naught Posted January 24, 2021 Share Posted January 24, 2021 Yesterday I was transferring some files from an external hdd (in a usb 3.0 dock) to the array. I mounted the ext hdd via the unassigned devices plug-in. I was performing a verbose rsync, and after about half the directory was transferred I/O errors popped up. The external drive had become unmounted. I remounted in unassigned devices, and restarted the rsync. Eventually I noticed the same errors again, but this time I could not remount the hdd. Unlike the first involuntary unmount, I could no longer see unassigned devices settings in the web ui. Eventually the entire web ui stopped working, and gave me 500 errors. I could ssh to the server, and all my docker containers were still working. I tried a few things- restarting nginx, etc, per suggestions in the forum, but nothing brought the web ui back. FYI: I tried two web browsers from my laptop (brave and firefox.) Neither worked, nor did accessing from a tablet and phone (chrome and brave.) So finally I ran "diagnostics," and rebooted from the cli #reboot After restart, I still get 500 errors attempting to access the web ui. I can access via ssh, and the docker containers all work. (Though SMB does not for some reason.) Here is what I expect is the significant portion of the diagnostics syslog: 24 07:30:25 azathoth nginx: 2021/01/24 07:30:25 [error] 6855#6855: *13573 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 192.168.1.109, server: , request: "GET /Main HTTP/1.1", subrequest: "/auth_request.php", upstream: "fastcgi://unix:/var/run/php5-fpm.sock", host: "192.168.1.181" Jan 24 07:30:25 azathoth nginx: 2021/01/24 07:30:25 [error] 6855#6855: *13573 auth request unexpected status: 504 while sending to client, client: 192.168.1.109, server: , request: "GET /Main HTTP/1.1", host: "192.168.1.181" I deleated /boot/config/ssl per some suggestion in this forum, and rebooted again, and I still have the same problem. Any suggestions? I am medium-level tech savvy fwiw. azathoth-diagnostics-20210124-0757.zip Quote Link to comment
JorgeB Posted January 25, 2021 Share Posted January 25, 2021 Try booting in safe mode and post diags after that if it still doesn't work. Quote Link to comment
naught Posted January 25, 2021 Author Share Posted January 25, 2021 How do I boot in safe mode from the command line? Quote Link to comment
JorgeB Posted January 25, 2021 Share Posted January 25, 2021 Edit syslinux.cfg on the flash drive and move "menu default" form normal to safe mode. Quote Link to comment
JorgeB Posted January 25, 2021 Share Posted January 25, 2021 No, move it to the safe mode entry: Quote Link to comment

naught Posted January 25, 2021 Author Share Posted January 25, 2021 I'll try the non GUI mode next if GUI safe mode gets me nowhere... Thanks Quote Link to comment
naught Posted January 25, 2021 Author Share Posted January 25, 2021 Here's the diagnostics file from GUI safe mode. Let me know if regular old safe mode is required. I see no GUI, web or hdmi fwiw. azathoth-diagnostics-20210125-0559.zip Quote Link to comment
JorgeB Posted January 25, 2021 Share Posted January 25, 2021 Those diagas are not after booting in safe mode, probably the previous ones. Quote Link to comment
naught Posted January 25, 2021 Author Share Posted January 25, 2021 I deleted the old archive before running diagnostics, the one I posted was the only diagnostics archive present. I'll reboot in non-GUI safe mode and give it another shot. Thanks for your help and patience, Jorge. Quote Link to comment
naught Posted January 25, 2021 Author Share Posted January 25, 2021 reboot kicked my out of the terminal, but didn't reboot the system... root@azathoth:~# uptime -s 2021-01-23 10:26:07 Gonna try shutdown instead of reboot. wish me luck Quote Link to comment
naught Posted January 25, 2021 Author Share Posted January 25, 2021 I shutdown dockerd, unmounted all the disks, and reboot and shutdown still do nothing other than boot me from a terminal. I'm going to pull power and rebuild the usb drive. This is taking too much time. Quote Link to comment
naught Posted January 25, 2021 Author Share Posted January 25, 2021 (edited) Hard reboot gave me access to web ui. Considering this solved, will start new thread of I encounter unsurmountable problems. Thanks Jorge. azathoth-diagnostics-20210125-1043.zip Edited January 25, 2021 by naught 1 Quote Link to comment
