slurmdbd.conf(5)

NAME
slurmdbd.conf - Slurm Database Daemon (SlurmDBD) configuration file

DESCRIPTION
/etc/slurmdb.conf is an ASCII file which describes Slurm Database Daemon (SlurmDBD) configuration information.

The file location can be modified at system build time using the DEFAULT_SLURM_CONF parameter. The contents of the file are case insensitive except for the names of nodes and files. Any text following a "#" in the configuration file is treated as a comment through the end of that line. The size of each line in the file is limited to 1024 characters. Changes to the configuration file take effect upon restart of SlurmDbd or daemon receipt of the SIGHUP signal unless otherwise noted.

This file should be only on the computer where SlurmDBD executes and should only be readable by the user which executes SlurmDBD (e.g. "slurm"). This file should be protected from unauthorized access since it contains a database password. The overall configuration parameters available include:

AuthInfo
    Additional information to be used for authentication of communications with the Slurm control daemon (slurmctld) on each cluster. The interpretation of this option is specific to the configured AuthType. In the case of auth/munge, this can be configured to use a Munge daemon specifically configured to provide authentication between clusters while the default Munge daemon provides authentication within a cluster. In that case, this will specify the pathname of the socket to use. The default value is NULL, which results in the default authentication mechanism being used.

AuthType
    Define the authentication method for communications between SLURM components. Acceptable values at present include "auth/none", "auth/authd", and "auth/munge". The default value is "auth/none", which means the UID included in communication messages is not verified. This may be fine for testing purposes, but do not use "auth/none" if you desire any security. "auth/authd" indicates that Brett Chun's authd is to be used (see "http://www.theether.org/authd/" for more information). "auth/munge" indicates that LLNL's Munge system is to be used (this is the best supported authentication mechanism for SLURM, see "http://home.gna.org/munge/" for more information). SlurmDbd must be terminated prior to changing the value of AuthType and later restarted.

DbdAddr
    Name that DbdHost should be referred to in establishing a communications path to the Slurm Database Daemon. This name will be used as an argument to the gethostbyname() function for identification. For example, "elx0000" might be used to designate the ethernet address for node "lx0000". By default the DbdAddr will be identical in value to DbdHost. This value must be equal to the SlurmDbdAddr parameter in the slurm.conf file.

DbdHost
    The name of the machine where the Slurm Database Daemon is executed. This should be a node name without the full domain name (e.g. "lx0001"). This value must be specified.

DbdPort
    The port number that the Slurm Database Daemon (slurmdbd) listens to for work. The default value is SLURMDBD_PORT as established at system build time. If none is explicitly specified, it will be set to 6819. This value must be equal to the SlurmDbdPort parameter in the slurm.conf file.

DebugLevel
    The level of detail to provide the Slurm Database Daemon's logs. Values from 0 to 7 are legal, with `0' being "quiet" operation and `7' being insanely verbose. The default value is 3.

LogFile
    Fully qualified pathname of a file into which the Slurm Database Daemon's logs are written. The default value is none (performs logging via syslog).

MessageTimeout
    Time permitted for a round-trip communication to complete in seconds. Default value is 10 seconds.

PidFile
    Fully qualified pathname of a file into which the Slurm Database Daemon may write its process ID. This may be used for automated signal processing. The default value is "/var/run/slurmdbd.pid".

PluginDir
    Identifies the places in which to look for SLURM plugins. This is a colon-separated list of directories, like the PATH environment variable. The default value is "/usr/local/lib/slurm".

SlurmUser
    The name of the user that the slurmctld daemon executes as. This user must exist on the machine executing the Slurm Database Daemon and have the same user ID as the hosts on which slurmctld execute. For security purposes, a user other than "root" is recommended. The default value is "root".

StorageHost
    Define the name of the host the database is running where we are going to store the data. Ideally this should be the host on which slurmdbd executes.

StorageLoc
    Specify the name of the database as the location where accounting records are written.

StoragePass
    Define the password used to gain access to the database to store the job accounting data.

StoragePort
    The port number that the Slurm Database Daemon (slurmdbd) communicates with the database.

StorageType
    Define the accounting storage mechanism type. Acceptable values at present include "accounting_storage/gold", "accounting_storage/mysql", and "accounting_storage/pgsql". The value "accounting_storage/gold" indicates that account records will be written to Gold (http://www.clusterresources.com/pages/products/gold-allocation-manager.php), which maintains its own database. The value "accounting_storage/mysql" indicates that accounting records should be written to a MySQL database specified by the torageLoc parameter. The value "accounting_storage/pgsql" indicates that accounting records should be written to a PostgreSQL database specified by the StorageLoc parameter. This value must be specified.

StorageUser
    Define the name of the user we are going to connect to the database with to store the job accounting data.
