I recently upgraded from unRAID 6.19 to 6.20 and added a second Parity disk.  Now I periodically get status alerts "Array Health Status [FAIL]" .  The first alert was RED in color, all following alerts have been Orange (??).  The Array is online and appears to be functioning fine.  Any ideas? Diagnostic file attached.

Disk2 has read errors, although there are no pending sectors it looks like a disk problem, run an extended SMART test.

Thank you - Extended SMART test on disk2 completed without error.  I have attached updated diag log.  What's interesting (at least to me) is that disk2 used to have the SMART yellow warning triangle  due to 1 sector either pending reallocation or reallocated (I don't recall which message it was).  This 1 sector SMART status had been present for at least 6 months and was not triggering any alerts or warning popups.  During the second parity disk rebuild I did notice the multiple messages in the unRAID log about error reading a group of sectors.  After the second parity disk came online I noticed that disk2 SMART yellow warning triangle was gone. A green popup message also appeared stating (paraphrasing)  disk2 SMART status has returned to normal.

 

I'm not concerned if the array[FAIL] message is being caused by unRAID parsing the log and seeing the previous read error entries. 

 

Any other ideas / suggestions?

 

Thanks,

-Jason

If you reboot it will reset the read errors and you won't get more array heath fail errors, since the disk passed the extended SMART test it should be good for now, keep monitoring it and if it has more issues in the near future replace it.

Thanks! Your guidance was spot on, I have restarted the server, no more array fail popup messages.
