reiserfs 3.5.x partition and corruption - please help

[Rajesh Fowkar]

Hi,

I have got a primary partition of 1.5 GB on which I created reiserfs file
system. I created the file system using mkreiserfs which came with the
reiserfsprogs package distributed with woody. It was working fine for last
6 months.

Today suddenly when I tried to mount and list the contents, it gave me
error saying that some of the files could not be stated. I downloaded the
latest version of e2fsprogs from woody tree and ran reiserfsck /dev/hda2,
error still persisted. I even tried --fix-fixable, --rebuild-tree.

Now my position is I cannot mount the patition at all. I have got lot of
stuff from woody downloaded on my dial-up link in that partition. Please
help me to somehow mount that partition.

Here are some details :

--------------------------------------------------------------------------
debian:~# mount /mnt/hda2/
mount: wrong fs type, bad option, bad superblock on /dev/hda2,
       or too many mounted file systems
debian:~# 
--------------------------------------------------------------------------


--------------------------------------------------------------------------
debian:~# dpkg -l |grep reiser
ii  reiserfsprogs  3.x.1a-2       User-level tools for ReiserFS filesystems
--------------------------------------------------------------------------


--------------------------------------------------------------------------
debian:~# reiserfsck /dev/hda2

<-------------reiserfsck, 2002------------->
reiserfsprogs 3.x.1a

Will read-only check consistency of the filesystem on /dev/hda2
Will put log info to 'stdout'

Hello,

first of all I think that you should start with the latest reiserfprogs tools 
and let debian woody's e2fsprogs alone.

ftp://ftp.namesys.com/pub/reiserfsprogs/pre
reiserfsprogs-3.x.1c_pre1.tar.gz
or
reiserfsprogs-3.x.1b.tar.gz (final)

When all is smooth again you could switch to 3.6 format (kernel 2.4) with 
mount -conv.

Happy Easter!

-Dieter

I only forwarded this to the list, so that all know what's going on.
