If so, you're probably hosed. To add space onto a partition, the available space needs to be immediately after it. Unless Partition Magic can move things around to put the free space immediately after the /usr partition, you're not going to be able to growfs it. Last time I used PM, it didn't have much understanding of BSD filesystems, that may have changed, but I don't know. > You said: > > _Assuming_ your Windows partition is the last partition on the > HDD, and the > > /usr partition is second to last, the following will work: > > > > 1) BACK UP any important data ... this procedure is easy to > screw up! > > 2) Use PM or something similar to remove the Win partition and > expenad the > > BSD partition to take up the space used by Win.

I didn't know that partition was so small. > I will do some hunting for info on single user mode and growfs > before proceeding.

You can't growfs a mounted partition (unless something has changed?) If you can manage to get the /usr partition unmounted in multiuser mode, that will work as well. > Thanks again for such really good help. > Graham/ > > > ----- Original Message ----- > From: "Bill Moran" <wmoran@potentialtech.com> > To: "Graham North" <graham.north@telus.net> > Cc: <freebsd-questions@freebsd.org> > Sent: Saturday, July 10, 2004 2:50 PM > Subject: Re: resizing my slices/partitions - was pruning the Ports > tree > > > > [Please wrap your lines around 72 chars or so ... see > > http://www.lemis.com/questions.html ] > > > > "Graham North" <graham.north@telus.net> wrote: > > > Hello all: > > > > > > I would like to expand my FreeBSD partion on the hard drive > of which it only > > > has 60%. > > > The rest of the HD holds an old installation of Win98. > > > > > > When I first installed FBSD 4.8 I used Partition Magic to > carve off 1.2G of a > > > 2.0G HD and give me dual boot capability so as to retain the > Win98.
