debugreiserfs [ -dDJmoqpS ] [ -j device ] [ -B blocknumber ]
device
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 for IDE disk partition or /dev/sdXX for SCSI disk partition). |
-j device
print contents of journal. Also with the option -p it allows to pack journal into archive with other metadata
|
-J |
print journal header. | ||
|
-d |
print formatted nodes of the internal tree of the filesystem | ||
|
-D |
print formatted nodes of all used blocks of the filesystem | ||
|
-m |
print contents of bitmap (not very useful) | ||
|
-o |
print objectid map (not very useful) |
-1 blocknumber
print specified block of the filesystem
|
-p |
Makes debugreiserfs to find filesystem metadata This option 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 similar to your with gunzip -c xxx.gz | unpack /dev/xxx (unpack is included into reiserfsprogs package). This usually allows to reproduce and debug the problem quickly. When data file is not too large. | ||
|
-S |
When -S is not specified -p deals with blocks marked used in the filesystem bitmap. With this option set they will work with whole device. | ||
|
-q |
Suppress showing speed of progress when -p is in use |
