6.3.6. Removing Nodes from Districts

Procedure 6.4. To Remove Nodes from Districts:

   On the node hosts, run:

   # oo-accept-node

   Copy to clipboard
2. Deactivate the node you want to remove to prevent applications from being created on or moved to the node. Existing gears continue running. On the broker host, run:

   # oo-admin-ctl-district -c deactivate-node -n small_district -i node2.example.com

   Copy to clipboard
3. Move all the gears from node2.example.com to node1.example.com by repeating the following command on the broker host for each gear on node2.example.com:

   # oo-admin-move --gear_uuid UUID -i node1.example.com

   Copy to clipboard
4. Remove node2.example.com from the district:

   # oo-admin-ctl-district -c remove-node -n small_district -i node2.example.com
