[Linux-cluster] CS4 / defaults parameters dor heart-beat

[Alain Moulle]

Hi

In the Config file defaults, we can find :

#define DEFAULT_HELLO_TIMER       5     /* Period between HELLO messages */
#define DEFAULT_DEADNODE_TIMER   21     /* If we don't get a message from a
#define DEFAULT_MAX_RETRIES 5           /* Number of times we resend a message */

That seems to mean that the node sends a Hello message
on heart-beat interface every 5s, waits at max 21s before
retry and this 5 times, and if at 5th time , it has no
response in the 21s period , it decides to kill the other node.
Am I right ?

Besides, could you explain for me the JOINREQ, JOINACK, and
JOINCONF notions ?

Thanks
Alain
