Hi,
I´m sending this email to you because you are listed as maintainer of
the 'smartmontools' port.
I´ve been using smart daemon for long time but I´ve never been able to
use 'daily_status_smart_devices="auto"' in '/etc/periodic.conf' because
there are USB drives attached and smartctl can´t handle them, at least
not by default:
# camcontrol devlist
<ATA ST3000DM001-1CH1 CC24> at scbus0 target 0 lun 0 (da0,pass0)
<ATA ST3000DM001-1CH1 CC24> at scbus0 target 1 lun 0 (da1,pass1)
<ATA ST3000DM001-1CH1 CC24> at scbus0 target 2 lun 0 (da2,pass2)
<ATA ST3000DM001-1CH1 CC24> at scbus0 target 3 lun 0 (da3,pass3)
<ATA WDC WD30EFRX-68E 0A80> at scbus0 target 5 lun 0 (pass4,da4)
<Kingston DT Micro 1.00> at scbus6 target 0 lun 0 (da5,pass5)
<Kingston DT Micro 1.00> at scbus7 target 0 lun 0 (da6,pass6)
# smartctl -H /dev/da5; echo $?
smartctl 6.2 2014-02-18 r3874 [FreeBSD 9.2-RELEASE amd64] (local build)

So I´ve been looking at '/usr/local/etc/periodic/daily/smart', thinking
about a "smart" way to sort that out:) So if the script was to loop
through the disks in "sysctl -n kern.disks | sed -E 's/[[:<:]](cd|
ar)[0-9]+//g'" and compare with 'camcontrol devlist' for known types of
hard drives like ATA, SAS and SCSI to determine if it´s a "real" hard
drive or not, that would fix the problem. It could also have support for
recognizing virtual qemu hard drives because they too show up in 'sysctl
-n kern.disks'. Who knows, maybe smartctl will support that as well in
the future:) And then I made a patch that does that.

If you like it, please consider using it for the port and I would
finally be able to just say "auto" without having any issues with my USB
drives any more. The patch is also included as an attachment.
TIA
