Not so fast! :-) If you promote this new clone, the current state / branch of your filesystem becomes a clone instead, dependent on the snapshot. Then if you try to destroy the snapshot, you'll fail, because it has a dependent clone (your current fs!!!). If you continue without realising the implications, and so try the 'destroy' again with '-R', there goes the neighbourhood! I did this once, and was only saved by the fact that my cwd was in my current filesystem, so couldn't be unmounted, and therefore couldn't be removed! Phew!! Nice to learn something and only get singed eyebrows, instead of losing a leg! hth Andy _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
