- <para>
- This file contains CTDB configuration variables that are affect
- the operation of CTDB. The default location of this file is
- <filename>/usr/local/etc/ctdb/ctdbd.conf</filename>.
- </para>

- <para>
- This file is a shell script (see
- <citerefentry><refentrytitle>sh</refentrytitle>
- <manvolnum>1</manvolnum></citerefentry>) but is usually limited
- to simple variable assignments and shell-style comments.
- </para>
-
- <para>
- CTDB configuration variables are grouped into several categories below.
- </para>
-
- <para>
- Variables defined in this document can also be set in a
- distribution-specific configuration file such as
- <filename>/etc/sysconfig/ctdb</filename> (Red Hat) or
- <filename>/etc/default/ctdb</filename> (Debian). However, these
- files should be reserved for variables used by the initscript.
- A historical alternative is
- <filename>/usr/local/etc/ctdb/sysconfig/ctdb</filename> - this is
- deprecated.

- <varlistentry>
- <term>syslog<optional>:<parameter>METHOD</parameter></optional></term>
- <listitem>
- <para>
- CTDB will log to syslog. By default this will use
- the syslog(3) API.
- </para>
- <para>
- If METHOD is specified then it specifies an
- extension that causes logging to be done in a
- non-blocking fashion. This can be useful under
- heavy loads that might cause the syslog daemon to
- dequeue messages too slowly, which would otherwise
- cause CTDB to block when logging. METHOD must be
- one of:
- </para>
- <variablelist>
- <varlistentry>
- <term>nonblocking</term>
- <listitem>
- <para>
- CTDB will log to syslog via

- mode.
- </para>
- </listitem>
- </varlistentry>
- <varlistentry>
- <term>udp</term>
- <listitem>
- <para>
- CTDB will log to syslog via UDP to
- localhost:514. The syslog daemon must be
- configured to listen on (at least)
- localhost:514. Most implementations will log
- the messages against hostname "localhost" -
- this is a limit of the implementation for
- compatibility with more syslog daemon
- implementations.
- </para>
- </listitem>
- </varlistentry>
- <varlistentry>
- <term>udp-rfc5424</term>
- <listitem>
- <para>
- As with "udp" but messages are sent in RFC5424
- format. This method will log the correct
- hostname but is not as widely implemented in
- syslog daemons.

- <listitem>
- <para>
- Defaults to no.

- <para>
- Usually CTDB runs with real-time priority. If you are running
- CTDB on a platform that does not support real-time priority,
- you can set this.
- </para>
- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>CTDB_NODE_ADDRESS=<parameter>IPADDR</parameter></term>
- <listitem>
- <para>
- IPADDR is the private IP address that ctdbd will bind to.
- </para>
- <para>
- By default ctdbd will select the first address from the
- nodes list that in can bind to. See also the
- <citetitle>Private address</citetitle> section in
- <citerefentry><refentrytitle>ctdb</refentrytitle>
- <manvolnum>7</manvolnum></citerefentry>.
- </para>
- <para>
- This option is only required when automatic address
- detection can not be used. This can be the case when
- running multiple ctdbd daemons/nodes on the same physical
- host (usually for testing), using InfiniBand for the
- private network or on Linux when sysctl
- net.ipv4.ip_nonlocal_bind=1.

- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>CTDB_RECOVERY_LOCK=<parameter>LOCK</parameter></term>
- <listitem>
- <para>
- LOCK specifies the cluster-wide mutex used to detect and
- prevent a partitioned cluster (or "split brain").
- </para>
- <para>
- No default, but the default configuration file specifies
- <filename>/some/place/on/shared/storage</filename>, which
- should be change to a useful value.
