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:

ArchiveDir
If ArchiveScript is not set the slurmdbd will generate a text file that can be read in anytime with sacctmgr load filename. This directory is where the file will be placed archive has ran. Default is /tmp.
ArchiveEvents
Boolean, yes to archive event data, no other wise. Default is no.
ArchiveJobs
Boolean, yes to archive job data, no other wise. Default is no.
ArchiveScript
This script is executed periodically in order to transfer accounting records out of the database into an archive. The script is executed with a no arguments, The following environment variables are set.
SLURM_ARCHIVE_EVENTS
1 for archive events 0 otherwise.
SLURM_ARCHIVE_LAST_EVENT
Time of last event start to archive.
SLURM_ARCHIVE_JOBS
1 for achive jobs 0 otherwise.
SLURM_ARCHIVE_LAST_JOB
Time of last job submit to archive.
SLURM_ARCHIVE_STEPS
1 for archive steps 0 otherwise.
SLURM_ARCHIVE_LAST_STEP
Time of last step start to archive.
SLURM_ARCHIVE_SUSPEND
1 for archive suspend data 0 otherwise.
SLURM_ARCHIVE_LAST_SUSPEND
Time of last suspend start to archive.
ArchiveSteps
Boolean, yes to archive step data, no other wise. Default is no.
ArchiveSuspend
Boolean, yes to archive suspend data, no other wise. Default is no.
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.
DbdBackupHost
The name of the machine where the backup Slurm Database Daemon is executed. This host must have access to the same underlying database specified by the 'Storage' options mentioned below. This should be a node name without the full domain name. I.e., the hostname returned by the gethostname() function cut at the first dot (e.g. use "tux001" rather than "tux001.my.com").
DbdHost
The name of the machine where the Slurm Database Daemon is executed. This should be a node name without the full domain name. I.e., the hostname returned by the gethostname() function cut at the first dot (e.g. use "tux001" rather than "tux001.my.com"). 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 AccountingStoragePort parameter in the slurm.conf file.
DebugLevel
The level of detail to provide the Slurm Database Daemon's logs. Values from 0 to 9 are legal, with `0' being "quiet" operation and `9' being insanely verbose. The default value is 3.
DefaultQOS
When adding a new cluster this will be used as the qos for the cluster unless something is explicitly set by the admin with the create.
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".
PrivateData
This controls what type of information is hidden from regular users. By default, all information is visible to all users. User SlurmUser, root, and users with AdminLevel=Admin can always view all information. Multiple values may be specified with a comma separator. Acceptable values include:
accounts
prevents users from viewing any account definitions unless they are coordinators of them.
jobs
prevents users from viewing job records belonging to other users unless they are coordinators of the association running the job when using sacct.
reservations
restricts getting reservation information to users with operator status and above.
usage
prevents users from viewing usage of any other user. This applys to sreport.
users
prevents users from viewing information of any user other than themselves, this also makes it so users can only see associations they deal with. Coordinators can see associations of all users they are coordinator of, but can only see themselves when listing users.
PurgeEventMonths
Events happening on the cluster over this age are purged from the database. This includeds node down times and such. The time is a numeric value and is a number of months. If zero (default), then job step records are never purged.
PurgeJobMonths
Individual job records over this age are purged from the database. Aggregated information will be preserved indefinitely. The time is a numeric value and is a number of months. If zero (default), then job records are never purged.
PurgeStepMonths
Individual job step records over this age are purged from the database. Aggregated information will be preserved indefinitely. The time is a numeric value and is a number of months. If zero (default), then job step records are never purged.
PurgeSuspendMonths
Records of individual suspend times for jobs over this age are purged from the database. Aggregated information will be preserved indefinitely. The time is a numeric value and is a number of months. If zero (default), then job step records are never purged.
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.
StorageBackupHost
Define the name of the backup host the database is running where we are going to store the data. This can be viewed as a backup solution when the StorageHost is not responding. It is up to the backup solution to enforce the coherency of the accounting information between the two hosts. With clustered database solutions (acitve/passive HA), you would not need to use this feature. Default is none.
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 plugin is not complete and should not be used if wanting to use associations. It will however work with basic accounting of jobs and job steps. If interested in completing please email slurm-dev@lists.llnl.gov. 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.
TrackWCKey
Boolean yes or no. Used to set display and track of the Workload Characterization Key. Must be set to track wckey usage.
