View extended options that were passed into mkfs.ext4

  • 772

I am working with two block devices in a situation where one works with a certain configuration and the other does not. I assume this must be related to subtle differences in the extended options that were passed into respective calls of mkfs.ext4.

How can I inspect those options for existing block devices for a detailed comparison. What other (subtle) differences could perhaps play a role?

    Too vague

    I need details about your problem - you're question is too general/vague. If I knew exactly what problem you were facing, I could try to give you the exact information you need. If you update your question, I'll try to help. The best I can do is provide you with general information.

    Getting ext4 information

    You can get ext4 filesystem information with tune2fs and dumpe2fs. Read their man pages for command line options.

    $ sudo tune2fs -l /dev/sda2
$ sudo dumpe2fs /dev/sda2
