Iam using btrfs for both / and /home and I want to change the lable of those two partitions.
Are they separate partitions or two subvolumes in the same partition?
I think its two subvolumes Iam not sure.
output of lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 931.5G 0 disk
├─sda1 8:1 0 100.1G 0 part /var/cache
│ /var/log
│ /
├─sda2 8:2 0 831.2G 0 part /home
└─sda3 8:3 0 200.2M 0 part /boot/efi
sr0 11:0 1 1024M 0 rom
Those look to be separate partitions. You can use gparted or kde partition manager to change the labels with a gui.
Alternatively, you can do it through the cli if you prefer that approach.
How to do it in CLI?
sudo btrfs filesystem label /home home
sudo btrfs filesystem label / root
Replace root
and home
with what you would like the labels to be.
You may need to reboot to see the labels in lsblk.
Thank you.
