Ronnie Sahlberg f6f7f54bd6 add a new tunable : reclockpingperiod ... once every such interval : * the recovery master on each node will uppdate the "connected" count in the reclock count file (ctdb getreclock) * if the node thinks it is a recovery master but it detects another node that is DISCONNECTED but which still holds a lock to the reclock count file this may mean that we have a split cluster. if that other node that is DISCONNECTED but still holds the lock on hte reclock pnn count file, is MORE connected than the local node, yield the recmaster role and let the other half of the lcuster take over this add a second, last chance mechanism to detect split clusters. IF the cluster is split but GPFS is not yet split, this mechanism makes the largest half of the cluster become the active half. (This used to be ctdb commit 07af425f444531942cce8abff112c1524228d287)		2008-03-03 09:19:30 +11:00

ctdb.h	add a new file <reclock>.pnn where each recovery daemon can lock that byte at offset==pnn to offer an alternative way to detect which nodes are active instead of relying on CONNECTED being accurate.	2008-02-29 12:37:42 +11:00
