+=== Resize a btrfs filesystem/device ===
+When you resize a file system, you also need to resize the partition (device) it resides on. You cannot resize a mounted partition using '''gparted'''! So you need to unmount it beforehand or use a live manjaro from USB to resize the partition and file system.
+When resizing existing file systems, it is strongly advisable to have current backups. However, resizing is possible without any problems when using '''gparted'''.
+==== shrink ====
+What you need to understand is that you can only safely shrink a file system if it is ''not too full''. Shrinking a file system can take a '''long time''' because BTRFS may need to move data that was in the area to be freed to the remaining area.
+Using '''gparted''' you can safely shrink a BTRFS file system. All necessary steps are taken such as:
+* Mount file system
+* Shrink file system
+* Unmount file system
+* Shrink partition

+==== expand ====
+A BTRFS file system can also be safely expanded with '''gparted'''. All necessary steps are taken such as:
+* Extend partition
+* Mount file system
+* Expand file system
+* Unmount file system
