Checking whether some previous transactions are good. ( -Fn and then -F). There are also extra options made for debugging: 1. -X - xtreem rewind, tries transactions scrubbing each next one. 2. -T txg - specify a starting txg for import. Might be particulary useful if some previous transactions are not only damaged beyond repair but also make system dump core. Once in my life I had a problem with a pool that I ought to use -T - the controller was buggy and last few transactions were damaged badly. -- Sphinx of black quartz judge my vow.
