This config has a clone resource, a master/slave resource and a "normal"
resource. I have two nodes (debian and semsor10) and I have serious
problems to understand why happens some situations.
I think this is a normal situation:
Node: semsor10 (2658f3c0-66a9-4348-b598-b9ff49769be7): online
Node: debian (965ec846-da89-468a-b31e-9eea5af911e5): online
Resource Group: IP_ADDR
IPaddr (heartbeat::ocf:IPaddr): Started semsor10
Master/Slave Set: MySQL_Server
mysqld-child:0 (heartbeat::ocf:mysql_slave_master): Master
semsor10
mysqld-child:1 (heartbeat::ocf:mysql_slave_master): Started
debian
Clone Set: pingd
pingd-child:0 (heartbeat::ocf:pingd): Started semsor10
pingd-child:1 (heartbeat::ocf:pingd): Started debian
If I started semsor10 first, Semsor10 went to master well. Then I started
debian and in a moment, all resources disappeared from crm_mon. All
except pingd clone. Then mysql resource is restarted and resources are in
sample out above. IP_ADDR goes down because location constraint, I think
but what about mysql master/slave ?? Why is it going down or making a new
negociation ?? If I have default-resource-stickiness set to INFINITY I
have the same result. I want if a resource is master on a node, this
resource must remains on that node, what is the option to do that ??
Thank you!
