Try to fix a broken ReiserFS / Data Recovering?
Hi there, i am very new to this list, i just signed up today, because i got some problems with a broken ReiserFS since yesterday. _The problem_ Yesterday my Router/Server (Suse Linux 8.1, 40GB IDE HDD with ReiserFS) hang up. After a reboot it only starts to load stage2 of Grub, which fails and ends up in the grub minimal bash. _What i do to resolve the problem_ I downloaded the Suse Live-CD 9.1 and did a clean boot from it. I Try to mount the volume, what end up with Falscher Dateisystemtyp, ungültige Optionen, der »Superblock« von /dev/hdb2 ist beschädigt oder es sind zu viele Dateisysteme eingehängt (=corrupt superblock) Then I tried reiserFs Check wich ends up in: Bad root block 0. (--rebuild-tree did not complete). Ok, i followed the instructions in the following bad block info text and did a reiserFs -B badblocksfile --rebuild-tree. Wich aborts and said badblock in . Right now i am doing a complete Backup image with dd_rescue, after this i would like to run /sbin/badblocks, as explained in the Faq (http://www.namesys.com/bad-block-handling.html) and run then reiserfs -B again. _My Questions_ - Am i right in doing these actions to try to resolve the problem of my harddisk, and HOPEFULLY to recover the Data? - Is there anything i should try/do else? - Do you now somebody/any company, wich do a real data-recovering von ReiserFS Disk? Its only 40GB but there are some data on it wich are very important. (don't ask after the backups, they broke last week on the extern hdd! :(( ) Hopefully you guys can help me, thanks a lot :) Lars

RE: Try to fix a broken ReiserFS / Data Recovering?
Hi, The following paragraph is snippet of reiserfsck man page. AN EXAMPLE OF USING reiserfsck 1. You think something may be wrong with a reiserfs partition on /dev/hda1 or you would just like to perform a periodic disk check. 2. Run reiserfsck --check --logfile check.log /dev/hda1. If reiserfsck --check exits with status 0 it means no errors were discovered. 3. If reiserfsck --check exits with status 1 (and reports about fixable corruptions) it means that you should run reiserfsck --fix-fixable --logfile fixable.log /dev/hda1. 4. If reiserfsck --check exits with status 2 (and reports about fatal corruptions) it means that you need to run reiserfsck --rebuild-tree. If reiserfsck --check fails in some way you should also run reiserfsck --rebuild-tree, but we also encourage you to submit this as a bug report. 5. Before running reiserfsck --rebuild-tree, please make a backup of the whole partition before proceeding. Then run reiserfsck --rebuild-tree --logfile rebuild.log /dev/hda1. 6. If the reiserfsck --rebuild-tree step fails or does not recover what you expected, please submit this as a bug report. Try to provide as much information as possible including your platform and Linux kernel version. We will try to help solve the problem. EXIT CODES reiserfsck uses the following exit codes: 0 - No errors. 1 - File system errors corrected. 2 - Reboot is needed. 4 - File system fatal errors left uncorrected, reiserfsck --rebuild-tree needs to be launched. 6 - File system fixable errors left uncorrected, reiserfsck --fix-fixable needs to be launched. 8 - Operational error. 16 - Usage or syntax error. AUTHOR This version of reiserfsck has been written by Vitaly Fertman [EMAIL PROTECTED]. BUGS Please report bugs to the ReiserFS developers [EMAIL PROTECTED], providing as much information as possible--your hardware, kernel, patches, settings, all printed messages, the logfile; check the syslog file for any related information. TODO Faster recovering, signal handling. From the fourth point What I understood is, failure of reiserfsck --check with error code other than 1 and 2 is a bug. Is it correct ? And the last table tells that reiserfsck still not hadling signals. Is it correct ? Regards, Masthan -Original Message- From: Vladimir V.

Re: Try to fix a broken ReiserFS / Data Recovering?
I had this problem too with older SuSE versions (7.? - 8.?), its a shame that nobody found this bug for such a long time. I too saw the same behaviour you described, but for me it has always helped to just re-install grub. Boot up with a rescue-cd and simply re-install grub or use yast to do so. But maybe your problem is different and its quite unlikly to work now that reiserfschk boild out :-/ lg Clemens 2006/6/19, Lars Wolff [EMAIL PROTECTED]: Hi Vladimir!
