Yesterday evening, I booted from a Knoppix Live CD... Knoppix supports loop AES
encryption too!
So I set up the loop device and mounted the partition successfully! Then I
copyed everything to a backup partition
and recreate ( on gentoo) the XFS filesystem (mkfs.xfs) and everything is
fine...
I have absolutely no idea why the old xfs partition was not "mountable"!
Very suspect for me... but now I am happy to have my data back!
