You can try importing it with more recent ZFS version, I don't recall which exactly but some time ago there was new option -F added which resulted in trying more then last transaction on importing pool. You will need recent SystemRescueCD or OpenSolaris. Also you can try this script but be warned - it does destroy data. You will need to save first megabyte and last two megabytes from each pool device just in case. After that you can use this script to lookup last transactions and drop some of them. -- Sphinx of black quartz judge my vow. --------------020502010204060707030301 Content-Type: text/plain;
