reiserfs resizing - partition sadly dissapeared. Help

[andreas]

Hi all
I tried to resize (make smaller) a reiserfs (linux) partition usin
Suse's yast partitioner

Now I can not mount it, utilities such as debugreiserfs cant se
a partition there, where reiserfsck tries but can't succeed
Of course data is there because I can see it using gre
(grep -a -B2 -A200 "Hi mum" /dev/hdb8

The partition's data occupies about 18.5G
The partition used to occupy about 37G
The hard disk is about 39.5 Gb and there are three mor
partitions there an ext2 of a few megabytes (at the beginning
think
a linux swap of 1Gb and a fat32 of 1Gb
The last one is the reiserfs partition. Before resizing it used t
occupy untill the end of the disk. Until I resized it to 18.5 Gb

i have run partition magic on it. the errors are listed in thi
file here (too long to post it)
http://www.soi.city.ac.uk/~livantes/pm.tx

I ran findpart on the disk (after the resizing) with the followin
results
(the same file but with preserved tabs/spaces is here

I suggest you use Partition Table Doctor to resolve your
problem.The software provides very useful functions:
Backup partition table, Restore partition table, Rebuild
partition table, undelete partition, Fix boot sector,
rebuild mbr,etc.

First thing I recommend you download the demo version of
Partition Table Doctor.( http://www.ptdd.com/download.htm )

Run the program and select "Rebuild Partition Table",
then choose "Interactive" mode.

And completely unreadable too. That's not how it is originally displayed.
Do a proper redirect of that output.
If necessary, load it in the MS-DOS editor and save it.

I ran findpart on the disk (after the resizing) with the following results:
(the same file but with preserved tabs/spaces is here:

What tabs. There are no tabs in findpart output.

Then why not insert it here.
Do you think that people on dial-up will go online for you again
just because you couldn't be bothered to do your homework?

That's completely unreadable, even with fixed spaced font.
Try again, and do your homework this time and set your auto
linebreak to a decent length.

I am trying to understand the output of findpart but it takes time - in
the meantime if anyone can help me on how to restore back that partition...
thanks in advance,

Hi all,
I tried to resize (make smaller) a reiserfs (linux) partition using
Suse's yast partitioner.

Now I can not mount it, utilities such as debugreiserfs cant see
a partition there, where reiserfsck tries but can't succeed.
Of course data is there because I can see it using grep
(grep -a -B2 -A200 "Hi mum" /dev/hdb8)

That does not mean that there is a filesystem left. Indeed it
seems there is not.

I am not familiar with newer versions of Yast. Does it claim
it can resize a partition without data loss?

Some suggestions:

1. If the data on the parttition is important to you, make an image
backup (Essential cat /dev/hdb > <file>) of the disk now, before
messing around with it.
2. What does GNU parted say? It can resize resierfs (at least when
the resierfs libraries are available).
Try to print the partitions with it and check hdb8.
3. What does fdisk -l /dev/hdb say?

Arno

The partition's data occupies about 18.5Gb
The partition used to occupy about 37Gb
The hard disk is about 39.5 Gb and there are three more
partitions there an ext2 of a few megabytes (at the beginning i
think)

Greetings,

Actually, if you managed to loose partition Active@ Partititon Recovery tool might help you to restore it. It worked great for me so you can give it a try also.
