I gave caffeinate a try, and set my system sleep time to a more reasonable timeout [30 minutes], but since smartctl isn't an interactive process [a tsr?], the system never stays awake long enough to finish a whole test. I even added the -m option to prevent the disk from idle sleeping but that didn't help.
I wonder why Apple doesn't want to allow the selective test range...? -Ubence On Tue, Jun 26, 2018 at 9:31 PM Ryan Schmidt <[email protected]> wrote: > > On Jun 26, 2018, at 07:32, Ubence Quevedo wrote: > > > Ubences-MacBook-Pro:ata uquevedo$ smartctl -t long /dev/disk2 > > smartctl 6.6 2017-11-05 r4594 [Darwin 17.6.0 x86_64] (local build) > > Copyright (C) 2002-17, Bruce Allen, Christian Franke, > www.smartmontools.org > > > > === START OF OFFLINE IMMEDIATE AND SELF-TEST SECTION === > > Sending command: "Execute SMART Extended self-test routine immediately > in off-line mode". > > Drive command "Execute SMART Extended self-test routine immediately in > off-line mode" successful. > > Testing has begun. > > Please wait 206 minutes for test to complete. > > Test will complete after Tue Jun 26 08:52:02 2018 > > > > Use smartctl -X to abort test. > > > > There’s no way that will complete under my system’s sleep schedule > [three hour timeout for sleep] which isn’t ideal anyways. > > So tell the system not to sleep while the test is running. > > caffeinate -i smartctl -t long /dev/disk2 > > For more info: > > man caffeinate > >
