ClusAPI Protocol version 2.0 servers do not support this control and MUST fail this method using error code 0x00000001 (ERROR_INVALID_FUNCTION).
The client MUST provide a CLUS_GET_CLUSBFLT_PATHINFO_EX_IN (section 220.127.116.11) structure in the buffer that is designated by lpInBuffer.
After successful completion of the method, the server MUST update the path information to the buffer that is designated by lpOutBuffer. If the lpOutBuffer buffer is not large enough to accommodate the path information, error 0x000000EA (ERROR_MORE_DATA) MUST be returned.
The server SHOULD accept a CLUSCTL_NODE_GET_CLUSBFLT_PATHINFO_EX node control code request if its protocol server state is read-only, and the server MUST accept the request for processing if it is in the read/write state as specified in section 3.1.1.
