Random reboots*


#1

I have the Omnia 2GB in the NAS case with two HDDs attached. The device reboots randomly about once a day or so. I usually only notice that because my lxc containers are down.

Any ideas on how to debug this? Are the logs from the previous session available anywhere? Everything under /var/log seems to be from the current session only.


#2

/var/log is in a tmpfs by default, so it’s non-persistent. (The reason is as usual – not to destroy the internal flash too soon.)


#3

That makes sense and I had gathered as much. So, any recommendations on how to go about finding out what’s happening here? This is starting to be rather frustrating.


#4

Hello @Manul,
in this case, it seems that you need to have serial cable, which you can connect to your Turris Omnia.

I’d need the output from the serial console, what’s is going on.
Maybe diagnostics can help you in this case, but before restart or have it at least running for a day would be great. Diagnostics contain sensitive data and they shouldn’t be uploaded to some cloud or to be available to download for everyone on some file hosting. You need to send the diagnostics in attachment to email address: tech.support@turris.cz


#5

Is this really the only possibility? Is this diagnostic data only given out via the serial console? Is there no internal/software way to redirect or duplicate it to one of the HDs?


#6

Serial console might be your best bet regardless. That would be the most basic hardware interaction. Writing to hard drives or to an external host via syslog requires drivers and the OS to be up and functioning. I believe the serial console runs from power on.

You can try forwarding your logs to an external log server as I do. I created “/etc/syslog-ng.d/remote.conf” with the following:

destination d_loghost { udp("192.168.1.12"); };
log {
        source(src);
        source(kernel);
        destination(d_loghost);
};

Where 192.168.1.12 is my main server that’s also running syslog-ng.

However, that only captures stuff that happens when syslog-ng is running. There are many things that syslog does not capture.

On the other hand, if you run a serial cable, you will see every console related action including most hardware issues and the complete boot sequence and should see any messages sent by the kernel indicating there’s a problem.

My server runs Linux and I currently run screen to log serial interactions (for something else) since screen also allows me to interact with the terminal more or less normally and detach from it when it’s not being used. Probably something like this (once you have the proper serial cable)

/usr/bin/screen -L /dev/ttyUSB0 115200,cs8

If you’re a Windows user you’d use something like Putty, but that’s beyond my area of knowledge.


#7

Well currently I’m looking for the reason why the router crashes. I guess that happens at a stage when the OS has been up and running for a while, otherwise I would have noticed earlier.

I’m still hesitant to buy an extra cable. I’ve been administering Linux machines for a while now, and so far I have always been able to find reasons for crashes from some log files without having to monitor the system realtime to capture the moment of the crash.

Maybe I’ll give syslog-ng a try although that still seems overly complicated to me. I was thinking of running something like tail -f /important/logfiles > /file/on/hd but I would somehow have to cope with log rotation.


#8

Doing something like tail -f /important/logfiles > /file/on/hd sometimes (often?) doesn’t catch the important last thing that causes the crash.

Mostly due to final writes being lost in cache’s while the hardware is busy restarting and wiping the RAM. With lots of calls to sync you might avoid that.


#9

take a look at /etc/syslog-ng.conf. I think you can easily setup syslog to other path.

destination messages {
	file("/var/log/messages"

Other than that, I can agree with points already wrote on this topic.


#10

Thanks, both of you. I have set up a second destination and remounted the partition it’s on with “-o sync”. Of course that’s no guarantee that I’ll actually catch anything, but I think it’s worth giving the search a try with what I have before I buy extra hardware – even if it’s only a cable.


#11

It’s been a while since I had time to look into this, but since the random reboots still happen (and are extremely annoying), I’ve investigated some more.

The reboots only seem to happen when an LXC container is running. The container in question lives on a SATA-attached HD and contains Logitech Music Server. When I set this to continuously play music from a different partition on the same HD, the Omnia reliably crashes after a couple of hours at most.

To investigate, I started a screen session on a different host and ran a “tail --follow=name /var/log/messages” in that. Here’s what I found in the log preceding the last crash:
