unRAID server crashing

Hello, I have a small unRAID server which seems to locking up and I'm hoping someone can point me in the direction on how to diagnose.

 

When it locks up, I loose access to the unRAID web ui. If I SSH to the box, or physically login, then I can enter the username but unable to proceed to the actual command prompt.

 

I have enabled syslog writing to USB disk. 

 

This unRAID box runs a few docker containers (on various VLANs). There are no Virtual Machines.

 

I have replaced the USB flash but this didnt resolve my issue.

 

Many thanks,

Fraser

    Hi, can you also share that file if it covers a crash ? It is not included in the diagnostics.

    Ahh sorry, I didnt realise it wasnt included (im fairly new to unRAID)

     

    I hooked a monitor up to the unRAID box and noticed some BTRFS errors (attached) so I followed a guide to replace the docker.img. This was only this morning, when I made this post so still too early to see if that has resolved the problem yet.

    This machine used to run uBuntu server without any issues. The lockup issues only started since I reformatted and moved to unRAID.

    Hello, 

     

    Since replacing Docker.img, the crash happened again.

     

    Logs from syslog show the following:
