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.

       -u     Only  display  the  Slurm  Database  version  and  if conversion is needed and exit without taking
              control. If no conversion is needed 0 is returned, if conversion is needed 1 is returned.

       -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 SIGQUIT
              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 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.
