NAME
|
debugreiserfs - The debugging tool for the ReiserFS filesystem. |
SYNOPSIS
|
debugreiserfs [ -dDJmoqpuSV ] [ -j
device ] [ -B file ] [ -1
N ] |
DESCRIPTION
|
debugreiserfs sometimes helps to solve problems with
reiserfs filesystems. When run without options it prints the
super block of the ReiserFS filesystem found on the
device. |
|
is the special file corresponding to the device (e.g
/dev/hdXX for an IDE disk partition or /dev/sdXX for a SCSI
disk partition). |
OPTIONS
|
prints the contents of the journal. The option -p allows it
to pack the journal with other metadata into the
archive. |
|
prints the journal header. |
|
prints the formatted nodes of the internal tree of the
filesystem. |
|
prints the formatted nodes of all used blocks of the
filesystem. |
|
prints the contents of the bitmap (slightly
useful). |
|
prints the objectid map (slightly useful). |
|
takes the list of bad blocks stored in the internal ReiserFS
tree and translates it into an ascii list written to the
specified file. |
|
prints the specified block of the filesystem. |
|
extracts the filesystem's metadata with debugreiserfs
-p /dev/xxx | gzip -c > xxx.gz. None of your data are
packed unless a filesystem corruption presents when the
whole block having this corruption is packed. You send us
the output, and we use it to create a filesystem with the
same strucure as yours using debugreiserfs -u. When
the data file is not too large, this usually allows us to
quickly reproduce and debug the problem. |
|
builds the ReiserFS filesystem image with gunzip -c xxx.gz |
debugreiserfs -u /dev/image of the previously packed
metadata with debugreiserfs -p. The result image is
not the same as the original filesystem, because mostly only
metadata were packed with debugreiserfs -p, but the
filesystem structure is completely recreated. |
|
When -S is not specified -p deals with blocks marked used in
the filesystem bitmap only. With this option set
debugreiserfs will work with the entire
device. |
|
When -p is in use, suppress showing the speed of
progress. |
