=== 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 | |||
