You appear to be right - I see it now. I had not read closely enough, and had focused more on what I could change with the 'm' disklabel(8) command. It would be nice if this info were made explicit in the growfs(8) man page as well. I had already successfully rearranged some partitions using the method you propose, but unfortunately the amount of data in /project is slightly too big to be easily shifted into my remaining free space. I'll try to compress it or temporarily move the data off-system. Thanks for the clue-stick. --david
