[OpenIndiana-discuss] Diagnosis help needed

[Mike La Spina]

I have observed the same SATA hard disk error wait behavior over many
operating systems. It's a SATA hardware issue. I have even observed it
on expensive high end storage servers. (HP, IBM, etc.) The SATA disk or
subsystem is trying to correct/recover errors, it should not and just
return the fault back to the caller (ZFS in this case). It can handle
the issue much more diplomatically and will correct the data fault
immediately. Don't blame ZFS, it is well designed, SATA on the other
hand is trying hard to do a bad thing.

I did a hard reset and moved the drive to another channel.

The fault followed the drive so I'm certain it is the drive, as people
have said.

The thing that bugs me is that this ZFS fault locked up the OS - and
that's a real concern.

I think I'm going to need to have a hard think about my options and
possibly leave OI for FreeNAS, Nexenta or Schillix.
