Hi Chris,
the problem that I’d like to highlight is related to the Pool configuration:
even if it’s a mirrored pool, when I disk failed, the whole pool became unavailable. How is that possible?
Shouldn’t mirror configuration prevent this from happening?
It took a while, the end of the resilvering process if I remember well, until the pool became available again (even if in the DEGRADED mode)

Hi , thanks for the bug report. It looks like one of the pools is in a degraded state. In a degraded mirror corruption will be detectable but not repairable.

Thank you .
I have moved this ticket into our queue to review.
An engineering representative will update with any further questions or details in the near future.
