Removing Nodes from Clusters
Remove nodes from clusters with the
POST /controller/ejectNodeHTTP method and URI.
Server nodes are typically removed from a cluster when the node is temporarily or permanently down.
/controller/ejectNode cannot remove active nodes.
It can be used only on failed over nodes, nodes in pending state, or nodes that have been recently added or joined but not yet rebalanced into the cluster.
Removing an active node must be done with the
HTTP request syntax:
POST /controller/ejectNode Host: [localhost]:8091 Authorization: Basic xxxxxxxxxxxx Accept: */* Content-Length: xxxxxxxxxx Content-Type: application/x-www-form-urlencoded otpNode=[node@hostname]
Curl request syntax:
curl -u admin:password -d otpNode=[node@hostname] \ http://[localhost]:8091/controller/ejectNode
HTTP request example:
POST /controller/ejectNode Host: 192.168.0.106:8091 Authorization: Basic xxxxxxxxxxxx Accept: */* Content-Length: xxxxxxxxxx Content-Type: application/x-www-form-urlencoded otpNodeemail@example.com
Curl request example:
curl -u Administrator:password -d 'otpNodefirstname.lastname@example.org' \ http://192.168.0.106:8091/controller/ejectNode
