6.3.6. Removing Nodes from Districts

Procedure 6.4. To Remove Nodes from Districts:

1. Run the following commands and fix any problems that are found. This prevents future problems caused by moving a broken gear. On the broker host, run:

   # oo-admin-chk

   On the node hosts, run:

   # oo-accept-node

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

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

4. Remove node2.example.com from the district:

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