Hi, sorry for not completely digesting your original post.

I would say it is definitely very odd that writes are a problem.  Sounds =
like it might be a hardware problem.  Is it possible to export the pool, =
remove the ZIL and re-import it?  I myself would be pretty nervous =
trying that, but it would help isolate the problem?  If you can risk it.
