| These are some simple cluster tools for fixing common allocation |
| problems on Ganeti 2.0 clusters. |
| |
| Note that these tools are most useful for bigger cluster sizes |
| (e.g. more than five or ten machines); at lower sizes, the computations |
| they do can also be done manually. |
| |
| Most of the tools revolve around the concept of keeping the cluster N+1 |
| compliant: this means that in case of failure of any node, the instances |
| affected can be failed over (via ``gnt-node failover`` or ``gnt-instance |
| failover``) to their secondary node, and there is enough memory reserved |
| for this operation without needing to shutdown other instances or |
| rebalance the cluster. |
