+.I device
+.SH DESCRIPTION
+\fBReiserfsck\fR searches for a Reiserfs filesystem on a device, replays
+any necessary transactions, and either checks or repairs the file system.
+.TP
+.I device
+is the special file corresponding to a device or to a partition (e.g
+/dev/hdXX for an IDE disk partition or /dev/sdXX for a SCSI disk partition).
+.SH OPTIONS
+.TP
+.B --rebuild-sb
+This option recovers the superblock on a Reiserfs partition. Normally you
+only need this option if mount reports "read_super_block: can't find
+a reiserfs file system" and you are sure that a Reiserfs file system is
+there. But remember that if you have used some partition editor program and
+now you cannot find a filesystem, probably something has gone wrong while
+repartitioning and the start of the partition has been changed. If so,
+instead of rebuilding the super block on a wrong place you should find the
+correct start of the partition first.
+.TP
+.B --check
+This default action checks filesystem consistency and reports, but
+does not repair any corruption that it finds. This option may be
+used on a read-only file system mount.
+.TP
+.B --fix-fixable
+This option recovers certain kinds of corruption that do not require
+rebuilding the entire file system tree (\fB--rebuild-tree\fR). Normally
+you only need this option if the \fB--check\fR option reports
+"corruption that can be fixed with \fB--fix-fixable\fR". This includes:
+zeroing invalid data-block pointers, correcting st_size and st_blocks
+for directories, and deleting invalid directory entries.
+.TP
+.B --rebuild-tree
+This option rebuilds the entire filesystem tree using leaf nodes
+found on the device. Normally you only need this option if the
+\fBreiserfsck \-\-check\fR reports "Running with \fB\-\-rebuild-tree\fR
+is required". You are strongly encouraged to make a backup copy
+of the whole partition before attempting the \fB--rebuild-tree\fR
+option. Once \fBreiserfsck \-\-rebuild-tree\fR is started it must
+finish its work (and you should not interrupt it), otherwise the
+filesystem will be left in the unmountable state to avoid subsequent
+data corruptions.
+.TP
+.B --clean-attributes
+This option cleans reserved fields of Stat-Data items. There were days when
+there were no extended attributes in reiserfs. When they were implemented old
+partitions needed to be cleaned first -- reiserfs code in the kernel did not
+care about not used fields in its strutures. Thus if you have used one of the
+old (pre-attrbutes) kernels with a ReiserFS filesystem and you want to use
+extented attribues there, you should clean the filesystem first.
+.TP
+.B \fB--journal \fIdevice \fR, \fB-j \fIdevice \fR
+This option supplies the device name of the current file system journal.
+This option is required when the journal resides on a separate device
+from the main data device (although it can be avoided with the expert
+option \fB--no-journal-available\fR).
+.TP
+.\" .B --interactive, -i
+.\" This makes \fBreiserfsck\fR to stop after each pass completed.
+.\" .TP
+.B --adjust-size, -z
+This option causes \fBreiserfsck\fR to correct file sizes that
+are larger than the offset of the last discovered byte. This
+implies that holes at the end of a file will be removed. File
+sizes that are smaller than the offset of the last discovered
+byte are corrected by \fB--fix-fixable\fR.
+.TP
+\fB--badblocks \fIfile\fR, \fB-B \fI file\fR
+This option sets the badblock list to be the list of blocks specified in
+the given `file`. The filesystem badblock list is cleared before the new
+list is added. It can be used with \fB--fix-fixable\fR to fix the list of
+badblocks (see \fBdebugreiserfs \-B\fR). If the device has bad blocks, every
+time it must be given with the \fB--rebuild-tree\fR option.
+.TP
+\fB--logfile \fIfile\fR, \fB-l \fI file\fR
+This option causes \fBreiserfsck\fR to report any corruption it finds
+to the specified log file rather than to stderr.
+.TP
+.B --nolog, -n
+This option prevents \fBreiserfsck\fR from reporting any kinds of corruption.
+.TP
+.B --quiet, -q
+This option prevents \fBreiserfsck\fR from reporting its rate of progress.
