RHEL / CentOS 5.6 and later officially support ext4 file system [1].
From RHEL / CentOS 5.3 ext4 file system was included as a technology
preview. Ext4 file system tools are in a separate package e4fsprogs,
using uniquely named commands. The standard e2fsprogs commands only
support ext2 and ext3 file systems.
# mkfs.ext4 /dev/sdb3
# tune2fs -l /dev/sdb3
tune2fs 1.39 (29-May-2006)
tune2fs: Filesystem has unsupported feature(s) while trying to open /dev/sdb3
Couldn't find valid filesystem superblock.
# echo $?
1
# tune4fs -l /dev/sdb3
tune4fs 1.41.12 (17-May-2010)
Filesystem volume name: <none>
Last mounted on: <not available>
Filesystem UUID: ba4a9d58-7728-4b47-8a90-80e772615637
Filesystem magic number: 0xEF53
Filesystem revision #: 1 (dynamic)
Filesystem features: has_journal ext_attr resize_inode dir_index filetype extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize
...
For ext4 only, search for the e4fsprogs specific commands first and the
standard e2fsprogs commands second.
