Template: ocfs2-tools/init Type: boolean Default: false _Description: Would you like to start an OCFS2 cluster (O2CB) at boot time? Template: ocfs2-tools/clustername Type: string Default: ocfs2 _Description: Name of the cluster to start at boot time: Template: ocfs2-tools/heartbeat_threshold Type: string Default: 31 #flag:translate!:6 _Description: O2CB heartbeat threshold: The O2CB heartbeat threshold sets up the maximum time in seconds that a node awaits for an I/O operation. After it, the node "fences" itself, and you will probably see a crash. . It is calculated as the result of: (threshold - 1) x 2. . Its default value is 31 (60 seconds). . Raise it if you have slow disks and/or crashes with kernel messages like: . o2hb_write_timeout: 164 ERROR: heartbeat write timeout to device XXXX after NNNN milliseconds Template: ocfs2-tools/idle_timeout Type: string Default: 30000 _Description: O2CB idle timeout: The O2CB idle timeout (expressed in milliseconds) is the time before a network connection is considered dead. . Its default value is 30000 (30 seconds) and the minimum recommended value is 5000 (5 seconds). Template: ocfs2-tools/keepalive_delay Type: string Default: 2000 _Description: O2CB keepalive delay: The O2CB keepalive delay (expressed in milliseconds) is the maximum time before a keepalive packet is sent. . Its default value is 2000 (2 seconds) and the minimum recommended value is 1000 (1 second). Template: ocfs2-tools/reconnect_delay Type: string Default: 2000 _Description: O2CB reconnect delay: The O2CB reconnect delay (expressed in milliseconds) is the minimum time between connection attempts. . Its default and recommended minimum value is 2000 (2 seconds).
