Are you trying to shrink it from a live ISO? Try unmounting if you haven’t already.

4

In a live environment they’re never automounted, or at least shouldn’t be. sudo btrfs check --force /dev/nvme0n1p2 was run from within Reborn after I booted back into my installed system.

5

Have you tried using btrfs filesystem resize?

I’ll take a look. I went back into the live Garuda ISO and tried with KDE Partition Manager then With the Garuda installer and both errored out. As for being mounted as I thought the partition wasn’t automounted.

7

Do try out the btrfs command line commands as I stated above and let me know

Update I tried the previous Garuda point release just incase it was something in the live ISO just to see and got the same thing. Will tryout those commands later. Thanks

FWIW, when I need to manage my partitions, I use System Rescue, a live GNU/Linux image, and run gparted from that to resize my partitions, and it has succeeded with btrfs formatted partitions as well as those formatted with ext* (I run Garuda KDE-Lite dual-booted with Windows 11 here). You can get it at System Rescue. I hope it helps. Also, the image contains several other very useful utilities that come in very handy when bad stuff happens.
