Please review: after-pri-pri-now-sec-sec = disconnect No automatic resynchronisation gets performed. One node should drop its net-conf (preferable the node that would become sync-target) DEFAULT. ass-older Auto sync source is the oder primary (curr.behaviour i.t.s.) ass-younger Auto sync source is the younger primary ass-furthest Auto sync source is the node that did more modifications ass-NODENAME Auto sync source is the named node pri-sees-sec-with-higher-gc = disconnect (current behaviour) ass-primary Auto sync source is the current primary panic The current primary panics. The node with the higher gc should take over. Notes: 1) The disconnect actions cause the sync-target or the secondary node to go into StandAllone state. 2) If two nodes in primary state try to connect one of them goes into StandAllone state (=curr. behaviour) 3) As soon as the decission is takes the sync-target addopts the GC of the sync source. [ The whole algorith would also work if both would reset their GCs to <0,0,0...> after the decission, but since we also use the GC to tag the bitmap it is better the current way ] Is this better than try2 ? Should we improve the naming ? "ass" might not be the best choice. Do you think that the naming is constent ? Is it still ambiguous ? -Philipp -- : Dipl-Ing Philipp Reisner Tel +43-1-8178292-50 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Schönbrunnerstr 244, 1120 Vienna, Austria http://www.linbit.com :
