Module nodeset

source code

Usage: nodeset [COMMAND] [OPTIONS] [ns1 [-ixX] ns2|...]

Commands:
    --count, -c <nodeset> [nodeset ...]
        Return the number of nodes in nodesets.
    --expand, -e <nodeset> [nodeset ...]
        Expand nodesets to separate nodes.
    --fold, -f <nodeset> [nodeset ...]
        Compact/fold nodesets (or separate nodes) into one nodeset.
    --list, -l
        List node groups (see --groupsource).
    --regroup, -r <nodeset> [nodeset ...]
        Fold nodes using node groups (see --groupsource).
    --groupsources
        List all configured group sources (see groups.conf(5)).
Options:
    --all, -a
        Call external node groups support to display all nodes.
    --autostep=<number>
        Specify auto step threshold number when folding nodesets.
        If not specified, auto step is disabled.
        Example: autostep=4, "node2 node4 node6" folds in node[2,4,6]
                 autostep=3, "node2 node4 node6" folds in node[2-6/2]
    --help, -h
        This help page.
    --quiet, -q
        Quiet mode, hide any parse error messages (on stderr).
    --rangeset, -R
        Switch to RangeSet instead of NodeSet. Useful when working on
        numerical cluster ranges, eg. 1,5,18-31.
    --groupsource, -s <GroupSource>
        Specify group source (ie. section to use in groups.conf(5)).
    --groupbase, -G
        Do not display group source prefix (always "@groupname").
    --separator=<string>, -S <string>
        Specify separator string for expanding nodesets (default: ' ').
    --version, -v
        Show ClusterShell version and exit.
Operations (default is union):
        The default operation is the union of node or nodeset.
    --exclude=<nodeset>, -x <nodeset>
        Exclude provided node or nodeset.
    --intersection, -i
        Calculate nodesets intersection.
    --xor, -X
        Calculate symmetric difference (XOR) between two nodesets.
