Gparted will grow (or shrink) the partition. Not the file system.
The file system has to play along, otherwise you'll get a train
wreck.
- Shrinking:
- first, shrink the file system (make sure FS has no data
beyond some block [1]
- then, shrink the partition accordingly
- Growing
- first, grow the partition
- then, grow the filesystem accordingly (i.e. tell the file
system it can use the extra space [2]
[1] Ext2/3/4 supports shrinking. XFS not, according to the FAQ
[2] XFS (and Ext*) support growing
