- Due to a bug in the resize2fs program, the size of the ext4 file system created on a 16TB block device could not be modified. Consequently, the "device too big" error occurred. This bug has been fixed and file systems residing on 16TB block devices can now be re-sized within the existing file system size limits.
- Prior to this update, the mke4fs command created an ext2 file system by default. In order to create an ext4 file system, the "-t ext4" command-line option had to be inserted. This behavior has been changed, and mke4fs now creates an ext4 file system by default, without the need for extending the command.
