Yesterday I noticed that I got this error in the console
As soon as I noticed that I ran the following smart tests (in this order): Short, Conveyance and ended with a long test.
I checked the smart results after each test. No errors after both the short and conveyance tests.
But after the long test I got this smart result:
Since it says "Completed: read failure" I'm assuming that this isn't good. But I'm a bit confused since the Raw Read Error Rate still is at 0.
Is this an early indication of drive failure or could it be something else, like a bad cable or something?
I'm new to FreeNAS and I've never completely understood how to read the smart results, so I'm hoping you guys can help me out.
