    used for fault-tolerant computing with Slurm using the optional
    slurmctld/nonstop plugin.
    This plugin provides a means for users to notify Slurm of nodes it believes
    are suspect, replace the job's failing or failed nodes, and extend a job's
    in response to failures.
    The file location can be modified at system build time using the
    DEFAULT_SLURM_CONF parameter or at execution time by setting the SLURM_CONF
    environment variable. The file will always be located in the
    same directory as the \fBslurm.conf\fP file.
    .LP
    Parameter names are case insensitive.
    Any text following a "#" in the configuration file is treated
    as a comment through the end of that line.
    Changes to the configuration file take effect upon restart of
    Slurm daemons, daemon receipt of the SIGHUP signal, or execution
    of the command "scontrol reconfigure" unless otherwise noted.
    The configuration parameters available include:

    .TP
    \fBBackupAddr\fR
    Communications address used for the slurmctld daemon.
    This can either be a hostname or IP address.
    This value would typically be the same as the secondary \fBSlurmctldHost\fR
    in the slurm.conf file, when applicable.

    .TP
    \fBControlAddr\fR
    Communications address used for the slurmctld daemon.
    This can either be a hostname or IP address.
    This value would typically be the same as the \fBSlurmctldHost\fR
    in the slurm.conf file.

    .TP
    \fBDebug\fR
    A number indicating the level of additional logging desired for the plugin.
    The default value is zero, which generates no additional logging.

    .TP
    \fBHotSpareCount\fR
    This identifies how many nodes in each partition should be maintained as
    spare resources.
    When a job fails, this pool of resources will be depleted and then replenished
    when possible using idle resources.
    The value should be a comma delimited list of
    partition and node count pairs separated by a colon.

    .TP
    \fBMaxSpareNodeCount\fR
    This identifies the maximum number of nodes any single job may replace through
    the job's entire lifetime.
    This could prevent a single job from causing all of the nodes in a cluster to
    fail.
    the time replacement resources are requested.
    This time limit extension is in addition to the value calculated using the
    \fBTimeLimitExtend\fR.
    The default value is zero (no time limit extension).
    The value may not exceed 65533 seconds.

    .TP
    \fBTimeLimitDrop\fR
    Specifies the number of minutes that a job can extend its time limit for
    each failed or failing node removed from the job's allocation.
    The default value is zero (no time limit extension).
    The value may not exceed 65533 seconds.

    .TP
    \fBTimeLimitExtend\fR
    Specifies the number of minutes that a job can extend its time limit for
    each replaced node.
    The default value is zero (no time limit extension).
    The value may not exceed 65533 seconds.

    .TP
    \fBUserDrainAllow\fR
    This identifies a comma delimited list of user names or user IDs of users who
    are authorized to drain nodes they believe are failing.
    Specify a value of "ALL" to permit any user to drain nodes.
    By default, no users may drain nodes using this interface.

    .TP
    \fBUserDrainDeny\fR
    This identifies a comma delimited list of user names or user IDs of users who
    are NOT authorized to drain nodes they believe are failing.
    Specifying a value for \fBUserDrainDeny\fR implicitly allows all other users
    to drain nodes (sets the value of UserDrainAllow to "ALL").
