Does anybody have a clue what is going on - is this a bug or a real problem
with connection that is not notified by system ping.
Is there any way to replace pingd with e.g. a bash script that check the
connectivity and reports a connection status to the heartbeat system (e.g.
resource is stopped or resource has failure)? So a score for a certain resource
group is recalculated and in the case of connectivity problems the resource
group is relocated to other machine. Is this practically possible to apply to
the crm style configuration?
E.g. bash subroutine:
check_connection () {
?node=$1
?[ -z "$node" ] && return 1
?NPACKETS=3
?stat=0
?ping -n -q -c $NPACKETS "$node" >/dev/null 2>&1
?if [ "$?" -ne 0 ]; then
??echo "ERROR: Ping node $node does not answer to ICMP pings"
??stat=1
?else
? echo "INFO: Ping node $node answers to ICMP pings"
?fi
?return $stat
}
I would be grateful for help,
Jarek
