Gparted fails to resize btrfs partition that is mounted read-only
As the title says, I attempted to grow a btrfs partition, which failed with some "unknown error" message. The details view shows that this was because that partition happened to be mounted read-only. This means that I ended up in a state where the partition was grown already, but not the FS (which was easy enough to fix up manually, though). I would have expected gparted to either remount the partition writable, or tell me to do that myself.
