Jetson TX2 rebooting due to corrupted rootfs - any pointers to recover it?

Autonomous Machines Jetson & Embedded Systems Jetson TX2
1

Hi All,
Our NVIDIA Jetson TX2 board has been rebooting continuously with the following message during startup.

Looks like the rootfs is corrupted and some mount points and files are missing from it.

Could you provide info on how the board can be recovered?

I would like to know the full approach from you so that I can bringup the board without any issues.

Are you positive the file system didn’t just fill up? Writing necessary temp files can cause some unexpected failures when the file system is full.

First, you may be interested in cloning the root partition (the “APP” partition). You can loopback mount this and see if it is corrupt during the mount operation. If not, then you can also use “df -H” on the mount point and see if it is full. TK1 clone information is good, but the specific clone procedure differs from a TX2. The TK1 clone info is here:
[url]http://elinux.org/Jetson/Cloning[/url]
…the TX2 procedure:
[url]https://devtalk.nvidia.com/default/topic/1000105/jetson-tx2/tx2-cloning/[/url]

Note that there is a patch for the flash.sh there (it adds the “-G” option for cloning). There is a new release which just came out today which probably fixed this (was R27.1, today you can now flash R28.1). See:
[url]https://developer.nvidia.com/embedded/linux-tegra-archive[/url]

When you flash you have the option of generating a new image…this is the default. You can also choose to “reuse” an old image, and this saves time. The clone can be used for the “reuse” option…if it is just a full file system then you can save everything and flash with the fixed clone.

Some cheat sheet notes for command line flash:
[url]https://devtalk.nvidia.com/default/topic/1001583/jetson-tx2/jetson-tx2-not-recognized-installation-inside-docker-error-8-error-return-value-8-command-tegrarcm_v2-chip-0x18-rcm-rcm_list_signed-xml-skipuid-reading-board-information-failed-/post/5116716/#5116716[/url]

Much of this is done for you if you use JetPack (a front end for flash and extra package installs).

The above approach worked. Thanks for the directions!

@MoBah, has your problem returned at all? I have a similar problem and have seen it on a couple of different TX2s. I’m trying to narrow down if it is a power supply problem, a software problem or something else.

5

This means that the file system could not be read, or if it was read, it was incomplete or corrupt.
The “/sbin/init” executable is the first program that the kernel starts, it gets PID 1 and lives for as long as the machine is up.
If that’s not there or readable, nothing will work. The reason for it not being there/readable may be harder to figure out – but it’s typically a botched root file system.

6

Losing “/sbin/init” would tend to imply the file system could not be mounted at all. Don’t think of this file as being an issue, think of the entire rootfs image being unmountable and in need of repair. Which L4T version is it, e.g., R27.1 or R28.1? For R28.1 the driver package had the needed changes for cloning added to it without a need to patch flash.sh (you can check the official Documentation downloaded with R28.1 for the steps…there might be some changes versus earlier releases).

7

My problem was similar in that the Jetson ultimately got stuck in a reboot loop. My /sbin/init is was fine as far as I know. I’m using 27.1, but in an effort to recover some files from the Jetson in question, I did patch flash.sh and read the flash. Using fsck I found that the file system was definitely corrupted. I confirmed this by looking at the /var/log/syslog (pasted excerpt from beginning). For this particular log, the boot hung at ~15s on a line related to the USB drivers. I was able to re-flash the Jetson and use for a half day, but then it failed again when I came in the next morning… this time in a reboot loop for which I don’t currently have the flash contents. I’m starting to think I need to take a careful look at my lab power supply to see if it is causing my recurring problems with the flash.

When the unit is intentionally shut down, how is it accomplished, e.g., via “sudo shutdown -h now”, or the GUI shutdown button? Direct hard power down by button would cause corruption similar to a failed power supply.

9

For the setup where the device failed, I typically use the GUI shutdown button.

When using SSH, I typically use “sudo poweroff,” but that was not the case here.

10

While this is true, the only “corruption” this should cause on an ext4 file system is that any data written but not flushed will be lost from within modified files.
ext4 uses journaling to make sure files don’t go missing when power failures happen, and the file system should not become corrupt from any instantaneous power failure event.

