The
fsck_msdosfs
utility verifies and repairs
FAT
file systems (more commonly known
as
DOS
file systems).
The first form of
fsck_msdosfs
preens the specified file systems.
It is normally started by
fsck(8)
run from
/etc/rc
during automatic reboot, when a FAT file system is detected.
When preening file systems,
fsck_msdosfs
will fix common inconsistencies non-interactively.
If more serious problems are found,
fsck_msdosfs
does not try to fix them, indicates that it was not
successful, and exits.
The second form of
fsck_msdosfs
checks the specified file systems and tries to repair all
detected inconsistencies, requesting confirmation before
making any changes.
The options are as follows:
|
| -C
|
| |
Compatibility with the corresponding
fsck(8)
option (skip check if clean), defined to no-op.
|
| -F
|
| |
Compatibility with the wrapper
fsck(8)
which seeks to determine whether the file system needs to be cleaned
immediately in foreground, or if its cleaning can be deferred to background.
FAT (MS-DOS) file systems must always be cleaned in the foreground.
A non-zero exit code is always returned for this option.
|
| -M
|
| |
Causes
fsck_msdosfs
to not use
mmap(2)
when checking a FAT32 file system.
This option is mainly for debugging purposes and is not normally necessary.
The
fsck_msdosfs
utility will automatically fall back to use a simple LRU cache of 4 MiB
when it failed to perform
mmap(2),
or when
-M
is specified.
|
| -f
|
| |
Force
fsck_msdosfs
to check
"clean"
file systems when preening.
|
| -n
|
| |
Causes
fsck_msdosfs
to assume
"no"
as the answer to all operator
questions, except
"CONTINUE?".
|
| -p
|
| |
Preen the specified file systems.
|
| -y
|
| |
Causes
fsck_msdosfs
to assume
"yes"
as the answer to all operator questions.
