Help needed with unclean shutdowns


Go to solution Solved by JorgeB,

Hi, After building my unRAID server at the start of this year, I've had a few unclean shutdowns.  After looking through my syslogs It seemed to me (a complete noob), that something was happening with disks.  So, after adjusting a few things (minimum free space and spin down delays), everything has been working well for 1-2 months.  Today however, I had another unclean shutdown.  I think my parents were trying to stream a large movie in my library through Plex at the time.  The last entry in syslog was

but I'm not sure if this has anything to do with what happened.

 

I've attached the diagnostics obtained after the shutdown, and 2 syslog exports (1 including logs upto the shutdown, and 1 including the boot after as I noticed some errors after I'd restarted my server.

 

I'd really appreciate any advice anyone can offer.

 

Many thanks!

Do you mean the server crashed or rebooted on its own?

Hi,

 

I could no longer access anything on the server (GUI, Plex, Apps etc.). The light on the server was on, but it was completely unresponsive.  I couldn't shut it down without holding the power button in for 5 seconds.  Then, once it restarted, I could access the GUI and had to start a parity check.

 

Thanks.

Yes, that's fine, unfortunately there's nothing relevant logged, this usually points to a hardware issue, one thing you can try is to boot the server in safe mode with all docker containers/VMs disabled, let it run as a basic NAS for a few days, if it still crashes it's likely a hardware problem, if it doesn't start turning on the other services one by one.

OK, Thanks for taking the time to have a look.  It’s been running fine for probably a couple of months since the last crash.  I’ve been looking through Plex’s logs too, but can’t see anything around that time either.  I’d previously set a RAM disk up for transcoding, but around the time of this latest crash would have possibly been the first time it’s been used, as I’ve just been watching on my network.  I’ll do some testing and see if I can replicate.

 

Thanks again for your time 👍
