Lists all existing node groups in the cluster.
used between the output fields. Both these options are to help
scripting.
+The ``-v`` option activates verbose mode, which changes the display of
+special field states (see **ganeti(7)**).
+
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
+fields will be added to the default list. This allows one 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
-
-alloc_policy
- the current allocation policy for the group
-
-ctime
- the creation time of the group; note that this field contains spaces
- and as such it's harder to parse
+@QUERY_FIELDS_GROUP@
- 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 exactly one argument is given and it appears to be a query filter
+(see **ganeti(7)**), the query result is filtered accordingly. For
+ambiguous cases (e.g. a single field name as a filter) the ``--filter``
+(``-F``) option forces the argument to be treated as a filter.
If no group names are given, then all groups are included. Otherwise,
only the named groups will be listed.
| **rename** {*oldname*} {*newname*}
Renames a given group from *oldname* to *newname*.
+
+
+EVACUATE
+~~~~~~~~
+
+**evacuate** [--iallocator *NAME*] [--to *GROUP*...] {*group*}
+
+This command will move all instances out of the given node group.
+Instances are placed in a new group by an iallocator, either given on
+the command line or as a cluster default.
+
+If no specific destination groups are specified using ``--to``, all
+groups except the evacuated group are considered.
+
+Example::
+
+ # gnt-group evacuate -I hail --to rack4 rack1

+
+TAGS
+~~~~
+
+ADD-TAGS
+^^^^^^^^
+
+**add-tags** [--from *file*] {*groupname*} {*tag*...}
+
+Add tags to the given node group. If any of the tags contains invalid
+characters, the entire operation will abort.
+
+If the ``--from`` option is given, the list of tags will be extended
+with the contents of that file (each line becomes a tag). In this case,
+there is not need to pass tags on the command line (if you do, both
+sources will be used). A file name of ``-`` will be interpreted as
+stdin.
+
+LIST-TAGS
+^^^^^^^^^
+
+**list-tags** {*groupname*}
+
+List the tags of the given node group.
+
+REMOVE-TAGS
+^^^^^^^^^^^
+
+**remove-tags** [--from *file*] {*groupname*} {*tag*...}
+
+Remove tags from the given node group. If any of the tags are not
+existing on the node, the entire operation will abort.
+
+If the ``--from`` option is given, the list of tags to be removed will
+be extended with the contents of that file (each line becomes a tag). In
+this case, there is not need to pass tags on the command line (if you
+do, tags from both sources will be removed). A file name of ``-`` will
+be interpreted as stdin.
