【文章內(nèi)容簡介】 an zero. [loop] toggles loopback for outbound multicast heartbeats. if enabled, an outbound packet will be looped back and received by the interface it was sent on. (0 or 1) Set this value to zero. mcast eth0 694 1 0 Set up a unicast / udp heartbeat medium ucast [dev] [peeripaddr] [dev] device to send/rcv heartbeats on [peeripaddr] IP address of peer to send packets toucast eth0 About boolean values... Any of the following caseinsensitive values will work for true: true, on, yes, y, 1 Any of the following caseinsensitive values will work for false: false, off, no, n, 0 auto_failback: determines whether a resource will automatically fail back to its primary node, or remain on whatever node is serving it until that node fails, or an administrator intervenes. The possible values for auto_failback are: on enable automatic failbacks off disable automatic failbacks legacy enable automatic failbacks in systems where all nodes do not yet support the auto_failback option. auto_failback on and off are backwards patible with the old nice_failback on setting. See the FAQ for information on how to convert from legacy to on without a flash cut. (., using a rolling upgrade process) The default value for auto_failback is legacy, which will issue a warning at startup. So, make sure you put an auto_failback directive in your file. (note: auto_failback can be any boolean or legacy)auto_failback on Basic STONITH support Using this directive assumes that there is one stonith device in the cluster. Parameters to this device are read from a configuration file. The format of this line is: stonith stonith_type configfile NOTE: it is up to you to maintain this file on each node in the cluster!stonith baytech /etc/ STONITH support You can configure multiple stonith devices using this directive. The format of the line is: stonith_host hostfrom stonith_type params... hostfrom is the machine the stonith device is attached to or * to mean it is accessible from any host. stonith_type is the type of stonith device (a list of supported drives is in /usr/lib/stonith.) params... are driver specific parameters. To see the format for a particular device, run: stonith l t stonith_type Note that if you put your stonith device access information in here, and you make this file publically readable, you39。re asking for a denial of service attack 。) To get a list of supported stonith devices, run stonith L For detailed information on which stonith devices are supported and their detailed configuration options, run this mand: stonith hstonith_host * baytech mylogin mysecretpasswordstonith_host ken3 rps10 /dev/ttyS1 kathy 0 stonith_host kathy rps10 /dev/ttyS1 ken3 0 Watchdog is the watchdog timer. If our own heart doesn39。t beat for a minute, then our machine will reboot. NOTE: If you are using the software watchdog, you very likely wish to load the module with the parameter nowayout=0
