Size Id Type /dev/sdb1 32768 30230303 30197536 14.4G 83 Linux  
    6. Delete the existing partition ('d')
    7. Create a new partition ('n')
    8. Select 'primary' partition type
    9. Select partition number 1
    10. Select first sector: 32768 (This is very important to get right, and should match the start sector of the partition that was just deleted)
    11. Select last sector: +512M (this create a 512MB /boot partition)
    12. You will see a message "Partition #1 contains a ext4 signature.".  This is okay.  I selected 'n' (don't remove signature) but it doesn't matter.  You should probably remove the signature since we're going to create a new ext4 filesystem anyway.
    13. Create new partition ('n')
    14. Select 'primary' partition type
    15. Select partition number 2
    16. First sector: 1081344 (this is one more than the end sector of the other partition)
    17. Last sector: (leave the default as the full drive, 30535679 in my case)
    18. Print the layout to confirm:
    Disk /dev/sdb: 14.6 GiB, 15634268160 bytes, 30535680 sectors Disk model: UMS disk 0 Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x794023b5 Device Boot Start End Sectors Size Id Type /dev/sdb1 32768 1081343 1048576 512M 83 Linux /dev/sdb2 1081344 30535679 29454336 14G 83 Linux  
    19. Write the partition table to disk and exit ('w')
    20. Create a new ext4 filesystem on the first partition: 'mkfs.ext4 /dev/sdb1' (you may need to add -F if it complains about an existing ext4 signature)
    21. Create a new btrfs filesystem on the second partition: 'mkfs.btrfs /dev/sdb2'
    22. Mount the new root filesystem:
    # mkdir /mnt/nasrootbtrfs # sudo mount -o compress=zstd /dev/sdb2 /mnt/nasrootbtrfs  
    23. Make some initial subvolumes (note that '@' will be the root subvolume, as this is preferred by 'snapper'):
    # cd /mnt/nasrootbtrfs # btrfs subvol create @ # btrfs subvol create @home # btrfs subvol create @var_log  
    24. Mount the boot partition, and the @home and @var_log subvolumes
    # cd @ # mkdir boot # mount /dev/sdb1 boot/ # mkdir home # mount /dev/sdb2 -o noatime,compress=zstd,subvol=/@home home # mkdir -p var/log # mount /dev/sdb2 -o noatime,compress=zstd,subvol=/@var_log var/log # mount | grep sdb /dev/sdb2 on /mnt/nasrootbtrfs type btrfs (rw,relatime,compress=zstd,space_cache,subvolid=5,subvol=/) /dev/sdb1 on /mnt/nasrootbtrfs/@/boot type ext4 (rw,relatime) /dev/sdb2 on /mnt/nasrootbtrfs/@/home type btrfs (rw,noatime,compress=zstd,space_cache,subvolid=258,subvol=/@home) /dev/sdb2 on /mnt/nasrootbtrfs/@/var/log type btrfs (rw,noatime,compress=zstd,space_cache,subvolid=260,subvol=/@var_log)  
    25. Note that our current directory is '/mnt/nasrootbtrfs/@'
    26. Untar the old root filesystem into the new root directory.  Since boot, home, and var/log are mounted, tar will extract the relevant data into these mounted filesystems.
    # tar -xvf /root/helios64_root.tar --acls --xattrs --numeric-owner |@ tee /root/extract_log.txt This is the only spot where things did not go as expected.  I received a handful of errors about "No space left on device" while untarring.  These seem to be transient btrfs errors. I use btrfs pretty extensively at work, and I've seen cases in the past on older kernels where btrfs would falsely report ENOSPC when the filesystem was under heavy load.  I'm not sure if that is what is happening here, but I would guess it's a bug.  It could be a bug in the kernel on my laptop, or it could be a bug in the usb-c mass storage export on the helios64.  To recover from this, I ran the tar command a couple of times.  I continued to receive these errors on different files.  I did this three or four times.  I also tried removing --acls and --xattrs, but it didn't seem to make much of a difference.  On my last attempt to untar, all of the files that failed happened to be from usr/lib/python3, so I untarred just that directory: 'tar -xvf /root/helios64_root.tar --numeric-owner ./usr/lib/python3'.  That extracted without error.  I was satisfied that everything made it back on disk.  Perhaps if you only extracted one top-level directory at a time, it would not produce any errors.  Maybe there is some way to slow down the 'tar' to avoid these ENOSPC errors.
     
