Incorrect multipath.conf setting affects RAC node failover. Settings(features = "1 queue_if_no_path") and/or (no_path_retry = queue) causes the node hang if io path fails. no_path_retry has to be set to the numeric value explicitly. |
All applications using device mapper multipath devices which have contingency plan in case of io path failure. |
RAC node hangs if io path fails. |
In configuration file /etc/multipath.conf,set no_path_retry and polling_interval to the numeric values, for example, "no_path_retry=5" and "polling_interval=10" so as to disable queuing. These values depend on system workload. |
