I am still having issues with this. A few years ago I did asked about
disklabel not showing up properly and I was told not to worry about, but
now I need to increase the size of some partitions with unallocated
space on my drive like Nick recommended to do. (:>
But my disklabel don't look right to me, however all works fine, so how
can I make sure that after a reboot if I just do a disklabel wd0, it
would be fine and look OK. I am a bit nervous before making changes to
the disklabel obviously.
So, after a reboot I get:
# disklabel wd0
# /dev/rwd0c:

=====================================
Now, I do:
# disklabel -E wd0
This platform requires that partition offsets/sizes be on cylinder
boundaries.
Partition offsets/sizes will be rounded to the nearest cylinder
automatically.

=================================
All look fine.
But a reboot comes back again with the warning on top of this email.
So, I take that as all been fine and good, but isn't it a way to really
not see this warning.
I don't play with disklabel very often, but when I do and see this, it
always make me pause first before I do anything stupid.
Any thoughts on this.
I guess I most likely over react, but I like to be safe.
Plus I do write the disklabel ( I think I do anyway as above), so why
doesn't it see it?
Thanks
Daniel
