Revision f5d723fe
| ID | f5d723fedc74c4579a29f603272018aaa34cea64 |
Update 2.3 design doc regarding node group features and behavior.
In particular:
- introduce a "gnt-group" command to hold group-level operations.
- ditch the concept of "default node group", except for single-group
clusters.
- introduce an "alloc_policy" attribute for node groups, indicating
how they should be treated by automated allocation tools.
- introduce a "drain" operation on node groups.
- define iallocator modes for new instance allocation and
inter-group moves (choosing among all groups, or providing a
limiting list).
- indicate and explain that changing the group of a node will be
initially only supported for nodes that are empty.Signed-off-by: Adeodato Simo <dato@google.com>
