mustaqiim Posted May 24, 2017 Share Posted May 24, 2017 Hi guys, I was wondering if anyone know how can I diagnose this issue? (eg. getting logs before the unexpected shutdown). Lately, its been happening and I've changed my PSU too. Unraid only logs the moment the server restarts and nothing before that was saved :\ Thanks! Quote Link to comment
SFyffe Posted May 24, 2017 Share Posted May 24, 2017 This is a tough one to troubleshoot if nothing is logged. Did you try and reseat cards and cables and ram? I had a similar problem and it wound up being the thermal paste being dried out on the cpu heatsink. Maybe thermal shutdown of the CPU? Quote Link to comment
sevenz Posted May 24, 2017 Share Posted May 24, 2017 (edited) Same here, unclean shutdown detected. Had this issue since 6.3.3 (I just started with unRaid 20days ago). I changed motherboard (used the old HDD, RAM and USB for unraid) and still gets it. Tailed it and nothing. Changed PSU still the same. Having this issue like once every day. I will try to use 1 different RAM later and see if that helps. Edited May 24, 2017 by sevenz Quote Link to comment
Vr2Io Posted May 24, 2017 Share Posted May 24, 2017 For me, all system will first prove stable under Windows then put in unRAID, Windows have many tools for checking. Quote Link to comment
sevenz Posted May 24, 2017 Share Posted May 24, 2017 I came from Debian Wheezy, never had any crash before until I tried unRaid. Maybe I will try to boot no plugin no GUI to test if there is any crashes. Quote Link to comment

Install the fix common problems plugin and put it into troubleshooting mode. Logs and more will get saved onto the flash drive... Quote Link to comment

I realized the same thing too after i updated to 6.3.3 and same goes to 6.3.4, the server will barely last 3 days and it will unexpectedly shutdown and restart with a parity check. Didn't have this issue before this and it can run up to two months without restarting. 4 hours ago, Squid said: Install the fix common problems plugin and put it into troubleshooting mode.

As of now there's nothing much in my logs as errors before the shutdown are not captured. Will wait for the next crash and update here! Edited May 24, 2017 by mustaqiim Quote Link to comment
sevenz Posted May 24, 2017 Share Posted May 24, 2017 So I changed everything (motherboard, RAM, CPU, USB Flash disk) except the HDD and SSD, unfortunately still crash. No weird crash report captured so I have no idea. Mustaqiim you restarted with automatic parity check? Mine just stopped and I have to manually start parity check. Maybe can you post your plugins? Let's compare and see if we have similar plugins. As well as my setup. 1 Parity 4GB 2 HDD 4GB 1 SSD 128GB Plugins that I have: CA Auto Update Applications CA Backup / Restore Appdata CA Cleanup Appdata Community Applications Dynamix SSD TRIM Dynamix webGui Fix Common Problems Nerd Tools Preclear Disks Statistics unRAID Server OS Dockers that I have: mariadb-cloud nextcloud noip plexmediaserver transmission Quote Link to comment
Squid Posted May 24, 2017 Share Posted May 24, 2017 If a parity check doesn't automatically start, then the shutdown was "clean" Look at your UPS settings and/or power mains Quote Link to comment
phbigred Posted May 25, 2017 Share Posted May 25, 2017 Check your logs too while running. See if there are any reoccurring pop ups while running. Also for grins pin your CPU for plex in case that might be causing issues. Edit Docker for plex and under Advanced radio toggle look for extra parameters and add something like this... Extra Parameters: --log-opt max-size=50m --log-opt max-file=1 --cpuset-cpus=0,1,2,3 These settings keep the log for the docker in check and assign certain processors to isolate Plex. In my case with a hexacore with SMT I'm assigning cores 0-3 out of 12 total. Helps contain the dockers so they won't eat up all resources. Can be done for all your dockers if you like. If you have more than a quad core proc, maybe don't use 0,1 as Unraid likes the first couple for itself. Also if using the plex released docker make sure if you are tight on RAM to not set transcode to /tmp as that uses RAM and can cause issues if you don't have a lot of overhead. Just my 2 cents.

sevenz Posted May 25, 2017 Share Posted May 25, 2017 I changed to a much higher PSU. 450W, to 500W, now 750W Gold Seasonic. 12hours with no downtime, looking great. 20 hours ago, Squid said: If a parity check doesn't automatically start, then the shutdown was "clean" Look at your UPS settings and/or power mains I've got Unclean Shutdown detected. 13 hours ago, phbigred said: Edit Docker for plex and under Advanced radio toggle look for extra parameters and add something like this... Extra Parameters: --log-opt max-size=50m --log-opt max-file=1 --cpuset-cpus=0,1,2,3 Where can I put this parameter? I get docker Plex from official website and this is the settings.

phbigred Posted May 25, 2017 Share Posted May 25, 2017 (edited) Toggle the switch at the top right of the screen (Where it says basic view) Edited May 25, 2017 by phbigred Quote Link to comment

I guess it's really the PSU. I will try to RMA it. Anyway, got it! Thanks for the extra parameters Quote Link to comment
