btrfs rescue fix-device-size
just saved my ass
with all the quirks of the billions of file systems to memorize, i should instead stop with my fdisk command line ego and just use gparted
it will actually resize stuff correctly with custom commands for the actual filesystem in question

@eru I would just be way too lazy to do in command line anyway. I just grab a live usb with gparted and be done with it. Sometimes clicking things together is nice. Eapecially when you need to move partions around or something..

Gparted may still encounter problems sometimes but most of the time it works.

@stefan due to the environment i learned these things, most of my knowledge is very server focused where you dont get a gui for gparted, hence fdisk and parted is all you have
this is why im also used to just a resize2fs and resizing the partition with fdisk and calling it a day, instead of this new modern era of complicated filesystems with gazillions of commands and quirks

@stefan not that that is bad, just miss simplicity or at least a single unified interface
kind of similar to the linux package manager syntax slop these days (which one was it again, apt remove or apt uninstall? :D)
