GTP Posted June 26, 2020 Share Posted June 26, 2020 Hi everyone, I have a disk that is disabled right now, I had an unclean shut down for an unknown reason (I just came downstairs and saw the server rebooting) and when I restarted the array disk 15 was disabled and would not start. I tried restarting the array in maintenance mode and checking the disk but it doesn't seem to have done anything the disk still has a big red x next to it and is still disabled but now I have a green pop up that say 0 read errors found. Is the disk dead? Should I take the disk out and replace it and have it rebuild the disk. Before I did anything though I thought it would be best to consult with the experts in the forum as I am unfamiliar with the steps to take in this situation.. Thank you so very much!

itimpi Posted June 26, 2020 Share Posted June 26, 2020 The red ‘x’ does not necessarily mean a drive has failed - just that a write to it failed for some reason. If you attach your system’s diagnostic zip file (obtained via Tools -> Diagnostics) to your next post you will get more informed feedback. it a;ways takes manual action to clear the ‘disabled’ state. Details on this are covered in this section of the online documentation. 1 Quote Link to comment
GTP Posted June 26, 2020 Author Share Posted June 26, 2020 Thanks @itimpi I wanted to run both the short and extended smart tests before I posted my diagnostics. I have attached the zip file. I read through this wiki https://wiki.unraid.net/index.php/Troubleshooting#What_do_I_do_if_I_get_a_red_X_next_to_a_hard_disk.3F and I am ready to re-enable if that is what I should do but I wanted to make sure I am not doing anything wrong or in the wrong order before doing so. Thanks again! GTP tower-diagnostics-20200625-2129.zip Quote Link to comment
JorgeB Posted June 26, 2020 Share Posted June 26, 2020 Lots of UDMA_CRC errors, replace the SATA cable and rebuild on top, assuming the emulated disk shows the correct data. 1 Quote Link to comment

Thank you for looking at that. Just so I can re-iterate what you said you think I should replace the SATA cable and drive(this is the part I am confused about, as in failed drive chuck it) and then rebuild drive 15 from parity. I can do that, thank you for your assistance. Thank you! GTP Quote Link to comment

GTP Posted June 26, 2020 Author Share Posted June 26, 2020 (edited) Rebuilding now should be done inbetween 12 hours and 2 days I will close the issue then. Thank you for your help again @johnnie.black Best, GTP Edited June 26, 2020 by GTP Quote Link to comment
josto Posted February 28, 2023 Share Posted February 28, 2023 I have a Disk Error and I think it might be due to an unclean shutdown. So the parity-disk shows errors, but still it has green dot in front and the last parity check completed finding 0 errors. But if I click on "Disk Log Information" I get error messages. How should I fix this? Thank you very much for any help! P.S. I attach the log file tower-diagnostics-20230228-1749.zip Quote Link to comment
JorgeB Posted February 28, 2023 Share Posted February 28, 2023 Unclean shutdown should not cause disk errors, parity appears to be failing, run an extended SMART test since these errors can sometimes be intermittent. Quote Link to comment
josto Posted March 1, 2023 Share Posted March 1, 2023 That's good to know, thanks. I ran the extended SMART Test, it completed without errors. Still, there appeared the notification "Array health report (FAIL)". Isn't that contradictory, what am I missing here? I'll attach the result if you could help me understand it. Thanks tower-smart-20230228-1844.zip Quote Link to comment
JorgeB Posted March 1, 2023 Share Posted March 1, 2023 Test passed so disk is OK for now, keep monitoring. Quote Link to comment
josto Posted March 13, 2023 Share Posted March 13, 2023 Things got worse, the disk is now disabled. Does this means it is broken and I need to replace it? Quote Link to comment
josto Posted March 13, 2023 Share Posted March 13, 2023 Of course. Sorry I forgot. Here it goes, thanks so much! tower-diagnostics-20230313-1904.zip Quote Link to comment
JorgeB Posted March 13, 2023 Share Posted March 13, 2023 Parity was generating errors for many days, and they are logged as a disk problem, you forgot this part: On 3/1/2023 at 12:23 PM, JorgeB said: Test passed so disk is OK for now, keep monitoring. Based on its history it should be replaced. 1 Quote Link to comment
josto Posted March 13, 2023 Share Posted March 13, 2023 Crap.. I was away for a couple days, and just got the error messages on my Telegram. Well, I guess I'm gonna buy a new disk then. By the way, what should I have done differently? Could I have saved the disk? Quote Link to comment

josto Posted March 13, 2023 Share Posted March 13, 2023 Got it. Thanks a lot for your help! 1 Quote Link to comment
