Diagnostics when server hard locks?

[Ystebad]

I am having problem with my unraid server crashing 1-2x weekly.  when it locks up it completely logs up and I can't ssh in or access on the machine itself so I can't generate a diagnostics file.

 

Is there a way to enable detailed logging that gets permanently written or to access information to help figure out the problem after a reboot is required, because when the machine crashes I can't do anything but completely reboot?

 

Very frustrated at this problem, I've had to run parity check on an unclean shutdown like 4 times in the last 2 weeks on 16 drives - takes like 20 hours each time.

Enable the syslog server (settings-->syslog server) and set it to mirror to the flash drive.  If mirrored to the flash drive all the information captured in the syslog is not lost on a reboot.

 

Here are some good instructions for setting up a syslog server.
