All works fine, but the qdisk seems to beat on the SAN (I/Ops) I adjusted the interval from the default of 1 to 5 and it is still high (san admin is crying) does anyone have best practices for this? its an LSI san and both nodes are mulitpathed to it via 4G FC. </blockquote><div>If it's really a big problem for the SAN, consider adding a third node to the cluster and get rid of the qdisk.
