If no other writes occurred during the capacity upgrade then I'd suspect it would be possible. The transaction numbers would still vary across the drives and the pool information would be inconsistent but I suspect a recent version of ZFS could manage to recover. It might be possible to test this by creating a small, file-backed RAIDZn zpool, simulating a capacity upgrade, exporting that pool and trying to import the original zpool from the detached files. -- Peter Jeremy
