Hi all!

 

So, for the last little while now, Unraid 6.1.x has been crashing on me unexpectedly.  Since upgrading to 6.1.6, at least the GUI crashes (partially) and I can access the terminal prompt, but the server goes off-line.

 

I'm not sure what's causing this, but here's the syslog (attached) and a screen shot of the gui when it's dead, as well as a screen shot of the terminal when I've issued the powerdown script.

 

Any idea which "device" that Powerdown complains about?  Also, in the syslog, it complains that the mover has no space... I'll have to look at that drive to see if there is no space there.

 

Thanks in advance!

syslog.zip

In the meantime, what does "df -h" and "df -h /" produce?

 

Also going forward, always try using the command "diagnostics" to produce a zip file that contains more information, such as what processes are running, it will also include disk share information and what you may be running from the go script. This will create a zip file under /boot/logs/machinename-diagnostics-yyyymmdd-HHMM.zip .

 

 

I dont know if powerdown is having issues with a full log (/var/log/) or a full USB Flash drive (/boot).

 

You're running out of ram on /var/ filesystem.

 

Also on the last day, mover complained about some filesystem running out of space as well. Line 44 writes to the /var/run/mover.pid file. If your /var/run is running out of space then essentially you're running out of RAM since /var/ is located in RAM.

 

You need to do some of the following:

• Add more RAM to your system.
  
• Figure out what docker or other process is writing to the /var/ filesystem instead of on your cache drive or array drives.
  
• Stop using as many plugins as you're using.
  

 

 

Jan  6 03:40:01 Tower logger: /usr/local/sbin/mover: line 44: echo: write error: No space left on device

 

Also log rotate aborted abnormally, not sure why:

 

Jan  6 04:40:01 Tower logrotate: ALERT - exited abnormally.

 

Your syslog does indicate you had (have?) some errors with your BTRFS on /dev/sdn1.

You're running out of ram on /var/ filesystem.

 

Ah, well, maybe that's because in my go file has a line in there:

# resize tmpfs
mount -o remount,size=1024m /var/log

 

That was put in there due to an earlier suggestion to increase it as I have been having this problem for awhile.

 

Here's the output from df -h and df -h /

I notice that my syslog file is growing hugely, and I'm uncertain as to why.  Would certainly contribute to a lack of space!

 

But certainly the /var is something that I need to correct.

 

How do I get Docker to use /var on the cache drive?

 

Thanks!

 

Hm, looks like my log filled up due to Supermicro's IMPI fighting with Sensors module of the kernel:

Jan  7 05:23:09 Tower kernel: w83795 0-002f: Failed to read from register 0x011, err -6

Jan  7 10:00:41 Tower kernel: i801_smbus 0000:00:1f.3: SMBus is busy, can't use it!

 

I googled around, and the W83795 is the chip my supermicro board uses, and feeds into libsensors.

 

The filling up of the log with the "Failed to read from register xxxxx" error is, according to this a german site:

... because of the built- in attempts Supermicro IPMI simultaneously on the I2C ( SMBus ) access . Either disable the sensor module or IPMI .

 

Haven't seen this before in the logs, so I'll remove these lines from my go script since I'm not using the sensors plugin anymore:

 

# Added for Sensors:
modprobe coretemp
modprobe jc42
modprobe w83795
/usr/bin/sensors -s

 

We'll see what happens after this!