    27. After extracting the root filesystem, I made a snapshot of it: 'btrfs subvol snap -r . root_post_copy'
    28. Update /mnt/nasrootbtrfs/@/etc/fstab.  This was my old fstab:
    Old version: UUID=dabb3dbf-8631-4051-a032-c0b97eb285bd / ext4 defaults,noatime,nodiratime,commit=600,errors=remount-ro 0 1 tmpfs /tmp tmpfs defaults,nosuid 0 0 # >>> [openmediavault] /dev/disk/by-label/helios64_btrfs_raid1 /srv/dev-disk-by-label-helios64_btrfs_raid1 btrfs defaults,nofail,noatime,nodiratime,compress=zstd 0 2 # <<< [openmediavault]  
    Look up the new UUID for /dev/sdb2.  I did this by running 'ls -l /dev/disk/by-uuid').  Updated /etc/fstab:
    UUID=240bab7d-1b6c-48f4-898d-ba12abcecb3f / btrfs defaults,noatime,compress=zstd,ssd,subvol=@ 0 0 UUID=240bab7d-1b6c-48f4-898d-ba12abcecb3f /home btrfs defaults,noatime,compress=zstd,ssd,subvol=@home 0 0 UUID=240bab7d-1b6c-48f4-898d-ba12abcecb3f /var/log/ btrfs defaults,noatime,compress=zstd,ssd,subvol=@var_log 0 0 UUID=fd5b620c-57e2-4031-b56c-3c64ce7c7d5f /boot ext4 defaults,noatime 0 2 tmpfs /tmp tmpfs defaults,nosuid 0 0 # >>> [openmediavault] /dev/disk/by-label/helios64_btrfs_raid1 /srv/dev-disk-by-label-helios64_btrfs_raid1 btrfs defaults,nofail,noatime,nodiratime,compress=zstd 0 2 # <<< [openmediavault]  
    29. Modify /mnt/nasrootbtrfs/@/boot/armbianEnv.txt.  In particular modify rootdev, rootfstype, and add 'extraargs'.  Old version:
    verbosity=1 bootlogo=false overlay_prefix=rockchip rootdev=UUID=dabb3dbf-8631-4051-a032-c0b97eb285bd rootfstype=ext4 usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u  
    New version:
    verbosity=1 bootlogo=false overlay_prefix=rockchip rootdev=UUID=240bab7d-1b6c-48f4-898d-ba12abcecb3f rootfstype=btrfs usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u extraargs=rootflags=subvol=@  
    30. Make a 'boot' symlink.  I'm not sure if this is necessary, but u-boot expects the boot files to be in the '/boot' directory on the root filesystem, but they are now in the root directory of the boot partition.  This symlink makes sure that if u-boot tries to access /boot/foo, it will actually access /foo.
    # cd /mnt/nasrootbtrfs/@/boot # ln -s . boot  
    31.  Unmount everything:
    # umount /mnt/nasrootbtrfs/@/var/log # umount /mnt/nasrootbtrfs/@/home # umount /mnt/nasrootbtrfs/@/boot # umount /mnt/nasrootbtrfs/  
    32. Power off helios64
    33. Remove sd card
    34. Start picocom on your laptop ('picocom -b 1500000 /dev/ttyUSB0')
    35. Turn on helios 64 and look for startup.
     
