Adding partition

[Markus Oestreicher]

Good Day,

There is free space at the end of my disk and I want to move
/usr/ports do a dedicated partition.

# disklabel /dev/ad10s1
# /dev/ad10s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
   a:  1024000        0    4.2BSD     2048 16384 64008
   b:  2252800 44032000      swap
   c: 368627427        0    unused        0     0   # "raw"
   d:  2048000  1024000    4.2BSD     2048 16384 28552
   e: 20480000  3072000    4.2BSD     2048 16384 28552
   f: 20480000 23552000    4.2BSD     2048 16384 28552

I want to add a g partition with 10 GByte to end.

When I enter "disklabel -e /dev/ad10s1" vi opens and I add
the following line to the end:

   g: 20480000 44032000    4.2BSD     2048 16384 28552

Upon saving I get an error that partitions "c" and "g" overlap.
As far as I have read this is on purpose. How can I avoid the
error message?

I tried it via sysinstall but didn't work either. When saving
the new disklabels I get "Unable to write data to disk ad10".
I assume that is because ad10 is currently mounted?

Thank you!

Markus