What can corrupt an ext4 file system is:

  1. Bad flash blocks. If a flash page fails catastrophically without the ECC being able to recover it, the flash controller can re-map this block to somewhere else if you re-write it, but the data in the block will be lost.

  2. Stray kernel memory pointer writes (driver bugs.) If you corrupt the data to be written to the file system, and then actually write that corrupted data, then the file system will become corrupt.

  3. Drivers or hardware that lie to the kernel. The kernel depends on ordered writes “taking effect” in order. If kernel writes block A, then block B, then block C, and the driver/hardware acknowledge the secure storage of each of these blocks in order, the kernel assumes that they committed in that order. If, for example, the flash controller re-orders blocks, and power fails, and it turns out B and C committed but A didn’t, the kernel will be confused and the file system may become corrupted.

  4. Bad disk or out of disk space when creating the initial file system image. Even if there’s a “failure” creating the file system image, the flashing toolkit may not discover this, and the corruption may lie latent in the file system image on disk until some particular event / write happens, at which point things start blowing up.

There’s not a lot you can do about 2. and 3. yourself (unless there is a bug in a driver that you’re developing yourself!) but you can easily investigate and fix 4. and perhaps also get some insight into 1. with some diagnostics. If the error happens multiple times, it’s less likely to be 1. unless the flash memory was damaged somewhere between fab line and your desk.

11

For #1, I was thinking to run “badblocks” in the default read only mode.

For #4, I ran “fsck.ext4 -nf system.img.raw” on my cloned image. It showed 0.3% non-contiguous files, but otherwise clean file system. Also, I’ll pay closer attention fsck results at boot next time.

Was this what you were thinking for investigating these issues?

Since the flash is always mounted on the Jetson, I can’t figure out a great way to run file system diagnostics. Everywhere I look says to run these types of things from the Live CD. Is there something obvious I’m missing for how to do this on a Jetson?

12

You can create an SD card for running fsck.ext4 from. I add an entry to extlinux.conf and then use serial console to select it at boot time. If you don’t have a serial console or you haven’t planned ahead and added the SD card alternate boot entry it gets more complicated. Something I suggest every Jetson owner do as an edit to their eMMC “/boot/extlinux/extlinux.conf” is copy the default entry “primary”, and make a duplicate below this with the following edits to the duplicate:

  • Rename LABEL to sdcard
  • Rename MENU LABEL to sdcard (or whatever you want).
  • Change "root=/dev/mmcblk0p1" to "root=/dev/mmcblk1p1".

If you have a USB hard drive (SATA) you might also add a similar entry with “/dev/mmcblk0p1” replaced by “/dev/sda1”.

With those in place you will still default to eMMC, but the entry will be there for alternate select via serial console should anything go wrong (it’s difficult to edit the file if the system won’t boot).

In a case where you have eMMC but did not make this edit you may have problems…but in a case where eMMC is corrupt and won’t mount it may be the boot loader continues looking for bootable devices and a rescue SD card will be detected anyway (or rescue USB hard drive).

Here’s some info for one way to deal with rescue (there are a lot of different ways to do this, the way which works depends on situation):
https://devtalk.nvidia.com/default/topic/1018963/jetson-tx2/jetson-tx2-doesn-t-startup-after-installing-tensor-flow/post/5188175/#5188175

The gist is that you copy the sample rootfs to the first partition of the rescue device via “sudo”, and that partition should be a native Linux type (“ext4” is guaranteed). If your host has some 64-bit extensions in mkfs.ext4 the extensions must be turned off (explained in the above URL…this is usually not required) during creation of an ext4 partition. Then you use “sudo” to name this partition as the alternate location of the “apply_binaries.sh” script (the “-r /where/ever/it/is/mounted” option). After you edit the SD card’s extlinux.conf to point at mmcblk1p1 you are ready to try.

I happen to do something similar with a clone or backup image instead of just the sample rootfs. It has my ssh keys in place, it has network setup in place…it just works without fuss. It also makes a backup image I can flash from if I lose the backup on my host.

Another rescue option is to clone the eMMC root partition (a very slow process), followed by repair of the partition on the PC host while the clone is covered by loopback (not difficult once you have the clone), and then flash again reusing the clone instead of a new system.img.raw (slow, but not as slow as a full flash).

