Hi there,
WebUI shows an alert for /dev/ada0: Device: /dev/ada0, 3 Currently unreadable (pending) sectors.
I ran a long / extended SMART test for that disk. The result showed no errors.
After the test run i scrubed the whole pool -> no known data errors, pool is ONLINE.
A couple of hours later i ran another SMART long test. This is the result:
Still no errors ("Completed without error").
So do i need to replace that disk with a new one? This hdd is part of a mirror, not a raid(z).
Thanks for our help.
