Shadey1 Posted July 12, 2023 Share Posted July 12, 2023 (edited) I need some help please! Parity ran Sunday or Monday night, and was fine 0 errors. I then replaced a small (and old 13y+ drive) Tuesday, let unraid rebuild and saw this when I checked in this morning. I had some loose cables when I first booted back up, reseated them all and added the drive to the array. That's a lot of errors!

Shadey1 Posted July 12, 2023 Author Share Posted July 12, 2023 That's me being dumb, I thought I had. Sorry about that! wintermute-diagnostics-20230712-0631.zip Quote Link to comment
JorgeB Posted July 12, 2023 Share Posted July 12, 2023 Parity appears to be failing, you can confirm by running an extended SMART test. Do you still have old disk4 intact? Quote Link to comment
Shadey1 Posted July 12, 2023 Author Share Posted July 12, 2023 Yeah it's sat here, it hadn't failed I just needed more space Quote Link to comment
Shadey1 Posted July 12, 2023 Author Share Posted July 12, 2023 Finished while I was at work. Quote Link to comment
JorgeB Posted July 13, 2023 Share Posted July 13, 2023 Note that the rebuilt disk will have some corruptions due to parity read errors, if the SMART test confirms the problem with parity do a new config with old dis4 and re-sync to new parity. Quote Link to comment
Shadey1 Posted July 13, 2023 Author Share Posted July 13, 2023 Cool, I'm running the long smart test on the parity drive now. I'll report back in about 12 hours I guess! Thank you Quote Link to comment

Shadey1 Posted July 14, 2023 Author Share Posted July 14, 2023 Thank you! So am I right in thinking then that: Step 1 is take out the replacement drive since parity failed. Step 2 replace the parity drive Step 3 New drive to expand space And thank you again for helping, I find I don't have to think about my server for so long that when I do I question all the basics again!

Solution JorgeB Posted July 14, 2023 Solution Share Posted July 14, 2023 You need to do a new config (Tools -> New config) with old disk4 and a new parity, once the new parity is synced you can replace disk4. Quote Link to comment
Shadey1 Posted July 14, 2023 Author Share Posted July 14, 2023 Ah thank you, that makes sense, I've ordered a drive and I'll get that running asap Typical that it dies the second I buy a new one. Quote Link to comment
Shadey1 Posted July 19, 2023 Author Share Posted July 19, 2023 Just wanted to say thanks again, just rebuilding parity but it looks like it's going well. Next thing on the pad is the reiserFS issues, but at least I have a while to sort that! 1 Quote Link to comment
