If you are willing to let me to see your file
names, you could send me just the metadata blocks so I can examine file
system image.  The details are in the REPORTING BUGS section of the
e2fsck man page and as well as the RAW IMAGE FILE and QCOW2 IMAGE FILE
sections of the e2image man page, but the short version is:


            e2image -Q /dev/mmcblkp2p2 fs.qcow2
            bzip2 -z fs.qcow2

... and then send me the fs.qcow2.bz file.

If you aren't please try running "dumpe2fs -h /dev/mmcblk2p2" and send
me the output.

Thanks,
