Explanation:
mke2fs – create an ext2/ext3 filesystem -j, Create the filesystem with an ext3 journal. If the -j option is not specified, the default journal parameters will be used to create an appropriately sized journal (given the size of the filesystem) stored within the filesystem. Note that you must be using a kernel, which has ext3 support in order to actually make use of the journal.
