Do we know exactly what kind of corruption happen to your pool? If
you see it twice in a row, it might suggest a software bug that should
be investigated.
Oh I did spot one interesting bug... though it is benign...
Check out the following (note the difference between 'zpool status' and
'zpool status -v'):

status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
