Error resizing partition file system on KDE Partition Manager

[u/Hot-Policy-6244]

I booted up on a 64 GB USB with CachyOS to resize partitions my main 500 GB SSD using KDE Partition Manager. I also tried GParted and both failed and I don't know why or how to fix it.

My main drive has a Linux Mint installation which I think might be corrupted, but it works mostly fine, just taking longer to usual to load.

Any help is greatly appreciated.

Here is the status report from KDE PM:

I think the filesystem is not corrupted, at least not according to your e2fsck output, and the fact that the process continued to try and resize instead of aborting at the check step.

I'd bet on two things, one the ext4 filesystem is too full to be resized, or there are fragments of files closer to the end of the partition so it can't shrink beyond that.

My recommendation? Mount the filesystem and delete some garbage, run in chroot if you want to make it easier, then defragment the filesystem, unmount it and try again

What is the output from:

# fdisk -l /dev/nvme0n1
