[jboss-jira] [JBoss JIRA] (JGRP-1855) FD_PING2: host failure detection protocol

[ https://issues.jboss.org/browse/JGRP-1855?page=com.atlassian.jira.plugin.... ] Bela Ban updated JGRP-1855: --------------------------- Description: A new protocol similar to FD_PING which detects entire host failures and suspects all members on the failed host. Features are: * Contrary to FD_PING which uses a ring structure, FD_PING2 will have everyone ping everybody else (similar to FD_ALL) ** A structure keeps track of hosts (IP addresses) and members on those hosts *** Example ||192.168.1.2||192.168.1.3||192.168.1.5|| |A,B,C|D,E,F|X,Y,Z| * We sort the members lexically and the *first* member runs a ping against each other IP address, e.g. A pings 192.168.1.3 and 192.168.1.5, D pings 192.168.1.2 and 192.168.1.5 etc * The ping command itself is pluggable and can be a Java class (e.g. using {{InetAddress.isReachable()}}, a script or a command (e.g. {{/sbin/ping}}). * When an entire host is suspected, we suspect *all* clusters members on it ** Example: if B suspects 192.168.1.5, members X, Y and Z are suspected and removed from the view was: A new protocol similar to FD_PING which detects entire host failures and suspects all members on the failed host.
