Subject: User space tool to extract ext3 inode information
Hello!

I need to write a user space tool that can dump
logical block addresses used by every file in a ext3
file system. For example, if file foo uses LBAs 2,3
and file bar uses LBAs 100,102,156, then the ouptut
should read:

FILENAME    LBAs
foo         2, 3
bar         100,102,156

Is there a tool that exists that can do this? If not,
what would be a good strategy to write this tool. I am
learning filesystem programming and would really
appreciate any pointers.

thanks in advance!!

Regards,
-Aravind.

"debugfs -c -R 'stat /path/to/file' /dev/XXX" reports, among other things
the blocks used by that file.

Hi Andreas,

Thanks a bunch for your quick response! I checked the
command and the output is terms of filesytem block
numbers [mine seems to have a 4K block size]. I can
convert this into LBAs in my perl script.

Thanks again.

Regards,

-Aravind.

Hi,guys

 

    In my server, the process kjournald used much more cpu time.

 

    How can I let my system load down?

 

    Thanks.
