Its hard to tell what caused the smart predictive failure message,
like a temp fluctuation. If ZFS noticed that a disk wasn't available
yet, then I would expect a message to that effect.
In any case, I think I would have a replacement disk available.
The important thing is that you continue to monitor your hardware
for failures.
We recommend using ZFS redundancy and alway have backups of your
data.
Thanks,

Hi Cindy,
Not very enlightening.
No previous errors for the disks.
I did replace one about a month earlier when it showed a rise in io errors, and
before it reached a level where fault management would have failed it.
The disk mentioned is not one of those that went FAULTED.
Also, no more smart error events since.
The ZFS failed on boot after a reboot command.
The scrub was eventually stopped at 75% due to the performance impact.
No errors were found up to that point.
One thing I see from the (attached) messages log is that the zfs error occurs
before all the disks have been logged as enumerated.
This is probably the first reboot since at least 8, and maybe 16 extra disks
were hot plugged and added to the pool.
The Hardware is a Supermicro 3U plus 2 x 4U SAS storage chassis.
The SAS controller has 16 disks on one SAS port, and 32 in the other.
