zfs mirror recognizing disk failures

[Michael Boers]

Is there anything I can do to make a zfs mirror quicker to give up on  
a flaky disk?

I recently had a 100% zfs system crash when started to have some disk  
errors.  I had hoped that by having a mirror, the system would survive  
this type of error.  Instead it just hung.

Is this a type of error zfs can survive or do I need a hardware mirror  
to handle this type of problem?

Thanks,
