e2fsck.conf - Configuration file for e2fsck  


e2fsck.conf is the configuration file for e2fsck(8). It controls the default parameters used by e2fsck(8) when it is creating ext2 or ext3 filesystems.

The e2fsck.conf file uses an INI-style format. Stanzas, or top-level sections, are delimited by square braces: [ ]. Within each section, each line defines a relation, which assigns tags to values, or to a subsection, which contains further relations or subsections. An example of the INI-style format used by this configuration file follows below:        [section1]

               tag1 = value_a

               tag1 = value_b

               tag2 = value_c
       [section 2]

               tag3 = {

                       subtag1 = subtag_value_a

                       subtag1 = subtag_value_b

                       subtag2 = subtag_value_c


               tag1 = value_d

               tag2 = value_e

Comments are delimited by a semicolon (';') or a hash ('#') character at the beginning of the comment, and are terminated by the end of line character. Tags and values must be quoted using double quotes if they contain spaces. Within a quoted string, the standard backslash interpretations apply: "\n" (for the newline character), "\t" (for the tab character), "\b" (for the backspace character), and "\\" (for the backslash character). The following stanzas are used in the e2fsck.conf file. They will be described in more detail in future sections of this document.

This stanza contains general configuration parameters for e2fsck's behavior. [problems] This stanza allows the administrator to reconfigure how e2fsck handles various filesystem inconsistencies.

THE [options] STANZA

The following relations are defined in the [options] stanza.
If this relation is set to a boolean value of true, then if the user interrupts e2fsck using ^C, and the filesystem is not explicitly flagged as containing errors, e2fsck will exit with an exit status of 0 instead of 32. This setting defaults to false.
This boolean relation controls whether or not the interval between filesystem checks (either based on time or number of mounts) should be doubled if the system is running on battery. It defaults to true.

THE [problems] STANZA

Each tag in the [problems] stanza names a problem code specified with a leading "0x" followed by six hex digits. The value of the tag is a subsection where the relations in that subsection override the default treatment of that particular problem code. Note that inappropriate settings in this stanza may cause e2fsck to behave incorrectly, or even crash. Most system administrators should not be making changes to this section without referring to source code. Within each problem code's subsection, the following tags may be used:
This relation allows the message which is printed when this filesystem inconsistency is detected to be overridden.
This boolean relation overrides the default behavior controlling whether this filesystem problem should be automatically fixed when e2fsck is running in preen mode.
This boolean relation overrides the default behavior determining whether or not the filesystem will be marked as inconsistent if the user declines to fix the reported problem.
This boolean relation overrides whether the default answer for this problem (or question) should be "no".
This boolean relation overrides the default behavior controlling whether or not the description for this filesystem problem should be suppressed when e2fsck is running in preen mode.
This boolean relation overrides the default behavior controlling whether or not the description for this filesystem problem should be suppressed when e2fsck is run with the -n option.


The following recipe will prevent e2fsck from aborting during the boot process when a filesystem contains orphaned files. (Of course, this is not always a good idea, since critical files that are needed for the security of the system could potentially end up in lost+found, and starting the system without first having a system administrator check things out may be dangerous.)

               0x040002 = {

                       preen_ok = true

                       description = "@u @i %i. "
