In the absence of such a tool from an official source, is there a future plan/intention for providing such a thing within the scope of this project? I know that ZFS is supposedly designed so that it is always consistently recoverable, but I know of several cases at work where this wasn't the case after a crash, using pure stable Solaris.
Would such a tool be needed? I've always thought that scrub provides all of the features of fsck but is also able to work online. Is this not the case?
