Can Ext4 be extended?

The size of Ext2, Ext3, and Ext4 file systems can be increased by using the resize2fs command when the file system is mounted. The size of an Ext3 file system can also be increased by using the resize2fs command when the file system is unmounted. If the file system is Ext2 or Ext4, you must unmount the file system.
