LIST

~~~~

| **list** [--no-headers] [--separator=*SEPARATOR*]

| [-o *[+]FIELD,...*] [group...]

Lists all existing node groups in the cluster.

The ``--no-headers`` option will skip the initial header line. The

``--separator`` option takes an argument which denotes what will be

used between the output fields. Both these options are to help

scripting.

The ``-o`` option takes a comma-separated list of output fields.

If the value of the option starts with the character ``+``, the new

fields will be added to the default list. This allows to quickly

see the default list plus a few other fields, instead of retyping

the entire list of fields.

The available fields and their meaning are:

name

    the group name

uuid

    the group's UUID

node_cnt

    the number of nodes in the node group

node_list

    the list of nodes that belong to this group

pinst_cnt

    the number of primary instances in the group (i.e., the number of

    primary instances nodes in this group have)

pinst_list

    the list of primary instances in the group

ctime

    the creation time of the group; note that this field contains spaces

    and as such it's harder to parse

    if this attribute is not present (e.g. when upgrading from older

    versions), then "N/A" will be shown instead

mtime

    the last modification time of the group; note that this field

    contains spaces and as such it's harder to parse

serial_no

    the so called 'serial number' of the group; this is a numeric field

    that is incremented each time the node is modified, and it can be

    used to detect modifications

If no group names are given, then all groups are included. Otherwise,

only the named groups will be listed.
