February 8, 20206 yr Hi, Twice in the last week my unraid box has done a hard crash in the early hours of the morning. As in, blank screen, non-responsive, needs a reset. The difference this morning is that i had set the syslog set to write to the disk so i have the log....but i'm not seeing anything useful in it. In fact, there's an entire gap of time in the log, strangely enough. 3:10am you can see the CA Backup/Restore running and completing. ...Nothing in-between... 7:02am the drives spin down down. ...Nothing in-between... 9:13am you can see the system start to come back up (or maybe from before when i plugged in a keyboard, its hard to tell as the log doesn't specifically show what i would expect to see during a boot at the beginning). Looking over the logs, SMART statuses & both an hour before and then after the reboot shows no errors that i can see either. The only 'theory' i have is that according to the time schedules i have for mover, backups, etc. the appdata backup runs about an hour before the mover, but i dont see a mover entry in the log... How do i go about diagnosing this further? As its previously ran for close to a month without a single issue (all new hardware/new build).

February 8, 20206 yr Author This topic sounds similar in some ways: However i do not use a Melanox NIC, just the onboard. Found this by seeing a warning error a recent log showing: kernel: igb 0000:03:00.0 eth0: mixed HW and IP checksum settings. May be completely unrelated though...

February 9, 20206 yr Author Thanks, will read that in a moment....as luck would have it, time of day aside, I managed to catch it in action, with an error. It's a kernel panic!
