Indeed, even in snv_117 the zpool man page says that. But the
console/dmesg message was also quite clear, so go figure whom
to trust (or fear) more ;)
The FMA message is consistent with the man page.

The reason for disabled this in the first place was to fix bad NFS write

I've also tried setting the

So maybe a next step is to run zilstat, arcstat, iostat -xe?? (I forget what
people like to use for these params), zpool iostat -v in 4 term windows while
running the same test and try to see what is spiking when that high load
period occurs.
Not sure if there is a better version than this:
Here is a total guess - but what if it has to do with zfs processing running
on one CPU having to talk to the memory owned by a different CPU? I don't
know if many people are running fully populated boxes like you are, so maybe
it is something people are not seeing due to not having huge

I am seeing some spotty performance with my new Mangy Cours CPU...
It is like they are asking for it. I think they be better off doing something
like Intel core arch names using city names Santa Rosa, etc.

Sorry for the long post but I know trying to decide on hardware often want to

I believe it goes a something like this -

I would get a new 1.5 TB and make sure it has the new firmware and replace
c6t3d0 right away - even if someone here comes up with a magic solution, you
don't want to wait for another drive to fail.

zraid of these 8 Raid Groups. ~ 14TB usable.
I did read in a FAQ that doing double redundancy is not recommended
since parity would have to be calculated twice.
