So as conclusion I managed to mount lustre version 1.6 using 1.4 client, i had to install first 1.4 and then upgrade to 1.6,
you were right  e2fsprogs CFS version worked fine.

Thanks
Cheers

You need to get a CFS version of e2fsprogs. You can download it from
here:
ftp://ftp.clusterfs.com/pub/lustre/other/e2fsprogs

- Kalpak.

In all likelihood, the 'unsupported feature' is 'extents', which
older
debugfs does not understand.
Use e2fsprogs-1.38-cfs1 or later, available from
ftp://ftp.lustre.org/pub/lustre/other/e2fsprogs/

[...]

cmd: debugfs -c -R 'ls -l /' /dev/sde
debugfs 1.39 (29-May-2006)

I guess you don't have installed the suggested e2fsprogs version,
do you?
