List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Chris Horn , Lustre Development List MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: lustre-devel-bounces@lists.lustre.org Sender: "lustre-devel" From: Chris Horn The original intent of the LNET_MSG_STATUS_NETWORK_TIMEOUT health status was to handle cases where the LND was unsure whether the failure was due to the local or remote NI. In this case, we'll want to decrement both the local and remote NI health and allow recovery to ascertain which interface is actually healthy.
