But to dump a ufs fs and restore it to a ufs2 fs is not the same thing, nor is it the 'normal' application for dump/restore. Maybe this is quite a valid thing to do; I'd like to see an 'official' statement to that effect -- I find your argument in relation to this situation unconvincing. Sorry about that. But you seem to be convinced by your investigation that the problem is elsewhere so at least tentitively I will accept that it is valid thing to do even though I dismiss your argument. Malcolm
