hi and thanks. a primitive can be moved to another node. how can i move (change roles) of drbd:master to the other node ? and will all the depending resources follow ? then i can stop (and start again) corosync on passive node without problem (my tiny experience).
another question: i found a location-constraint (i think it was set by some of the handlers in drbd-config): location drbd:master -INF #uname ne n1 does this mean: drbd must not get promoted on node other than n1 ?! i found this in a situation, when n2 had gone and drbd could not get promoted on n1, so all the other resources did not start. but the problem was not drbd, cause i could manually set it to primary. thanks in advance andreas 2013/6/25 Digimer <li...@alteeve.ca> > On 06/25/2013 07:29 AM, andreas graeper wrote: > > hi, > > maybe again and again the same question, please excuse. > > > > two nodes (n1 active / n2 passive) and `service corosync stop` on active. > > does the node, that is going down, tells the other that he has gone, > > before he actually disconnect ? > > so that there is no reason for n2 to kill n1 ? > > > > on n2 after n1.corosync.stop : > > > > drbd:promote OK > > lvm:start OK > > filesystem:start OK > > but ipaddr2 still stopped ? > > > > n1::drbd:demote works ?! so i would expect that all that depending > > resource should have been > > stopped successfully ?! > > and if not, why ? why should ipaddr2:stop fail > > and if it would fail, can filesystem:stop , lvm:stop , drbd:demote > > succeed ? > > > > how can i find some hint in logs why ipaddr fails to start ? > > > > thanks > > andreas > > If you stop corosync while pacemaker is running, it may well still get > fenced (I've not tested this myself).
