NAME

debugreiserfs 

SYNOPSIS

debugreiserfs[-jdcmos] [-b blocknumber] [-p]device 

DESCRIPTION

It helps sometimes to solve problems with reiserfs filesystems. Being called w/o options it prints super block of reiserfs filesystem found on the device.
device
is the special file corresponding to the device (e.g /dev/hdXX forIDE disk partition or /dev/sdXX for SCSI disk partition).
 

OPTIONS

-j
print contents of journal
-d
print formatted nodes of the filesystem
-c
print contents of direct items
-m
print contents of bitmap (not very useful)
-o
print objectid map (not very useful)
-s
scans the partition and prints a line when any kind of reiserfs formatted nodes found
-b blocknumber
print specified block of the filesystem
-p
This exists to help reiserfsck debugging. If reiserfsck fails -you may extract filesystem metadata with debugreiserfs -p /dev/xxx |gzip-c > xxx.gz. We download that data and make the filesystem similarto your with gunzip -c xxx.gz | unpack /dev/xxx (unpack is includedinto reiserfsprogs package). This usually allows to reproduce anddebug the problem quickly. When data file is not too large.