    TROUBLESHOOTING:
    Of course this did not work on the first attempt for me.  After rebooting the helios64, it never successfully booted into Linux.  I didn't see any errors from u-boot.  To troubleshoot, I wrote the original helios64 debian buster image to sd card and booted the helios64 to that.  I mounted /dev/mmcblk1p1 to /mnt, and changed the 'verbosity' to 7 in armbianEnv.txt.  I eventually discovered that I had the UUID wrong in /boot/armbianEnv.txt.  Correcting that value fixed the issue, and the helios64 booted successfully from eMMC.
     
    SETTING UP AUTOMATED SNAPSHOTS AND BACKUPS:
    Enabling 'snapper' for automated root snapshots was very easy:
    1. sudo apt install snapper
    2. sudo snapper -c root create-config /
     
    The debian snapper automatically take snapshots before and after apt upgrades.  However since /boot is a separate filesystem, this is not included in these snapshots.  As a workaround, I added an apt hook which rsyncs /boot to /.bootbackup before the snapshots are made.  Note that the 'snapper' hook is /etc/apt/apt.conf.d/80snapper, so I created /etc/apt/apt.conf.d/79-snapper-boot-backup:
    # /etc/apt/apt.conf.d/79-snapper-boot-backup DPkg::Pre-Invoke { "if mountpoint -q /boot && [ -e /.bootbackup ] ; then rsync -a --delete /boot /.bootbackup || true ; fi"; }; DPkg::Post-Invoke { "if mountpoint -q /boot && [ -e /.bootbackup ] ; then rsync -a --delete /boot /.bootbackup || true ; fi"; };  
    This takes care of automated snapshots.  I still want snapshots stored on another drive (or another system) for redundancy.  I'm using 'btrbk' to do this.  btrbk wants the btrfs top-level subvolume mounted somewhere.  To do so, I created the directory /mnt/btr_pool, and added the following line to /etc/fstab:
    UUID=240bab7d-1b6c-48f4-898d-ba12abcecb3f /mnt/btr_pool/ btrfs defaults,noatime,compress=zstd,ssd,subvolid=5 0 0  
    My spinning drive array on the helios64 is a btrfs filesystem, and I have it mounted on /srv/dev-disk-by-label-helios64_btrfs_raid1.  I created a '/srv/.../backups/helios64/btrfs/volumes' directory.  I then created the following three files:
     
    /srv/dev-disk-by-label-helios64_btrfs_raid1/backups/helios64/btrfs/btrbk.conf:
    timestamp_format long volume /mnt/btr_pool snapshot_dir btrbk snapshot_preserve 30d snapshot_preserve_min latest target_preserve 7d 8w 6m target_preserve_min latest target send-receive /srv/dev-disk-by-label-helios64_btrfs_raid1/backups/helios64/btrfs/volumes subvolume @ subvolume @home subvolume @var_log  
    /srv/dev-disk-by-label-helios64_btrfs_raid1/backups/helios64/btrfs/rsync_boot.sh:
    #!/bin/sh set -e -x mountpoint /boot [ -e /.bootbackup ] rsync -a --delete /boot /.bootbackup  
    /srv/dev-disk-by-label-helios64_btrfs_raid1/backups/helios64/btrfs/run.sh
    #!/bin/bash set -e -x CDIR=$( dirname ${BASH_SOURCE[0]} ) ${CDIR}/rsync_boot.sh btrbk -c ${CDIR}/btrbk.conf run  
    I then added a daily cron job which runs the 'run.sh' script.
     
    Well, that was a longer post than I had imagined.  I hope someone finds it helpful.

    I will just add a bit more. 
     
    We want to rewrite / make this from scratch with Ansible. Basically we seek Ansible expert or someone who wants to become one.  We have this know-how but we are simply too overloaded to move on. This is yet another job for common good! To make Armbian support better. To make Debian support better. To make Arch better, OpenWrt, ... To make every Linux distro out there running better on your board.
     
