Subject: [PATCH] RH: add mpathconf
|
||||
|
||||
mpathconf is a program (largely based on lvmcomf) to help users
|
||||
configure /etc/multipath.conf and enable or disable multipathing. It
|
||||
has a couple of built-in options that can be set directly from the
|
||||
command line. But, mostly it is used to get a multipath.conf file
|
||||
with the OS defaults, and to enable and disable multipathing via
|
||||
a single command.

+.TH MPATHCONF 8 "June 2010" "" "Linux Administrator's Manual"
|
||||
+.SH NAME
|
||||
+mpathconf - A tool for configuring device-mapper-multipath
|
||||
+.SH SYNOPSIS
|
||||
+.B mpathconf
|
||||
+.RB [\| commands \|]
|
||||
+.RB [\| options \|]
|
||||
+.SH DESCRIPTION
|
||||
+.B mpathconf
|
||||
+is a utility that creates or modifies
|
||||
+.B /etc/multipath.conf.
|
||||
+It can enable or disable multipathing and configure some common options.
|
||||
+.B mpathconf
|
||||
+can also load the
|
||||
+.B dm_multipath
|
||||
+module, start and stop the
|
||||
+.B multipathd
|
||||
+daemon, and configure the
|
||||
+.B multipathd
|
||||
+service to start automatically or not. If
|
||||
+.B mpathconf
|
||||
+is called with no commands, it will display the current configuration, but
|
||||
+will not create of modify
|
||||
+.B /etc/multipath.conf
|
||||
+
|
||||
+The default options for mpathconf are
|
||||
+.B --with_module
|
||||
+The
|
||||
+.B --with_multipathd
|
||||
+option is not set by default. Enabling multipathing will load the
|
||||
+.B dm_multipath
|
||||
+module but it will not immediately start it. This is so
|
||||
+that users can manually edit their config file if necessary, before starting
|
||||
+.B multipathd.
|
||||
+
|
||||
+If
|
||||
+.B /etc/multipath.conf
|
||||
+already exists, mpathconf will edit it. If it does not exist, mpathconf will
|
||||
+create a default file with
|
||||
+.B user_friendly_names
|
||||
+and
|
||||
+.B find_multipaths
|
||||
+set. To disable these, use the
|
||||
+.B --user_friendly_names n
|
||||
+and
|
||||
+.B --find_multipaths n
|
||||
+options
|
||||
+.SH COMMANDS
|
||||
+.TP
|
||||
+.B --enable
|
||||
+Removes any line that blacklists all device nodes from the
|
||||
+.B /etc/multipath.conf
|
||||
+blacklist section. Also, creates
|
||||
+.B /etc/multipath.conf
|
||||
+if it doesn't exist.
|
||||
+.TP
|
||||
+.B --disable
|
||||
+Adds a line that blacklists all device nodes to the
|
||||
+.B /etc/multipath.conf
|
||||
+blacklist section. If no blacklist section exists, it will create one.
|
||||
+.TP
|
||||
+.B --allow \fB<device>\fP
|
||||
+Modifies the \fB/etc/multipath/conf\fP blacklist to blacklist all
|
||||
+wwids and the blacklist_exceptions to whitelist \fB<device>\fP. \fB<device>\fP
|
||||
+can be in the form of MAJOR:MINOR, a wwid, or the name of a device-mapper
|
||||
+device, either a multipath device, or any device on stacked on top of one or
|
||||
+more multipath devices. This command can be used multiple times to allow
|
||||
+multiple devices. \fBNOTE:\fP This action will create a configuration file that
|
||||
+mpathconf will not be able to revert back to its previous state. Because
|
||||
+of this, \fB--outfile\fP is required when using \fB--allow\fP.
|
||||
+.TP
|
||||
+.B --user_friendly_name \fP { \fBy\fP | \fBn\fP }
|
||||
+If set to \fBy\fP, this adds the line
|
||||
+.B user_friendly_names yes
|
||||
+to the
|
||||
+.B /etc/multipath.conf
|
||||
+defaults section. If set to \fBn\fP, this removes the line, if present. This
|
||||
+command can be used along with any other command.
|
||||
+.TP
|
||||
+.B --find_multipaths\fP { \fBy\fP | \fBn\fP }
|
||||
+If set to \fBy\fP, this adds the line
|
||||
+.B find_multipaths yes
|
||||
+to the
|
||||
+.B /etc/multipath.conf
|
||||
+defaults section. If set to \fBn\fP, this removes the line, if present. This
|
||||
+command can be used aldong with any other command.
|
||||
+.TP
|
||||
+.B --outfile \fB<filename>\fP
|
||||
+Write the resulting multipath configuration to \fB<filename>\fP instead of
|
||||
+\fB/etc/multipath.conf\fP.
|
||||
+.SH OPTIONS
|
||||
+.TP
|
||||
+.B --with_module\fP { \fBy\fP | \fBn\fP }
|
||||
+If set to \fBy\fP, this runs
|
||||
+.B modprobe dm_multipath
|
||||
+to install the multipath modules. This option only works with the
|
||||
+.B --enable
|
||||
+command. This option is set to \fBy\fP by default.
|
||||
+.TP
|
||||
+.B --with_multipathd { \fBy\fP | \fBn\fP }
|
||||
+If set to \fBy\fP, this runs
|
||||
+.B service multipathd start
|
||||
+to start the multipathd daemon on \fB--enable\fP,
|
||||
+.B service multipathd stop
|
||||
+to stop the multipathd daemon on \fB--disable\fP, and
|
||||
+.B service multipathd reload
|
||||
+to reconfigure multipathd on \fB--user_frindly_names\fP and
|
||||
+\fB--find_multipaths\fP.
|
||||
+This option is set to \fBn\fP by default.
