Creating an EXT3 Filesystem

As mentioned at the end of the "Creating Filesystems'' section, the same utility is used under the covers to create both EXT2 and EXT3 filesystems; it is simply invoked differently by the mkfs wrapper command. Therefore, the same options are available when creating an EXT3 filesystem.

The easiest way to create an EXT3 filesystem is to use the mkfs wrapper command, specifying ext3 as the type of filesystem that you want to create. Listing 3-7 shows the output of the mkfs command when creating an EXT3 filesystem with default settings. Note that the output of this command is exactly the same as that shown when creating an EXT2 filesystem in the preceding section, with the exception of the following line:

Creating journal (8192 blocks): done

This line indicates that a journal was created for the new partition, and that it is therefore an EXT3 partition.
