It is never good when a system panics, so that is not good.
But i can not help you with that.
Be aware that the spares in FreeBSD are cold, and human intervention is
needed to replace a drive.
I think a lot of people assume that the spare drive is automaticly
beeing replaced when a disk dies.
This is not the case.
I think that the zpool command should opt a warning when adding a spare
to the pool that it is not hot.
zpool should not accept the spare without any warning to the user that
it will not automaticly replace a dead drive.
regards,
Johan
