Have you considered ZFS? Ive used ZFS in the past, but without going off topic, i have found it wanting. And at this stage, i dont have a large number of disks (or tape) to shift the data off and reformat. > At this point you can't put a bsdlabel on, as your filesystem probably > encroaches on the area the label would need anyways.

Perhaps that is the problem you are running in to. Could well be. The man page didnt provide me with the insights i needed, hence consulting this list. The error message that growfs gives isnt as helpful as it could be so im about to dive through the source and see what causes this message to appear. Is there a way to free space in that cylinder group? Dean
