CLUSCTL_CLUSTER_SET_CLUSTER_S2D_CACHE_METADATA_RESERVE_BYTES control code

Sets the size of Storage Spaces Direct (S2D) metadata reserve.

Applications use this control code as a ClusterControl parameter.

ClusterControl( hCluster,       // cluster handle
                hHostNode,      // optional node handle
                CLUSCTL_CLUSTER_SET_CLUSTER_S2D_CACHE_METADATA_RESERVE_BYTES, // control code
                lpInBuffer,     // input buffer: property list
                cbInBufferSize, // input buffer size (bytes)
                NULL,           // output buffer (not used)
                0,              // output buffer size (not used)
                NULL );         // output data size (not used)

Parameters

The following control code function parameter is specific to this control code. For complete parameter descriptions, see ClusterControl.

lpInBuffer

Pass a pointer to a ULARGE_INTEGER to set the size of the metadata reserve in bytes.

Return value

Returns one of the following values.

ERROR_SUCCESS

0

The operation completed successfully. The property list is correctly formatted and contains valid data values.

ERROR_INSUFFICIENT_BUFFER

122 (0x7A)

The data area passed to a system call is too small. The actual size of the property list buffer as determined by the Cluster service is larger than the size specified in the cbInBufferSize parameter.

ERROR_INVALID_DATA

13 (0xD)

The data is invalid. The property list is either formatted incorrectly or contains invalid data, such as an out-of-range value.

ERROR_INVALID_PARAMETER

87 (0x57)

The parameter is incorrect. The property list is not formatted correctly.

RPC_X_BAD_STUB_DATA

1783 (0x6F7)

The stub received bad data. The lpInBuffer parameter is NULL.

System error code

If any other value is returned, then the operation failed.
