HP-UX Reference (11i v2 04/09) - 1M System Administration Commands A-M (vol 3)

fsck_hfs(1M) fsck_hfs(1M)

Checking the raw device is almost always faster.

RETURN VALUE

fsck returns the following values:

0 Either no errors were detected or all errors were corrected.

1 A syntax error or other operational error occurred when invoked with the -V option.

4 Root ﬁle system errors were corrected. The system must be rebooted.

8 Some uncorrected errors exist on one or more of the ﬁle systems checked, there was a syntax

error, or some other operational error occurred.

12 A signal was caught during processing.

32 The ﬁle system is unmounted and needs additional checking.

33 The ﬁle system is mounted.

34 The ﬁle system is damaged.

WARNINGS

fsck should not be run on mounted ﬁle systems or on the root device. If you do run on mounted ﬁle sys-

tems, be sure the system is in single-user state (see shutdown(1M)).

The special case of the

-c option, -c 0, will disable all internal caches, which will reduce memory usage

but may impact performance.

The

-F option, from prior releases, has been replaced by the -f option.

AUTHOR
