Hi,
I was wondering what is the proper procedure for using fdisk to setup
slices on large disks/arrays? I seem to be getting an "ERROR" when
fdisk tries to adjust the partition to start on a head boundary and
end on a cylinder boundary.
Should I ignore the warning re: "partition does not end on a cylinder
boundary" and write the partition table? Or should I attempt to set
all the correct numbers by hand, since the automatic correction fails?
I've attached the warnings and errors I saw on fdisk.
