resize reiserfs

["Farkas Barnabás" <kinca@freemail.hu>]

Hello World,

I would like to resize my reiserfs partition. When its finished, I
couldn't mount the partition. I've got error messages
I tried --rebuild-tree

linux:~ # /usr/local/sbin/reiserfsck --rebuild-tree /dev/hda1
reiserfsck 3.6.11 (2003 www.namesys.com)

*************************************************************
** Do not  run  the  program  with  --rebuild-tree  unless **
** something is broken and MAKE A BACKUP  before using it. **
** If you have bad sectors on a drive  it is usually a bad **
** idea to continue using it. Then you probably should get **
** a working hard drive, copy the file system from the bad **
** drive  to the good one -- dd_rescue is  a good tool for **
** that -- and only then run this program.                 **
** If you are using the latest reiserfsprogs and  it fails **
** please  email bug reports to reiserfs-list@namesys.com, **
** providing  as  much  information  as  possible --  your **
** hardware,  kernel,  patches,  settings,  all reiserfsck **
** messages  (including version),  the reiserfsck logfile, **
** check  the  syslog file  for  any  related information. **
** If you would like advice on using this program, support **
** is available  for $25 at  www.namesys.com/support.html. **

No reiserfs metadata found.  If you are sure that you had the reiserfs
on this partition,  then the start  of the partition  might be changed
or all data were wiped out. The start of the partition may get changed
by a partitioner  if you have used one.  Then you probably rebuilt the
superblock as there was no one.  Zero the block at 64K offset from the
start of the partition (a new super block you have just built) and try
to move the start of the partition a few cylinders aside  and check if
debugreiserfs /dev/xxx detects a reiserfs super block. If it does this
is likely to be the right super block version.
If this makes you nervous, try  www.namesys.com/support.html,  and for
$25 the author of fsck,  or a colleague  if he is out,  will  step you
through it all.
