problem with reiser3

problem with reiser3

[Marcos Dione]

    hi all. I'm having problems checking a reiser3 filesystem.
reiserfsck says: 

bread: Cannot read the block (27887610): (Input/output error).

    I passed badblocks over the partition and found 61 bad sectors
(which I know is bad), then run reiserfsck -B with the bad blocks file
and got the same, but also this:

create_badblock_bitmap: block number (111550463) points out of fs size (39072080).

    any hints?

    forgot to mention: I tried to resize the fs to the partition size
and got this:

$ sudo resize_reiserfs /dev/sda1
resize_reiserfs 3.6.19 (2003 www.namesys.com)

/dev/sda1 already is of the needed size. Nothing to be done

did you specify reiserfs block size (via option -b) when creating a list
of bad blocks?


then run reiserfsck -B with the bad blocks file

it would be better to create a backup on a spare bigger partition
using dd_rescue (pad not recoverable zones with zeroes), then run
fsck on the created image.

    dunno which is the block size. tried to figure it out, but (from
dmesg trying to mount the partition):
    
ReiserFS: sda1: journal params: device sda1, size 8192, journal first block 18, max trans len 1024, max batch 900, max commit age 30, max trans age 30

    and:

$ sudo reiserfstune /dev/sda1
reiserfstune: Filesystem looks not cleanly umounted, check the consistency first.

    I assume it's the 8192 the kernel reports...

    unluckly I can't. it's a 160 GiB partition and I don't have spare
space.

How much spare space do you have?  You may be able to do some tricks 
with dm_snapshot...

    right now, I have 45 MiB of space in my spare disk. I *could*
(should?) make more space, but can't guarrantee anythung.

debugreiserfs /dev/sda1
then look at Blocksize it the output

That won't be enough.  Worst case, decide whether the data on that 160 
gig partition is worth buying a cheap 200 or 300 gig drive for this backup.
