I just got an alert about a SMART error during a long selftest on one of the WD-REDs in my FreeNAS mini. The SMART status looks like below. Should I run a scrub so zfs can fix the file(s) which use the sectors where the error(s) were encountered?

Edit: pool status and all datasets are healthy.
Thanks,
Saurav.
