# fsck.reiser4(8)

the program for checking and repairing reiser4 filesystem.

## NAME

fsck.reiser4 - the program for checking and repairing reiser4 filesystem.

## SYNOPSIS

**fsck.reiser4** \[ options \] FILE

## DESCRIPTION

**fsck.reiser4** is reiser4 filesystem check and repair program.

## CHECK OPTIONS

- **--check**

  the default action checks the consistency and reports, but does not repair any corruption that it finds.  This option may be used on a read-only file system mount.

- **--fix**

  fixes minor corruptions that do not require rebuilding; sets up correct values of bytes unsupported by kernel in the case of transparent compression.

- **--build-sb**

  fixes all severe corruptions in super blocks, rebuilds super blocks from scratch if needed.

- **--build-fs**

  fixes all severe fs corruptions, except super block ones; rebuilds reiser4 filesystem from the scratch if needed.

- **-L, --logfile**

  forces fsck to report any corruption it finds to the specified logfile rather then on stderr.

- **-n, --no-log**

  prevents fsck from reporting any kind of corruption.

- **-a, --auto**

  automatically checks the file system without any questions.

- **-q, --quiet**

  supresses gauges.

- **-r**

  ignored.

## PLUGIN OPTIONS

- **--print-profile**

  prints the plugin profile. This is the set of default plugins used for all parts of a filesystem -- format, nodes, files, directories, hashes, etc. If --override is specified, then prints modified plugins.

- **-l, --print-plugins**

  prints all plugins libreiser4 know about.

- **-o, --override TYPE=PLUGIN, ...**

  overrides the default plugin of the type "TYPE" by the plugin "PLUGIN" in the plugin profile.

## COMMON OPTIONS

- **-V, --version**

  prints program version

- **-?, -h, --help**

  prints program help

- **-q, --quiet**

  suppress messages.

- **-y, --yes**

  assumes an answer 'yes' to all questions.

- **-f, --force**

  forces fsck to use whole disk, not block device or mounted partition.

- **-p, --preen**

  automatically repair minor corruptions on the filesystem.

- **-c, --cache N**

  tunes number of nodes in the libreiser4 tree buffer cache
