reiserfsck - "out of disk space" - Aborted. Help needed

[Jens Benecke <jens@spamfreemail.de>]

Hello,

I have a reiserfs partition on a SuSE 10.0 machine (kernel 
2.6.13-15.10-default, by SuSE) that  was suddenly out of disk space. One 
file on the disk was inaccessible  and syslog showed me

md2: warning: vs-13060: reiserfs_update_sd: stat data of object [420 48207
0x0 SD] (nlink == 1)
 not found (pos 1)

hundreds of times.

reiserfsck (3.6.18, by SuSE) --fix-fixable wanted to run --rebuild-tree, so 
I did. Rebuild-tree worked for over four hours (the partition is ~130GB) 
and then exited with "out of disk space".

I searched the list archives for a bit more info and the only solution I 
found so far was to copy the disk to a bigger harddisk, enlarge the 
filesystem and do another reiserfsck there.

Another hint was to use reiserfsprogs-3.6.20. Will these be able to repair 
a full file system?

Or is there a way to delete a file off this file system (perhaps using 
debugreiserfs) before fixing it?

Thank you!



server:/ # reiserfsck --rebuild-tree /dev/md2

*************************************************************
** 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. **

Will rebuild the filesystem (/dev/md2) tree
Will put log info to 'stdout'

Do you want to run this program?[N/Yes] (note need to type Yes if you
do):Yes
