rowid_alex Posted October 6, 2017 Share Posted October 6, 2017 Hello, I am new to unRAID. Yesterday I noticed that the parity check is finished with 13 errors (the previous one 3~5 days before was finished w/o error). All disks are green in my array. I checked SMART data in all disks for 5, 196. 197, 198, and 199 and all healthy. Should I be worry about the parity check report or not? Attached is the diagnostic file. Thanks.

Thanks for the reply. That's due to a hang situation of unRAID after I started up a Win10 VM. I had to hardly reboot the tower. I am in a pre-release version so it might be not stable as the stable version. Will try to avoid this in the future. Link to comment
rowid_alex Posted October 23, 2017 Author Share Posted October 23, 2017 Hello, Today I did parity check again and still found 51 errors by the end. Since last parity check I don't have any unsafe shutdown. SMART data are all green. Should I worry about this or this is somehow normal? Diagnostics info attached. Thanks.

Thanks for the quick reply. However I am a bit lost that why I have to run memtest? BTW, in the boot menu of unRAID I have run memtest before, it may take about 40mins and over without any error. How could I let it run for 24 hours? Best Regards, Alex Link to comment

To see if there are any memory errors, though memtest doesn't always find them. 1 minute ago, rowid_alex said: it may take about 40mins and over without any error Not enough, even 24h may not be enough.

rowid_alex Posted October 23, 2017 Author Share Posted October 23, 2017 ok. thanks. I will double check the memory to see if any finding. Link to comment
rowid_alex Posted November 6, 2017 Author Share Posted November 6, 2017 Hello, I ran memtest for more than 35 hours and got no error a couple of days ago. Today I re-run the parity check still found 40 errors. Any other clue? BTW, I am thinking if still needed to have parity drive if I always got errors? If now I have a drive got failed, is it possible to recover the data by the parity drive? Best Regards, Alex Link to comment

Unfortunately no errors on memtest doesn't necessarily means there's no problem, only the opposite is true. 17 minutes ago, rowid_alex said: If now I have a drive got failed, is it possible to recover the data by the parity drive? You'd still be able to recover but it would probably have some corrupt files. 19 minutes ago, rowid_alex said: Any other clue? You'll need to start ruling things out, if you have more than a Dimm, try with just one at a time, or use a different board if available Link to comment
rowid_alex Posted November 7, 2017 Author Share Posted November 7, 2017 ok. I think I will stop here. A couple of errors sound still okay for me. As seen the NPT issue has been resolved on Ryzen build, next year maybe try AMD platform. Thanks a lot anyway! Link to comment
