**evacuate** [--iallocator *NAME*] [--to *GROUP*...] {*group*}

|
| 146 |
This command will move all instances out of the given node group. |
|
| 147 |
Instances are placed in a new group by an iallocator, either given on |
|
| 148 |
the command line or as a cluster default. |
|
| 149 |
|
|
| 150 |
If no specific destination groups are specified using ``--to``, all |
|
| 151 |
groups except the evacuated group are considered. |
|
| 152 |
|

Example:: |
|
| 154 |
|
|
| 155 |
# gnt-group evacuate -I hail --to rack4 rack1 |
