According to SMARTReporter, they claim there is a bug that prevents them from working:

> i believe you are using OpenZFS. we have added support for Zevo ZFS. there is a known limitation in OpenZFS that affects us and other products ( https://openzfsonosx.org/forum/viewtopic.php?f=26&t=1755 ). i believe if they fix it, it should work.

 SMARTReporter not showing MacZFS Drives

Marc Mosko <incerto...@gmail.com> Jul 20 09:14AM -0700  

hello,
 
New mac ifs user here! I have 3x Seagate ST3000DM001 in a RaidZ1 on a Mac
Pro (mid 2012), all in internal drive slots.
 
SMARTReporter sees my boot drive (flash) and an external USB drive and "1
disks(s) not SMART capable" which I assume is the zfs drive (not the dvd).
 
Is there anything special that needs to be done to a zfs pool for SMART
monitoring?
 
I created the pool following the quicks start guide, creating a ZFS
partition then adding those partitions to a raidz.
 
Also, what are the "read / write / cksum" columns from "zpool status"? The
man page does not describe them.
 
Thank you

As far as I know, a choice of file system (or storage system) should not
affect whether the operating system can work with S.M.A.R.T.-capable
hardware.
 
Whilst I'm not very familiar with SMARTReporter, I'm surprised that it
appears to not find S.M.A.R.T. capability for any of the three internal
drives.
 
That said, you might find the following of interest:
 
kasbert <https://github.com/kasbert>/*OS-X-SAT-SMART-Driver
<https://github.com/kasbert/OS-X-SAT-SMART-Driver>*
 
– try the 0.9 release, restart the Mac then see whether Disk Utility and/or
SMARTReporter treat the three drives as supporting S.M.A.R.T..

Software does not always work with other software and/or hardware, this is neither a limitation or a feature, just reality of needs. 

If enough people use SmartReporter or similar tools for whatever reasons, someone will probably take the time to update the OpenZFS code. 

You can open a ticket if you can provide more detail and eventually I'm sure the issue will be resolved.
