I have the following disk setup:
Disk /dev/sda: 53.7GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
14 1049kB 4194kB 3146kB bios_grub
15 4194kB 134MB 130MB fat16 boot, esp
1 134MB 53.7GB 53.6GB ext4
I would like to have a swap partition, but there isn't one as you can see here. So, I would like to take "a piece" of sda1 and make that a new partition. The problem is: I have all my files on sda1 and all the ways I could find to do what I need involved manually selecting the sectors which I don't want to deal with because I don't know which ones contain my data. I would love to use gpart, but I don't have a screen :). It is not a problem for me to make a backup, but I am afraid to lose just "some" data and not realize.
Here is how I imagine doing what I want (but this is in no way a solution because it just randomly allocates first sectors of the drive which will overwrite my data):
sudo parted /dev/sda mkpart primary linux-swap 1 33
sudo mkswap /dev/sda3
sudo swapon /dev/sda3
sudo swapon -s
What could I use to automatically avoid overwriting my files?
