I'm trying to run a disk test with smartctl -t long on FreeNAS.

But the test immediately aborts with Aborted by host.

From what I've read, this is because the system is using the drive, so it cannot continue to test.

How can I allow the test to finish? Unmount the volume? Use captive mode?

The answer was patience ... the following morning, all the SMART tests completed. Apparently they get scheduled and eventually do complete, perhaps when disk activity is down.
