DESCRIPTION
The
fsck
command audits and interactively repairs inconsistent conditions
for HP-UX file systems on mass storage device files identified by
special.
If the file system is consistent,
the number of files on that file system
and the number of used and free blocks are reported.
If the file system is inconsistent,
fsck
provides a mechanism to fix these inconsistencies,
depending on which form of the
fsck
command is used.
special
represents a special device (for example,
/dev/rdisk/disk1_p2).
Options
fsck
recognizes the following options:
- -F FStype
Specify the file system type on which to operate (see
fstyp(1M)
and
fs_wrapper(5)).
If this option is not included on the command line,
then the file system type is determined from the file
/etc/fstab
by matching
special
with an entry in that file.
If there is no entry in
/etc/fstab,
then the file system type is determined from the file
/etc/default/fs.
- -m
Perform a sanity check only.
fsck
will return 0 if the file system is suitable for mounting.
If the file system needs additional checking, the return code is 32.
If the file system is mounted, the return code is 33.
Error codes larger than 33 indicate that the file system is badly damaged.
- -o FSspecific-options
Specify options specific to each file system type.
FSspecific-options
is a list of suboptions and/or keyword/attribute pairs
intended for a file-system-specific version of the command.
See the file-system-specific manual entries for a description of the
specific_options
supported, if any.
- -s
Safe performance mode. To improve performance, a system wide
sync()
will not be issued. This feature is underlying file system
dependent.
- -V
Echo the completed command line, but perform no other action.
The command line is generated by incorporating the
user-specified options and other information derived from
/etc/fstab.
This option allows the user to verify the command line.
RETURN VALUE
The following values are returned by the
-m
option to
fsck:
- 0
Either no errors were detected or all errors were corrected.
- 32
The file system needs additional checking.
- 33
The file system is mounted.
Return values greater that
33
indicate that file system is badly corrupted.
File system specific versions of
fsck
will have their own additional return values (see
fsck_cachefs(1M),
fsck_hfs(1M),
or
fsck_vxfs(1M)).
WARNINGS
This command may not be supported for all file system types.
If this command returns the message "Can't send after socket
shutdown", check with your system administrator to make sure the
fsdaemon
is running properly.
