I just run into a problem while resizing a btrfs file system. On an HDD I got two partitions. The first is ~1700GB btrfs partition, the second a 100GB NTFS. I need more space for NTFS so I ran "btrfs filesystem resize -100g /mnt" (https://btrfs.wiki.kernel.org/articles/ ... _8bd8.html). It did work, the partition now is 100GB smaller, but only for Nautilus and the System Monitor. GParted still detects the full 1700GB of partition size. GParted also notes, that it is not capable of resizing btrfs partitions. On Wikipedia it is stated btrfs resizing is working. I am using GParted 0.8.1 while the newest is 0.12.x.
Do you think this is an version issue of GParted? Do you have any experience in resizing a btrfs partition and have any ideas? If it is related to GParted, which version do I need to get it running and how do I get this version installed on my PC?
