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  trans-
	      parent 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, directo-
	      ries, 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
