Remove Replica

Removes a service replica running on a node.

This API simulates a Service Fabric replica failure by removing a replica from a Service Fabric cluster. The removal closes the replica, transitions the replica to the role None, and then removes all of the state information of the replica from the cluster. This API tests the replica state removal path, and simulates the report fault permanent path through client APIs. Warning - There are no safety checks performed when this API is used. Incorrect use of this API can lead to data loss for stateful services. In addition, the forceRemove flag impacts all other replicas hosted in the same process.

Request

Method	Request URI
POST	`/Nodes/{nodeName}/$/GetPartitions/{partitionId}/$/GetReplicas/{replicaId}/$/Delete?api-version=6.0&ForceRemove={ForceRemove}&timeout={timeout}`

Parameters

Name	Type	Required	Location
`nodeName`	string	Yes	Path
`partitionId`	string (uuid)	Yes	Path
`replicaId`	string	Yes	Path
`api-version`	string	Yes	Query
`ForceRemove`	boolean	No	Query
`timeout`	integer (int64)	No	Query

`nodeName`

Type: string
Required: Yes

The name of the node.

`partitionId`

Type: string (uuid)
Required: Yes

The identity of the partition.

`replicaId`

Type: string
Required: Yes

The identifier of the replica.

`api-version`

Type: string
Required: Yes
Default: 6.0

The version of the API. This parameter is required and its value must be '6.0'.

Service Fabric REST API version is based on the runtime version in which the API was introduced or was changed. Service Fabric runtime supports more than one version of the API. This is the latest supported version of the API. If a lower API version is passed, the returned response may be different from the one documented in this specification.

Additionally the runtime accept any version that is higher than the latest supported version up to the current version of the runtime. So if the latest API version is 6.0, but if the runtime is 6.1, in order to make it easier to write the clients, the runtime will accept version 6.1 for that API. However the behavior of the API will be as per the documented 6.0 version.

`ForceRemove`

Type: boolean
Required: No

Remove a Service Fabric application or service forcefully without going through the graceful shutdown sequence. This parameter can be used to forcefully delete an application or service for which delete is timing out due to issues in the service code that prevents graceful close of replicas.

`timeout`

Type: integer (int64)
Required: No
Default: 60
InclusiveMaximum: 4294967295
InclusiveMinimum: 1

The server timeout for performing the operation in seconds. This timeout specifies the time duration that the client is willing to wait for the requested operation to complete. The default value for this parameter is 60 seconds.

Responses

HTTP Status Code	Description	Response Schema
200 (OK)	A successful operation will return 200 status code. A successful operation means that the restart command was received by the replica on the node and it is in the process of restarting.
All other status codes	The detailed error response.	FabricError
