NAME

       ctdb.sysconfig - CTDB daemon configuration file

DESCRIPTION

       This file contains configuration that affects the operation of CTDB. This is a
       distribution-specific service configuration file such as /etc/sysconfig/ctdb (Red Hat) or
       /etc/default/ctdb (Debian) and is a shell script (see sh(1)).

GLOBAL CONFIGURATION

       CTDB_INIT_STYLE=debian|redhat|suse
           This is the init style used by the Linux distribution (or other operating system)
           being used. This is usually determined dynamically by checking the system. This
           variable is used by the initscript to determine which init system primitives to use.
           It is also used by some eventscripts to choose the name of initscripts for certain
           services, since these can vary between distributions.

           If using CTDB's event scripts are unable to determine an appropriate default then this
           option can also be placed in a relevant ctdb-script.options(5) file.

           Default: NONE. Guessed, based on features of distribution.

RESOURCE LIMITS

   Maximum number of open files
       CTDB can use a lot of file descriptors, especially when used with Samba. If there are
       thousands of smbd processes connected to CTDB when this can mean that thousands of file
       descriptors are used. For CTDB, it is often necessary to increase limit on the maximum
       number of open files.

       The maximum number of open files should be configured using an operating system mechanism.

       systemd
           The LimitNOFILE=LIMIT option can be used in a unit/service file increase the maximum
           number of open files. See systemd.exec(5) for details.

       SYSV init
           Use a command like ulimit -n LIMIT to increase the maximum number of open files. This
           command can be put in the relevant distribution-specific service configuration file.

   Allowing core dumps
       Many distributions do not allow core dump files to be generated by default. To assist with
       debugging, core files can be enabled. This should be configured using an operating system
       mechanism.

       systemd
           The LimitCORE=0|unlimited option can be used in a unit/service file.  0 disallows core
           files, unlimited allows them. maximum number of open files. See systemd.exec(5) for
           details.

       SYSV init
           Use a command like ulimit -c 0|unlimited to disable or enable core files as required.
           This command can be put in the relevant distribution-specific service configuration
           file.
