Thank a lot,

I will certainly report the result after resilver finished.

It's not production. We are only testing the fault tolerance before
entering it to production use.

PS: Thank you very much, it feels like Sun Microsystem is alive again and
you applied to the most qualified support ever.

Thank you.

So you're running LTS, AND it is up to date as of today.  This helps me
understand some things. IF this was fixed already in later releases (under
a different bug id), we likely deemed it too big/intrusive to backport to
an LTS release, or we overlooked its importance.

As for the busy filesystem, I wonder if it'll behave better after your
resilver finishes?  Otherwise, I'm not immediately sure what to tell you.

And one last thing... I'm travelling back home today, so I'll be
unavailable in a couple of hours.

Dan
