Unable to extend fedora partition

Ask Fedora
1

Long story short, I had both fedora and windows 11 on one ssd. After moving my windows install to another drive, I tried to extend my fedora partition to take up the rest of my drive. However, I keep getting an error to check my btrfs file system in KDE partition manager.

First, you appear to be using kernel 6.17.1. Is that because you are booted from a live media while modifying the partition?

Second, it is not necessary to relocate / expand a btrfs partition. The freed up space can be used to create a new btrfs partition and add it to the existing volume.

I cannot assist with the reported btrfs errors.

When modifying partitions I rely on the gparted tool since it is very powerful and versatile.
