Hello,
I am a beginner on FreeNAS and after using my FreeNAS system I now seem to have a problem. This morning at 03:00 I got a system email that the scrub of the pool started, at 6:02 I got a system email with a critical alert:
Device: /dev/ada0, 1 Currently unreadable (pending) sectors
I quickly did some online research and found: https://dekoder.wordpress.com/2014/10/08/fixing-freenas-currently-unreadable-pending-sectors-error/ and other similar solutions.
But after running the long test I had this for results:

1 0 0 Not_testing

4 0 0 Not_testing
5 0 0 Not_testing
Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
For as far as I can understand there are no errors reported, no LBA_of_first_error so no way of knowing which sector is bad. I really need some help.
Can somebody explain me what to do next?
Forgive me if my englisch isn't 100% ok :) (I am from Holland)
