Unfortunately all the answers I found involve GParted. I thought I could be using parted, but apparently the "parted resize" command has some limitations with respect to GParted when working on a partition which has already a filesystem in it ( gives a warning and also can't work on filesystem with some special features like journal, etc... )
I was being able to shrink the filesystem ( ext4 ) by using resize2fs command, but now I don't know how to shrink the partition in order to create a new one.
I also compiled parted 3.0, but in this new version the resize command has been removed altogether...
Should I just use fdisk ? In the man I don't see a resize command there, they say to use parted...
Thanks

tag seems to indicate he's working with Ubuntu Server, which is command-line only..gparted
is just a front-end to the command-lineparted
tool, which the OP already said it didn't work...
