Without this patch, the NFSv4.1 pNFS client shared a single TCP connection for all DSs that resided on the same machine. This made disabling one of the DSs impossible. Although unlikely, it is possible that the storage subsystem has failed in such a way that the storage for one DS on a machine is no longer functioning correctly, but the storage used by another DS on the same machine is still ok. For this case, it would be nice if a system can fail one of the DSs without failing them all. This patch changes the default behaviour to use separate TCP connections for each DS even if they reside on the same machine. I do not believe that this will be a problem for extant pNFS servers, but a sysctl can be set to restore the old behaviour if this change causes a problem for an extant pNFS server. This patch only affects the NFSv4.1 pNFS client. MFC after: 2 weeks |
