[ClusterLabs] Instant service restart during failback

2017-04-20 Thread Klechomir
Hi List, Been investigating the following problem recently: Have two node cluster with 4 cloned (2 on top of 2) + 1 master/slave services on it (corosync+pacemaker 1.1.15) The failover works properly for both nodes, i.e. when one node is restarted/turned in standby, the other properly takes over

Hi Klaus, It would have been too easy if it was interleave. All my cloned resoures have interlave=true, of course. What bothers me more is that the behaviour is asymmetrical. Regards, Klecho On 20.4.2017 10:43:29 Klaus Wenninger wrote: > On 04/20/2017 10:30 AM, Klechomir wrote: > > Hi List, > > B

[ClusterLabs] Colocation of a primitive resource with a clone with limited copies

2017-04-20 Thread Jan Wrona
Hello, my problem is closely related to the thread [1], but I didn't find a solution there. I have a resource that is set up as a clone C restricted to two copies (using the clone-max=2 meta attribute||), because the resource takes long time to get ready (it starts immediately though), and by

Hi, just for the sake of completeness i'd like to figure out what happens if i start one resource, which is a member of a group, but only this resource. I'd like to see what the other resources of that group are doing. Also if it maybe does not make much sense. Just for learning and understandin
