Installed unraid for the first time and as per the manual waited for the array to complete its initial parity check (19hours). After it completed the array reported errors on one of the disks.

 

 

The SMART however seems to be ok (pic attached).

 

Using the forum search, the advice generally seems to be check the power and sata connections, which I now have. Should I now re-run the parity check before formatting the drives and adding data? Should I be more concerned about these errors?

It's a known issue with v6.11.2, update to v6.11.3 and re-format the disks.

Thanks Jorge. Updated then rebooted and the error was cleared.

 

 

I didn't notice the errors on disk2 before, those are unrelated to the format problem, you should run an extended SMART test on that disk.

So I ran the Extended SMART test and receieved the below results. The only attribute that updated was Multi zone error rate with a value of 311 but if I'm reading it correctly the test stopped after just 20% completion?

 

 

 

The drive is out of warranty. Any advice on whether it's still safe to use in an unraid array or how to test it further?

You should NOT continue to use any drive that is unable to complete the extended SMART test.

Like mentioned the disk should be replaced if the SMART test fails.