+.TP
+.B --yes, -y
+This option inhibits \fBreiserfsck\fR from asking you for confirmation after
+telling you what it is going to do. It will assuem you confirm. For safety,
+it does not work with the \fB--rebuild-tree\fR option.
+.TP
+\fB-a\fR, \fB-p\fR
+These options are usually passed by fsck \-A during the automatic checking
+of those partitions listed in /etc/fstab. These options cause \fBreiserfsck\fR
+to print some information about the specified filesystem, to check if error
+flags in the superblock are set and to do some light-weight checks. If these
+checks reveal a corruption or the flag indicating a (possibly fixable)
+corruption is found set in the superblock, then \fBreiserfsck\fR switches
+to the fix-fixable mode. If the flag indicating a fatal corruption is found
+set in the superblock, then \fBreiserfsck\fR finishes with an error.
+.TP
+.B --force, -f
+Force checking even if the file system seems clean.
+.TP
+.B -V
+This option prints the reiserfsprogs version and then exit.
+.TP
+.B -r
+This option does nothing at all; it is provided only for
+backwards compatibility.
+.SH EXPERT OPTIONS
+DO NOT USE THESE OPTIONS UNLESS YOU KNOW WHAT YOU ARE DOING.
+WE ARE NOT RESPONSIBLE IF YOU LOSE DATA AS A RESULT OF THESE
+OPTIONS.
+.TP
+.B \fB\--no-journal-available\fR
+This option allows \fBreiserfsck\fR to proceed when the journal device is
+not available. This option has no effect when the journal is located on
+the main data device. NOTE: after this operation you must use \fBreiserfstune\fR
+to specify a new journal device.
+.TP
+.B --scan-whole-partition, -S
+This option causes \fB--rebuild-tree\fR to scan the whole partition but not only
+the used space on the partition.
+.SH AN EXAMPLE OF USING reiserfsck
+1. You think something may be wrong with a reiserfs partition on /dev/hda1
+or you would just like to perform a periodic disk check.
+
+2. Run \fBreiserfsck \-\-check \-\-logfile check.log /dev/hda1\fR. If \fBreiserfsck
+\-\-check\fR exits with status 0 it means no errors were discovered.
+
+3. If \fBreiserfsck \-\-check\fR exits with status 1 (and reports about fixable
+corruptions) it means that you should run \fBreiserfsck \-\-fix-fixable \-\-logfile
+fixable.log /dev/hda1\fR.
+
+4. If \fBreiserfsck \-\-check\fR exits with status 2 (and reports about fatal
+corruptions) it means that you need to run \fBreiserfsck \-\-rebuild\-tree\fR.
+If \fBreiserfsck \-\-check\fR fails in some way you should also run \fBreiserfsck
+\-\-rebuild-tree\fR, but we also encourage you to submit this as a bug report.
+
+5. Before running \fBreiserfsck \-\-rebuild-tree\fR, please make a backup of
+the whole partition before proceeding. Then run \fBreiserfsck \-\-rebuild-tree
+\-\-logfile rebuild.log /dev/hda1\fR.
+
+6. If the \fBreiserfsck \-\-rebuild-tree\fR step fails or does not recover what
+you expected, please submit this as a bug report. Try to provide as much
+information as possible including your platform and Linux kernel version. We
+will try to help solve the problem.
+.SH EXIT CODES
+\fBreiserfsck\fR uses the following exit codes:
+.br
+\ \fI0\fR \-\ No errors.
+.br
+\ \fI1\fR \-\ File system errors corrected.
+.br
+\ \fI2\fR \-\ Reboot is needed.
+.br
+\ \fI4\fR \-\ File system fatal errors left uncorrected,
+.br
+\ \fBreiserfsck \-\-rebuild-tree\fR needs to be launched.
+.br
+\ \fI6\fR \-\ File system fixable errors left uncorrected,
+.br
+\ \fBreiserfsck \-\-fix-fixable\fR needs to be launched.
+.br
+\ \fI8\fR \-\ Operational error.
+.br
+\ \fI16\fR \-\ Usage or syntax error.
