7. Activating inodes

Now it is time for changing some flags of the deleted inodes.

Copy the following 6 lines into a file named "make-debugfs-input".

#!/bin/sh awk '{ print "mi <" $1 ">\n"\ "\n\n\n\n\n\n\n"\ "0\n"\ "1\n"\ "\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n" }'

This will simulate the user input when editing the inodes manually. We will set deletion time to 0 and link count to 1.

Note: I am using debugfs version 1.18 and if you have another version you should check if you need to adjust the number of returns above.

Now change the inodes.

# ./make-debugfs-input < inodes | debugfs -w /dev/hdy1 | tail -c 40

If all went well it should end with "Triple Indirect Block [0] debugfs:".
