This may have been mentioned elsewhere and, if so, I apologize for
repeating.
Is it possible your difficulty here is with the Marvell driver and not,
strictly speaking, ZFS? The Solaris Marvell driver has had many, MANY
bug fixes and continues to this day to be supported by IDR patches and

We've had systems that used the sd drivers until we upgraded to newer, sun

You might check the hardware compatibility list at Sun's site.. It might list

I'm not sure, it's been a while since I've looked at it...

Heh, that's one thing I love about Linux & Solaris - the amount of info you can
find if you know what you're doing is scary. However, while that will work for
the Marvell SATA card I do have fitted in a server, it's not going to help for
the others - they are all items I'm researching for our n

D'oh. I'm far too used to downloading documentation online... when you come
from a windows background having driver manuals on your system is rather
unexpected :)
Thanks James.

Where to find information?Do some searching...
1st off, run through the drivers loaded via modinfo - look to see if anything
there is specific to your card.
prtconf -v | pg - again, looking for your controller card... once you find it
- look at the driver listed or tied to it, or failing t

Interesting, thanks Miles. Up to this week I've never heard that any of this
was tunable, but I'm more than happy to go in that direction if that's the way
to do it. :-)
Can anybody point me in the direction of where I find documentation for
tunables for the Marvell SATA driver, the LSI SAS dr
Hi,
Most of the time while waiting on a disk to fail is spent in disk drivers and
not ZFS itself. If you want to lower the timeouts than you can do so by
configuring different timeouts for sd. ssd or any other driver you are using.

Hi Richard,
Yes, I did miss that one, but could you remind me what exactly are the sd and
ssd drivers? I can find lots of details about configuring them, but no basic
documentation telling me what they are.
I'm also a little confused as to whether it would have helped our case. The

It's also very hard for the primary ZFS developers to satisfy everyone
I'm sure this has been discussed in the past. But its very hard to
understand, or even patch incredibly advanced software such as ZFS
without a deep understanding of the internals.
It will take quite a while before anyone can start understanding a
file system which was developed behind closed door

what`s your disk controller?
