In contravention to all advice, I built my home backup server using whatever hard drives were available at the time. As a result I have a completely heterogeneous ZFS system as shown below.
I now have some spare money to upgrade the system, I am wondering how to determine which disks are the slowest performers and therefore where best to spend my meagre resources.
Everything I can find about ZFS reports statistics at the mirror level. I know my mirrors have some fast disks and some slow ones. Short of pulling each one and plugging it into a Linux system and running "hdparm -tT", is there any Solaris 11 command which will tell me the individual performance of each drive?
[Background - I started out as a C programmer and sysadmin on SunOS 4.1 20 years ago; now freshly back with Solaris after a 10 year experiment with Linux, and only because of the data security which ZFS offers.]
