Using the Ubuntu 11.10 64-bit Desktop LiveCD, I created a 149.04 GiB partition using gdisk on an unpartitioned SSD. I opened gparted to notice that nothing has been written to the new partition. Then I used mke2fs like this:
sudo mke2fs -t ext4 -O ^has_journal /dev/sda1
Right after, I opened gparted to notice 2.40 GiB has been written to this partition. What has just been written? I thought
makes sure a journal isn't created. So what was actually written to the partition?
