Synnefo » snf-ganeti

union of the instances in the two lists must be equal to the set of

instances given in the original request. The successful list of

instances contains elements as follows::

  (instance name, target group name, [chosen node names])

The choice of names is simply for readability reasons (for example,

Ganeti could log the computed solution in the job information) and for

being able to check (manually) for consistency that the generated

opcodes match the intended target groups/nodes. Note that for the

node-evacuate operation, the group is not changed, but it should still

be returned as such (as it's easier to have the same return type for

both operations).

The unsuccessful list of instances contains elements as follows::

  (instance name, explanation)

where ``explanation`` is a string describing why the plugin was not able

to relocate the instance.
