Thanks for the feedback, I seem to have made some mistakes in explaining
the situation. I am not really a newbie I know most of the fdisk and
parted tools almost out of my head.
The question is more about resizing partitions and changing disk
layouts. How to calculate with block sizes and get the wanted partition
sizes.
I show the details of my file system in my previous mail, what would be
the exact commands to to resize my /dev/sda1 partition and what would be
the exact command to create a additional partition that fits the new
created free space:
so:
resize2fs /dev/sda1 ????????
sudo /sbin/parted --script /dev/sda \
mkpart primary ?????? 100% \
print
fdisk /dev/sda
# enter 'm, t, 2, ef ,w'
Hope you can show me how to calculate the value to get a 16 MB free
space on /dev/sda with the resize2fs tool.
