unRAID 6.8.3.

 

Few weeks back, I posted back about the random hangs.  At the time, it seemed like my sole Win10 VM was the cause.  Disabling the VM from running (not on boot, turned off when not in use) seemed to have helped, but the hangs still appear.  Had my unRAID machine on for nearly 3 days, then it just went unresponsive about three minutes ago.  Heat definitely isn't the cause, as it's still early in the morning, and the previous two days haven't been all that warm.

 

I've re-enabled local syslog server, writing to system, and mirroring to flash.  Where on flash, can I look at the log file for any clues on crashes?  These random hangs are bugging me to no end!

Is the USB filesystem mounted on boot?  I've had this enabled, but I don't see a logs/ folder anywhere that is mounted, and I've scanned anything obvious that is mounted with 'mount'.

Here is the full path to it using SSH or the GUI terminal.  IF you share/export the Flash Device (   Main   >>>  Boot Device ---> click on Flash  >>>  SMB Security Settings  ), you can access it via Windows Explorer.

 

ls -al /boot/logs

Thank you!  Now I await another crash.  Could be today, could be Monday.  Let the dice roll begin!

Crashed last night, powered it off, and here are the last lines in the log file before the crash and this mornings boot:

Unfortunately there's nothing in the log that gives a clue about the crash, it could be a hardware issue.
