smartctl and contradictionary disk status.

[ferg22]

I am using TrueNAS-12.0-U8.1 core running on a HP microserver gen6or7 (n36l) with 16GB of RAM and four HGST HDN726060. I am trying to sort out arranging my disks to spin down when not in use. There are a number of issues the first of which is with smartctl itself. As can be seen the disk is a HGST Deskstar.

I have been playing with the following three commands
smartctl -i /dev/ada0 -n standby
smartctl -i /dev/ada0 -d sat -n standby
smartctl -i /dev/ada0 -d sat,auto -n standby

With the disk spinning I get the following.

Code:

        smartctl -i /dev/ada0 -n standby
                smartctl 7.2 2020-12-30 r5155 [FreeBSD 12.2-RELEASE-p14 amd64] (local build)

With the disk spinning why do I get the contradictory status reports, and why does "-d sat,auto" fail.

Thanks in advance

Further to the above, I realised I was confusing sata disks with the sat device type. But smartctl also fails with "-d ata" the only thing that works is "-d auto". What is special about "auto"? This may be related to raid controller in the microserver, but I am using AHCI mode .

However I discovered https://forums.freebsd.org/threads/...mmand-ioctl-inappropriate-ioctl-for-de.84536/ which suggests there may be an issue with smartctl version 7.2.

So how soon might it be before truenas adopts smartctl 7.3? Or is it sensible to install the latest BDS smartmontools myself?
