drventure31 Posted January 17, 2020 Share Posted January 17, 2020 (edited) I keep running into issues with Unraid 6.8.0 and now 6.8.1 releases which ultimately causes me to rollback to a previous build. What im seeing in the syslog are nginx errors over and over and over. Once I see one error, unraid starts to become extremely unstable to the point of web gui becoming unresponsive and then the entire system goes unresponsive to the point where ssh into the machine isnt even possible I've seen a few other posts with others having similar issues but no solution has been discovered. Does anyone have any idea where i can even start to dig into the root cause? Error that i see multiple times in syslog: Jan 17 10:26:47 NEXUS nginx: 2020/01/17 10:26:47 [error] 10374#10374: *17 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 192.168.1.104, server: , request: "POST /webGui/include/DashUpdate.php HTTP/2.0", upstream: "fastcgi://unix:/var/run/php5-fpm.sock", host: "_________.unraid.net", referrer: "https://_______.unraid.net/Dashboard" nginx.conf attached Edited January 17, 2020 by drventure31 Quote Link to comment
bonienl Posted January 17, 2020 Share Posted January 17, 2020 Start your server in safe mode and retest. Quote Link to comment
drventure31 Posted January 17, 2020 Author Share Posted January 17, 2020 Changed to safe mode via main > boot device > syslinux config and selected unRAID OS Safe Mode (no plugins, no GUI). Rebooted the system and then it ended up hanging so had to hard shutdown. On boot (with array off) i see no nginx erros SWEET! However, syslog does show some other errors. Most peculuar is the one regarding a floppy and kernel bug related to drivers. Jan 17 12:28:13 NEXUS kernel: print_req_error: I/O error, dev fd0, sector 0 Jan 17 12:28:13 NEXUS kernel: floppy: error 10 while reading block 0 Jan 17 12:28:16 NEXUS kernel: ------------[ cut here ]------------ Jan 17 12:28:16 NEXUS kernel: kernel BUG at drivers/ata/sata_mv.c:2118!

drventure31 Posted January 17, 2020 Author Share Posted January 17, 2020 Also note, when trying to start the array in safemode, it hangs and does not start. seems unraid went unresponsive yet again... Last command in syslog is: Jan 17 12:31:24 NEXUS emhttpd: req (2): startState=STOPPED&file=&csrf_token=****************&cmdStart=Start Quote Link to comment

These are likely Supermicro SAT2-MV8 controllers, they have known issues with recent devices, both HDD e SSDs, driver not likely to be maintained any longer, best bet if it's not working correctly would be to replace them with an LSI HBA.

drventure31 Posted January 17, 2020 Author Share Posted January 17, 2020 Sounds good, Ill jump out there and flip those off in bios. Could the controllers be triggering issues with nginx? Since the controllers i have right now are old and unsupported in 6.8.x it could be possible that the files nginx process is digging for are just unavailable? Just spitballing here.. side note: Just got the nginx error while waiting for the array to try to start (it never started fyi). Jan 17 12:37:21 NEXUS nginx: 2020/01/17 12:37:21 [error] 2205#2205: *842 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 192.168.1.104, server: , request: "POST /update.htm HTTP/2.0", upstream: "http://unix:/var/run/emhttpd.socket/update.htm", host: "_____.unraid.net", referrer: "https://_____.unraid.net/Main" I've previously looked at new controllers but decided to wait to upgrade... guess the time has come Anyone have any recommendations? Otherwise, im just going to research through the list posted here: https://wiki.unraid.net/Hardware_Compatibility Quote Link to comment

drventure31 Posted January 17, 2020 Author Share Posted January 17, 2020 Any other ideas on things to check for the nginx errors that seem to be crippling unraid 6.8.x? I/O error 'floppy' FIX: try and disable in BIOS kernel BUG at drivers/ata/sata_mv.c:2118! FIX: Drivers for (Marvell MV88SX6081 8port SATA II PCI-X) likely not being maintained, recommend upgrading controllers if on Unraid 6.8.x nginx error - upstream timed out while reading response header (see above for full error) . Workaround: roll back to non 6.8.x versions of unraid. Quote Link to comment
bonienl Posted January 17, 2020 Share Posted January 17, 2020 Are you saying the problem did not exist in earlier versions of Unraid? To me it seems you have a hardware related issue, which impacts the behavior of the box. Quote Link to comment
drventure31 Posted January 17, 2020 Author Share Posted January 17, 2020 Correct. I just rolled back to latest 6.7.x version and having no issues at all. The issue specific to the hangs with nginx errors in syslog is limited to 6.8.0 and 6.8.1. if there are logs I should checkout I’m totally open to upgrading again and getting more data as needed.

Cpt. Chaz Posted January 19, 2020 Share Posted January 19, 2020 is it possible this nginx error could be related to the same one im experiencing? erros look different, but nginx seems to be a common denominator. i havent found a solution yet either. could try rolling back to 6.7 and see... but i never had any problems before 6.8 either, and no other major changes since the upgrade aside from wireguard install / use.
