my disks are also partitioned, i have no idea how, but i want to merge them all into the directory where the 32gb system is located without losing data, can you help me please?

NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
sda           8:0    0 232,9G  0 disk
├─sda1        8:1    0     1G  0 part /boot
├─sda2        8:2    0    32G  0 part /

How did you install arch? That's assuming that you are in fact, actually using arch linux.

well, looky looky somebody who used archinstall and didn't change the root partition size.

but i want to merge them all into the directory where the 32gb system is located without losing data, can you help me please?

1. * plugin external disk big enough to fit the contents of /home *
2. mount /dev/sdb1 /mnt (<= adjust to actual disk)
3. mkdir /mnt/home
3. cp -r /home/* /mnt/home/
4. logout user, login as root
5. umount /home
6. use parted, as stated above. (the wiki page even has a section on extending partitions) delete sda3. extending the root should work without unmounting, but I might be wrong. if not, reboot to a recovery disk and do it there.
7. mv /mnt/home/* /home/
8. edit /etc/fstab and get rid of the line with the disk
9. enjoy!!!

Why I run Arch? To "BTW I run Arch" the guy one grade younger.
And to let my siblings and cousins laugh at Arsch Linux...
