I am sorry, but I am unable to unpack this metadata snapshot.
I am getting 'unknown magic' message.
How did you compiled your reiserfsprogs?
Can you recompile from scratch please? (with make distclean executed
if doing this from already compiled tree).
Also please verify you can unpack these yourself:
on non-reiserfs fs! (this is important, if all of your FSs are reiserfs do not
do it then)
execute this commands:
touch /nonreiserfs_fs/image
zcat /path/metadata.gz | unpack /nonreiserfs_fs/image

It should print something like this:
<-------------unpack, 2002------------->
reiserfsprogs 3.6.3

There were 5046410 blocks on the device
...#############################################################################
[many lines filled with this]

Bye,

I attach the file hdb2.gz after I create metadata snapshot. I hope that
you can verify without any problem


 and we can verify that reiserfsprogs will work as expected.

My old version of reiserfsprog was 3.6.2 but now is 3.6.3

Respect this I would like another options before if that posible
