modifying the root device's disklabel

Hello managers,

I need to expand the size of my root (advfs) filesystem on a 4.0e 8200
system. The root device, rz32, resides on a non-shared hsz50. I booted
from the installation 4.0e cdrom, chose the "unix shell" option, did a
./MAKEDEV rz32 and my device is seen by the system with its present
disklabel. I modified the disklabel to reflect the changes I want and when
I come to save it, it gives me the error "Partition 'a' is in use; Cannot
modify its size or location." I booted from cdrom, so that device should
definitely not be in use, so what is going on? I am only using partitions a
and b on this disk (root and swap only). As far as I know I should be able
to do this without losing any data on my disk, as long as I am increasing
and not decreasing the size of my 'a' partition. I didn't think I had to
zero out my disklabel, editing it then have to restore my data, but is that
what must be done?

Can anyone help out? I will summarize.

Thanks in advance and happy new millenium!

Kim
