NAME

       slurmdbd - Slurm Database Daemon.

SYNOPSIS

       slurmdbd [OPTIONS...]

DESCRIPTION

       slurmdbd  provides  a  secure  enterprise-wide  interface to a database for Slurm. This is
       particularly useful for archiving accounting records.

OPTIONS

       -D     Run slurmdbd in the foreground with logging copied to stdout.

       -h     Help; print a brief summary of command options.

       -n <value>
              Set the daemon's nice value to the specified value, typically a negative number.

       -R[comma separated cluster name list]
              Reset the lft and rgt values of the associations in the given  cluster  list.   Lft
              and  rgt values are used to distinguish hierarchical groups in the slurm accounting
              database. This option should be very rarely used.

       -s     Change working directory of slurmdbd to LogFile path if possible,  or  to  /var/tmp
              otherwise.

       -v     Verbose  operation.  Multiple  v's can be specified, with each 'v' beyond the first
              increasing verbosity, up to 6 times (i.e. -vvvvvv).

       -V     Print version information and exit.

CORE FILE LOCATION

       If slurmdbd is started with the -D option then the  core  file  will  be  written  to  the
       current  working  directory.  Otherwise if LogFile in "slurmdbd.conf" is a fully qualified
       path name (starting with a slash), the core file will be written to the same directory  as
       the log file, provided SlurmUser has write permission on the directory. Otherwise the core
       file will be written to "/var/tmp/" as a last resort. If neither of the above  directories
       have write permission for SlurmUser, no core file will be produced.

SIGNALS

       SIGTERM SIGINT
              slurmdbd will shutdown cleanly, waiting for in-progress rollups to finish.

       SIGABRT
              slurmdbd will perform a core dump, then exit. In-progress operations are killed.

       SIGHUP Reloads the slurm configuration files, similar to 'scontrol reconfigure'.

       SIGUSR2
              Reread the log level from the configs, and then reopen the log file. This should be
              used when setting up logrotate(8).

       SIGCHLD SIGUSR1 SIGTSTP SIGXCPU SIGQUIT SIGPIPE SIGALRM
              These signals are explicitly ignored.

NOTES

       It may be useful to experiment with different slurmctld specific configuration  parameters
       using  a  distinct configuration file (e.g. timeouts). However, this special configuration
       file will not be used by the slurmd daemon or the Slurm programs, unless you  specifically
       tell  each  of them to use it. If you desire changing communication ports, the location of
       the temporary file system, or other parameters used by other Slurm components, change  the
       common configuration file, slurm.conf.
