fsck.minix \- check consistency of Minix filesystem

.SH SYNOPSIS

.SH DESCRIPTION
|
||
|
|
.B fsck.minix
|
||
|
|
performs a consistency check for the Linux MINIX filesystem.
|
||
|
|
.PP
|
||
|
|
The program assumes the filesystem is quiescent.
|
||
|
|
.B fsck.minix
|
||
|
|
should not be used on a mounted device unless you can be sure nobody is
|
||
|
|
writing to it. Remember that the kernel can write to device when it
|
||
|
|
searches for files.
|
||
|
|
.PP
|
||
|
|
The \fIdevice\fR name will usually have the following form:

If the filesystem was changed, i.e., repaired, then
|
||
|
|
.B fsck.minix
|
||
|
|
will print "FILE SYSTEM HAS CHANGED" and will
|
||
|
|
.BR sync (2)
|
||
|
|
three times before exiting. There is
|
||
|
|
.I no
|
||
|
|
need to reboot after check.
|
||
|
|
.SH WARNING
|
||
|
|
.B fsck.minix
|
||
|
|
should
|
||
|
|
.B not
|
||
|
|
be used on a mounted filesystem. Using
|
||
|
|
.B fsck.minix
|
||
|
|
on a mounted filesystem is very dangerous, due to the possibility that
|
||
|
|
deleted files are still in use, and can seriously damage a perfectly good
|
||
|
|
filesystem! If you absolutely have to run
|
||
|
|
.B fsck.minix
|
||
|
|
on a mounted filesystem, such as the root filesystem, make sure nothing
|
||
|
|
is writing to the disk, and that no files are "zombies" waiting for
|
||
|
|
deletion.
|
||
|
|
.SH OPTIONS
|
||
|
|
.TP
|
||
|
|
\fB\-l\fR, \fB\-\-list\fR

|
||
|
|
.B \-\-repair
|
||
|
|
and serves to answer all of the questions asked with the default. Note
|
||
|
|
that this can be extremely dangerous in the case of extensive filesystem
|
||
|
|
damage.
|
||
|
|
.TP
|
||
|
|
\fB\-v\fR, \fB\-\-verbose\fR

|
.TP
|
||
|
|
\fB\-f\fR, \fB\-\-force\fR

|
Marking is done by the kernel when the filesystem is unmounted.
|
||
|
|
.TP
|
||
|
|

|
||
|

\fB\-h\fR, \fB\-\-help\fR
|
||
|

.SH DIAGNOSTICS
|
||
|
|
There are numerous diagnostic messages. The ones mentioned here are the
|
||
|
|
most commonly seen in normal usage.
|
||
|
|
.PP
|
||
|
|
If the device does not exist,
|
||
|
|
.B fsck.minix
|
||
|
|
will print "unable to read super block". If the device exists, but is not
|
||
|
|
a MINIX filesystem,
|
||
|
|
.B fsck.minix
|
||
|
|
will print "bad magic number in super-block".
|
||
|
|
.SH "EXIT CODES"
|
||
|

|
||
|
