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