Having a serial console is a “must” if you want to do efficient work when alternate boots are to be tested…or during rescue.

13

Yes, you can flash to an sdcard, using mmcblk1p1 as the target device.

Best way to create an sccard is likely to use a 32 GB or bigger sdcard, and clone the entire internal flash to the card:

dd if=/dev/mmcblk0 of=/dev/mmcblk1 bs=8M

Then, create a new entry in extlinux.conf to be able to boot from the SDCard; you’ll need to select it within seconds of boot on the serial console.

Separately, “badblocks” won’t help much, because once the flash controller sees a bad block, it will re-map it to a good spare block, but the data in that block will be lost if the ECC isn’t good enough. Re-scanning for “bad” blocks won’t find it, because it’s been replaced.

In fact, “badblocks” on flash media will needlessly stress the write cycle count of that media, so I wouldn’t recommend it.

I wonder if the flash controller has some insight/logs into its behavior, so you can tell whether bad things have happened in the past? I checked with smartmontools, but it doesn’t expose SMART counters that I can tell.

14

Thanks for the advice. I was able to re-flash the Jetson to get it running long enough to configure it to boot from an SSD. I ended using my host to copy my clone (system.img.raw) to the SSD using “cp -ax.” This was the simplest method for me. I cleaned the filesystem errors off of mmcblk0p1, but since I’m in the middle of a critical data collection and it is working on the SSD, I’m holding off further testing on the flash until probably next week sometime.

My current thinking is that there is something wrong with my sparse clone image. Before cloning the Jetson, I’d been using it for a while so I thought I’d clean up the unused flash by filling it with ones (assuming that is the default erased values)

tr '

tr ‘\0’ ‘\377’ < /dev/zero | dd bs=64K of=ones.file
rm ones.file

' '77' < /dev/zero | dd bs=64K of=ones.file
rm ones.file

It seemed that mksparse assumed the fill pattern was zeros so I had to manually create the sparse image

sudo ./mksparse -v --fillpattern=255 system.img.raw system.img

My best guess is that screwed something up because every Jetson I clone only works for a little while, but I can’t find any filesystem errors on the .raw file. I’ll try to post here if I ever get to the bottom of it.

Thanks again for your help.

Just so you don’t do more work than needed, you don’t need a sparse file to flash with. The original flash software used only the raw file named as system.img. It was later on (probably due to flash taking so long) that flash.sh started renaming system.img to system.img.raw, and then using mksparse. “system.img” will be flashed correctly regardless of whether it is raw or sparse. Skip the sparse file conversion and just flash (this takes a lot longer due to USB2 having more data to transfer, but it works). This started on the TK1, here’s a short blurb on it, including use of NULL bytes for the pattern:
[url]Jetson/Cloning - eLinux.org

16

The default value for sparse files does not depend on the specific media (such as flash) default bit patterns.
It’s the file allocation information that makes the file “sparse” – it’s not just that they seek past the current write point, it’s that the file block map doesn’t even include blocks for certain ranges, and the kernel will then fill in zeros for those.

If you use a file system that does not support sparse files, then the sparse files won’t work. Make sure your host is installed on ext4 or a similar sparse-capable file system!

17

Finally got a chance to look into this further (it was working well booting from the SSD, so I left well enough alone for a while). @linuxdev, flashing with the raw file worked great… no flash errors… thank you!!!

@snarky, I’m not sure mksparse is actually taking the file allocation information into account (it would make a lot of sense if it did though). The reason I say that is because I tried running the following two commands today:

sudo ./mksparse -v system.img.raw system1.img
sudo ./mksparse -v --fillpattern=255 system.img.raw system2.img

system1.img was 28.9 GB and system2.img was 17.5 GB. If it was taking into account the file allocation information, those files should be the exact same size. Remember that I filled the empty flash with 0xFFs prior to reading the image off the device, so I’m not surprised that the fillpattern=255 command resulted in a smaller image. Any further thoughts?

18

Try “–fillpattern=0” as another comparison…I think this is what the flash script uses.

19

As you predict, I get the same results (28.9 GB) when I use either of these commands:

sudo ./mksparse -v system.img.raw system1.img
sudo ./mksparse -v --fillpattern=0 system.img.raw system3.img
