Kjetil Posted June 28, 2023 Share Posted June 28, 2023 (edited) Hello everyone Logged onto unraid today and saw an error message, parity disabled. So I took a diagnostic and shut down unraid. I add the diagnostics here. Disregard the error messages for the UPS, its disconnected but I have not updated unraid. What to do now? Start up the raid again ? Or boot in safety mode? I am not tech savy so hoping someone can help with fairly detailed descriptions.... I did a parity check a few weeks ago, showed no errors. And have not had disc error messages either. Very thankful for any help. Kind regards, Kjetil federalreserve-diagnostics-20230628-1043.zip Edited June 28, 2023 by Kjetil Quote Link to comment
JorgeB Posted June 29, 2023 Share Posted June 29, 2023 Both disks look healthy and dropped at the same time, so most likely a power/connection issue, do they share something in common, like a splitter? Quote Link to comment
Kjetil Posted June 29, 2023 Author Share Posted June 29, 2023 Not sure actually. Should I restart Unraid and check if all is ok ? Quote Link to comment
JorgeB Posted June 29, 2023 Share Posted June 29, 2023 I would at least check/replace cables and then re-sync parity Quote Link to comment
Kjetil Posted June 29, 2023 Author Share Posted June 29, 2023 Don't have any cables, so would need to order in. But I can do it. Do I boot as normal, and start the unraid? How do I do the re-sync? Quote Link to comment
Solution JorgeB Posted June 29, 2023 Solution Share Posted June 29, 2023 https://docs.unraid.net/unraid-os/manual/storage-management#rebuilding-a-drive-onto-itself You can do both at the same time. Quote Link to comment
Kjetil Posted July 1, 2023 Author Share Posted July 1, 2023 So I remove the two parity discs by choosing "no device", then start and stop the array, then reassign the two discs, and start the array again in maintenance mode (choosing sync to rebuild) ? Quote Link to comment
JorgeB Posted July 1, 2023 Share Posted July 1, 2023 Yes, but no need to do it maintenance mode, or the array will not be available during the sync. Quote Link to comment
Kjetil Posted July 7, 2023 Author Share Posted July 7, 2023 Rebuilt parity, so now it's working. Thanks for your help JorgeB 😊 1 Quote Link to comment
Kjetil Posted July 19, 2023 Author Share Posted July 19, 2023 After using the server a few weeks, it suddenly fell out of the network. It was still on but not responding, also there was no picture when connecting a screen directly to the server vga output. Had to do a forced power off. And power on again. Now it's working again and online. I added the diagnostics here, are you able to see anything from the diagnostics? Error message etc ? federalreserve-diagnostics-20230719-2055.zip Quote Link to comment
Kjetil Posted July 19, 2023 Author Share Posted July 19, 2023 And now it happened for a 2nd time in just 1 hour... must be some hardware fault... mainboard? Quote Link to comment
Kjetil Posted July 19, 2023 Author Share Posted July 19, 2023 Not sure how to find the fault... Quote Link to comment
JorgeB Posted July 20, 2023 Share Posted July 20, 2023 That looks more like a hardware issue but you can enable the syslog server and post that after a crash. Quote Link to comment
