fsarchiver 0.1.9 (Default branch)
fsarchiver is a system tool that allows you to save the contents of a filesystem to a compressed archive file. The filesystem can be restored on a partition that has a different size, and it can be restored on a different filesystem. Unlike tar/dar, fsarchiver also creates the filesystem when it extracts the data to partitions. Everything is checksummed in the archive in order to protect the data. If the archive is corrupt, you just lose the current file, not the whole archive. License: GNU General Public License v2 Changes:
This release fixes two bugs: it was not possible to restore an ext{2,3.4} partition if it was mounted read/write during the savefs, and opening an archive may fail in restfs for no reason. Image

DEBUGREISERFS(8)					      System Manager's Manual						  DEBUGREISERFS(8)

NAME

       debugreiserfs - The debugging tool for the ReiserFS filesystem.

SYNOPSIS

       debugreiserfs [ -dDJmoqpuSV ] [ -j device ] [ -B file ] [ -1 N ]

       device

DESCRIPTION

       debugreiserfs sometimes helps to solve problems with reiserfs filesystems.  When run without options it prints the super block of the Reis-
       erFS filesystem found on the device.

       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

       -j device
	      prints the contents of the journal. The option -p allows it to pack the journal with other metadata into the archive.

       -J     prints the journal header.

       -d     prints the formatted nodes of the internal tree of the filesystem.

       -D     prints the formatted nodes of all used blocks of the filesystem.

       -m     prints the contents of the bitmap (slightly useful).

       -o     prints the objectid map (slightly useful).

       -B file
	      takes the list of bad blocks stored in the internal ReiserFS tree and translates it into an ascii  list  written	to  the  specified
	      file.

       -1 blocknumber
	      prints the specified block of the filesystem.

       -p     extracts the filesystem's metadata with debugreiserfs -p /dev/xxx | gzip -c > xxx.gz. None of your data are packed unless a filesys-
	      tem 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.

       -u     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 debu-
	      greiserfs -p, but the filesystem structure is completely recreated.

       -S     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.

       -q     When -p is in use, suppress showing the speed of progress.
