slurmdbd [OPTIONS...]

slurmdbd (Slurm Database Daemon) provides a secure enterprise-wide database interface for Slurm workload manager. It is essential for archiving accounting records, tracking job history, usage statistics, and user/account associations across a cluster.
The daemon handles database connections, manages accounting data storage, and provides fair-share scheduling information to slurmctld. It typically runs on a dedicated host with access to the accounting database (MySQL/MariaDB).

-D

Run daemon in foreground with logging to stdout

Display help and brief summary of options

Set daemon nice value (typically negative)

Change working directory to LogFile path or /var/tmp

Display database version and conversion status, then exit

Verbose operation (up to 6 levels with multiple v's)

Print version information and exit

/etc/slurm/slurmdbd.conf

Database daemon configuration specifying database connection parameters, authentication settings, and logging options.

Main Slurm configuration referenced for cluster-wide settings and AccountingStorageHost.

SIGTERM, SIGINT, SIGQUIT

Graceful shutdown with rollup completion

Reload configuration files

Reread log level and reopen log file (useful for logrotate)

Requires proper configuration in slurmdbd.conf before starting. Database must be accessible and properly configured. Should run on a host separate from compute nodes for reliability. Uses significant memory for large clusters with extensive job history.

slurmdbd is part of Slurm (Simple Linux Utility for Resource Management), developed at Lawrence Livermore National Laboratory starting in 2002. The database daemon was added to support enterprise-level accounting and fair-share scheduling. Slurm is now maintained by SchedMD and is used on many of the world's largest supercomputers.
