Don't forget it works with LVM devices, too. You must be root, but
you can specify an LV:

[root at prophead tmp]# tune2fs -l /dev/mapper/VolGroup00-LogVol00
tune2fs 1.42.7 (21-Jan-2013)
Filesystem volume name:   <none>
Last mounted on:          /
Filesystem UUID:          f07b9552-a738-4e07-9319-150939a5cd42
Filesystem magic number:  0xEF53
Filesystem revision #:    1 (dynamic)
Filesystem features:      has_journal ext_attr resize_inode dir_index 
filetype needs_recovery sparse_super large_file
Filesystem flags:         signed_directory_hash
Default mount options:    user_xattr acl
