SMARTReporter not showing MacZFS Drives

[Marc Mosko]

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

big:~ mmosko$ zpool list

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/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..

Ok, thank you.  I just wanted to make sure it wasn't something known about zfs.  Digging deeper, I see the SMARTReporter log says:

Jul 20 14:31:53 big.parc.xerox.com SMARTReporter[552] <Error>: Error: mountedHarddisks volumeParms.vMDeviceID == NULL

Jul 20 14:31:53 big.parc.xerox.com SMARTReporter[552] <Error>: Error: mountedHarddisks volumeParms.vMDeviceID == NULL

Jul 20 14:31:53 big.parc.xerox.com SMARTReporter[552] <Error>: Error: mountedHarddisks volumeParms.vMDeviceID == NULL

Jul 20 14:31:53 big.parc.xerox.com SMARTReporter[552] <Info>: I/O-Error check: O.K. - No problems found on all 2 checked disk(s).

So I suspect there's something going on with it.  Disk Utility shows "SMART Status: Verified" for the 3 drives.  I've sent a support request to Core Code about it and will update this post once I find out.
