Suppose one has a ZFS/zpool mirror.
One of the duplicates is detached from the mirror.
At a later time, it's re-attached to the same mirror, causing
re-silvering. Assume much of the content in the pool hasn't
changed between the detach and attach times.
Will re-silvering do some sort of incremental update, or always
copy everything?
Is the answer different for offline/online?
Just curious. Thanks,
-WBE
