.I device
.SH DESCRIPTION
It looks for reiserfs filesystem on a device, replays transactions
which are to be replayed and either check or repair the filesystem
.TP
.I device
is the special file corresponding to the device (e.g /dev/hdXX for
IDE disk partition or /dev/sdXX for SCSI disk partition).
.SH OPTIONS
.TP
.B --check
This checks filesystem consistency. This is a default action. It may
be used on a filesystem mounted read-only
.TP
.B --rebuild-tree
This rebuilds filesystem tree using leaf nodes found on the
device. Normally, you do not need this, but if you have to rebuild
tree - please backup whole partition first or at least the most
important data if you can mount the partition.
.TP
.B --rebuild-sb
.TP
.B --interactive, -i
This makes \fBreiserfsck\fR to stop after each pass completed.
.TP
.B --quiet, -q
have \fBreiserfsck\fR to not reflect its progress
.TP
.B --nolog, -n
have \fBreiserfsck\fR to not log anything
.TP
\fB--logfile \fIfilename\fR, \fB-l \fI filename
have \fBreiserfsck\fR to put info about found corruptions in logfile
rather than on stderr
.TP
.B --fix-fixable, -x
have \fBreiserfsck\fR to recover corruptions which can be fixed w/o
--rebuild-tree when it is runnig in check mode. Corruptions which can
be fixed so far: bad pointers to data blocks, wrong directory's
st_size and st_blocks, directories entries pointing to nowhere can be
deleted
.TP
.B --fix-non-critical, -o
have \fBreiserfsck\fR to fix: file sizes when they are bigger than
real file size, set file mode to regular file when mode looks wrong
and to try to recover "objectid sharing" problem
.TP
.B -a
When it is set - \fBreiserfsck\fR assumes that it is called by fsck -A
and just returns even if filesystem seems not umounted cleanly
.TP
.B -r
ignored
.TP
.B -V
Prints version and exits