    The person(s) should focus only on testing. Creating and maintaining scripts for automated testing and later, when our support hardware is out of beta testing, implement that as well. It's a continuous project and will not end tomorrow. Also you don't need to stay on it forever. Do what you can. Help us get going ...
     
    We would like to automate:
     
    - initial board setup (after you flash the image, automated 1st login, setup network, different local repository, ...)
    - simple tasks such as upgrade, change to beta repository, downgrade to specific kernel, etc.
    - run various of tasks which can be added without limits
    - run various of benchmarks which can be added without limits
    - run tasks in parallel
    - make reporting in HTML, XML (common and per board)

    Most of those ideas are covered in some basic form in our first try: https://github.com/armbian/autotests

    The tag was always there but at a different configuration level so no need to change it manually ;-)
     
    Nonetheless the ideas to explore for this issue (which I will unfortunately have no time for in foreseeable future) would be:
    Disable HDMI support for rk3399 boards in u-boot again - something like this PR (may need adjustments)
    It was already disabled once because of similar issues (which were supposed to be fixed with v2020.07) but I am leaning towards disabling it for all rk3399 boards again; Blacklist panfrost module, reboot and see if it helps - there was quite some development in panfrost between 5.4 and 5.8
    This however does not apply to issues found in legacy; Try both of the above at the same time if none helps on its own; If you can spare some time - try testing the above scenarios.

    @0utc45t, try legacy image. if it still not working, make sure your cable has converter chip inside.
    There are at least 2 standards regarding display signal in USB Type-C. one is DisplayPort Alternate Mode, which is the one supported on Helios64 (RK3399) and the other one is HDMI Alt mode.
    If you have cable that use HDMI Alt mode, it won't work on Helios64.
     
    @RussianNeuroMancer,
    yes. on legacy, HDMI+Hub combo working fine. The problem with mainline driver, it does not support OTG. You have to define the port as "host" or "peripheral" in device tree.

    I the past few days I got several messages regarding this problem, even all corespondent knows that Armbian official policy only support images that are digitally signed. That is Armbian and its supported under those terms (make sure to read them before making more damages). Everything else you found floating on the internet you are using on your own risk. Why this topic? Since majority of R&D costs are covered from our private pockets (for official Armbian public share is between 0.2 and 0.4%),  most of your requests (for more of our private time/cash) can only ends in "f* off", "stop wasting our time", ... This is open source and "you", the one that need this and that function, full working and supported OS on every cheap garbage you purchase for a few bucks ... fork the code and maintain it! Armbian base maintenance (also source for TV boxes) currently costs us between 2.000 and 5.000 EUR per day and I have no idea how much people that fork this project adds that things also works (no idea how well) on TV boxes, that are similar to SBCs. If only 10% its already a lot! And what do they / we get back for that? Extreme constant demand and dissatisfaction since its absolutely not possible to fix all problems (for just 100 hours per day) and people doesn't (want to) understand that.
     
    We - Armbian - doesn't want to do anything with our forks - focusing to single board computers represent an insane big project, which we have already have big troubles to keep up. This policy is present since ever and for several months we are trying at least to do something about. Many people were investing their precious time into the project "What to do with TV boxes" to make this clear, to find best relationship and perhaps also support important Armbian forks in some way. Project is again 99.9% covered from our private pockets.
     
    If @balbes150 decided to stop supporting free of charge for you, for whatever reason, we have nothing to complain and I am sure we all fully support his decision but perhaps his Google translated words might scared you off. If he stop maintaining things, he is no longer responsible that boards breaks down. HW defects because of leaving off maintenance are extremely rare, but possible - I think he wanted to emphasize that. One doesn't need to add any evil code, hardware starts to break down when support is canceled, slowly but surely ... Besides, he is not to blame. Open source projects are done together - if you don't help him (and apparently you don't, with rare exceptions) and at least inspect and correct his work, why complaining and worrying about bad/evil code? Join development process and stop being cheap consumer who is complaining over the product he got for free.

