Hi Tim Thanks very much your nice response. Looks I make the mistake.My HBA card is broken,I changed the HBA card, everything is fine.But the QFS performance in cluster in not equal to without cluster,there is a little performance degradation,but I think it is OK for me.
I have gotten serval times help from you.Your suggestion is great helpful to me. I always can learn somethings. Thanks!
