Well, as it says, your c partition doesn't start at 0, so it also can't cover the whole unit: # size offset fstype [fsize bsize bps/cpg] c: 78156162 63 unused 0 0 # (Cyl. 0*-4864*) What part of that don't you understand? > The disk was formatted by the FreeBSD install procedure. If you haven't changed anything here, it would be interesting to know in more detail just what you did. To judge by the surprising number of partitions, you didn't take the defaults. > The system is an older Digital PC (3500) PII 333 Mhz. > The disk is a 40 GB IDE drive (WD) > > BTW, I'm looking for a safe way to 'grow' my rootfs, I've looked > arround before, but I'm still not clear on the right procedure for > it. Take a look at growfs(8). To do it right, you need space directly behind the root file system. Even Vinum won't help here. You could move the swap space elsewhere, for example. > I'm considering reinstalling the system with 5.2, reformatting the > disk, There's seldom a reason either to reinstall or to reformat.

You can clear the error by running disklabel -e /dev/ad0s1a in single user mode, and changing the length and offset of partition c (offset 0, add 63 to the size).