    Make sure to check his (and also our) code and also perhaps understand that he might need a full-time assistant(s) to roll things out at the present level. If not, why the fuck anyone complains? There is a fork button.

    * Chrony can't start on platorms that map gettimeofday to clock_gettime64() * This is due to syscall filtering being correct on some but generic enough to cover all areas. as a temporary solution they wrote:
     
    So we will need to whitelist the clock_gettime64() system call in chronyd’s seccomp filter. I’ll send a patch upstream. Meanwhile, you can disable the seccomp filter by running (as root): # sed -i '/DAEMON_OPTS=/s/"-F -1"/"-F 0"/' /etc/default/chrony # systemctl restart chrony.service BTW: My NanoPi A64 with  armbian focal  kernel 5.6.12 is running
    chronyd v3.5-6ubuntu6 normally:

    I don't need this board working now 100% and it is also impossible to do that in a short time. Even if we put all our resources into it. It is also expensive and slow to bring this support from where it is now, to perfectly working. Since we pay for everything and you for nothing, we proceed with our speed. Until then we will only rely on upstream fixes (like everyone else), which will ofc takes months to emerge: keep updating and once it will just start working ...
     
    I have zero time to deal with this, nor is anyone dealing with this board to iron out those problems ... if you can't debug and fix some problem, forget it and use stock images which I assume might be better, but also not without bugs at this early stage. Usually it takes months to year that a board is production stable.
     
    Temporally closing this thread since this board does not have end user support. If you are not a developer, you can only help this way: https://www.armbian.com/donate or doing something else that is in the project interest.
     
    We haven't decide if we will pay the costs for dealing with you for this board which is on average around 20.000 EUR / year. You expect some real help or someone who has no clue about?
     
    Edit: I also manage to kill the only board.

    It is not so obvious  I only consider the state in the mainline kernel as a reference (because I decided for myself to track changes since 5.* only). And I see that USB Type-C controller changes its state from "host" to "gadget" and almost immediately powers off during the boot. It should be correctly handled automatically by the driver on this board according to my understanding. And forcing to host mode is imho just a workaround for some issue in the current driver (or some other problems in device tree).

    It was mentioned to me by email that the ethernet TX issue I describe here
    plagues this board as well (my board is the LibreComputer Renegade).
     
    It seems like the exact parameters might depend on each specific device, in which case the "best" solution would be some kind of "autoconfiguration" for the PBL, but that is in a future TODO. More about the issue andthe discussion here:
    https://patchwork.kernel.org/patch/10880481/
     
    Eventually this patch was merged for the Renegade upstream:

    The performance of RK3399 is very good and if you do not play Windows games, it is able to replace the average home PC with Linux. Even without the addition of HW support for full-screen video, (in SW mode) the rk3399 works seamlessly with the 1080 desktop in all modes and without brakes. Conclusion about the unsuitability rk3399 Linux - sheer stupidity or intentional deception. But it is important to understand that to get all the performance of this powerful processor, it and the whole system needs a good cooling system and a good medium (the device from which the system starts). Only in this case rk3399 will be able to show all his abilities. For example , you can take a shitty SD card and then yell that the system is slow compared to the Android system that is run from eMMC. Or use a bad cooling system. The main disadvantage rk3399 , it is a  heat at work, but with the release of rk3588 is significantly change.

    RussianNeuroMancer reacted to Igor in Summer update. Bust.er4all boards   
    v5.90 / 7.7.2019
    All images were updated. It mainly goes for a bugfix update, cleanup, adding Debian Buster release. Beware that software maturity with Buster is not just there yet (even it was declared stable) and with some applications (like OMV) you will encounter problems. Kernel/BSP wise, Debian Buster is the same, uses Armbian kernel, as our other builds. Most of the builds were briefly tested, but bugs might be hiding somewhere. This is the best what is out there thanks to greater Debian community, those around boards and of course ours which pushes generic Debian/Linux to the sky . Enjoy the summer time.
