[Pacemaker] help building 2 node config

[Alex Samad - Yieldbroker]

Hi

I sent out an email to help convert an old config. Thought it might better to start from scratch.

I have 2 nodes, which run an application (sort of a reverse proxy).
Node A
Node B

I would like to use OCF:IPaddr2 so that I can load balance IP

# Create ybrp ip address  
pcs resource create ybrpip ocf:heartbeat:IPaddr2 params ip=10.172.214.50 cidr_netmask=24 nic=eth0 clusterip_hash=sourceip-sourceport \
    op start interval="0s" timeout="60s" \
    op monitor interval="5s" timeout="20s" \
    op stop interval="0s" timeout="60s" \
	
# Clone it
pcs resource clone ybrpip2 ybrpip meta master-max="2" master-node-max="2" clone-max="2" clone-node-max="1" notify="true" interleave="true"


This seems to work okay but I tested
On node B I ran this
crm_mon -1 ; iptables -nvL INPUT | head -5 ; ip a ; echo -n [ ; cat /proc/net/ipt_CLUSTERIP/10.172.214.50 ; echo ]

in particular I was watching /proc/net/ipt_CLUSTERIP/10.172.214.50

and I rebooted node A, I  noticed ipt_CLUSTERIP didn't fail over ?  I would have expected to see 1,2 in there on nodeB when nodeA failed

in fact when I reboot nodea it comes back with 2 in there ... that's not good !


pcs resource show ybrpip-clone
 Clone: ybrpip-clone
  Meta Attrs: master-max=2 master-node-max=2 clone-max=2 clone-node-max=1 notify=true interleave=true 
  Resource: ybrpip (class=ocf provider=heartbeat type=IPaddr2)
   Attributes: ip=10.172.214.50 cidr_netmask=24 nic=eth0 clusterip_hash=sourceip-sourceport 
   Operations: start interval=0s timeout=60s (ybrpip-start-interval-0s)
               monitor interval=5s timeout=20s (ybrpip-monitor-interval-5s)
               stop interval=0s timeout=60s (ybrpip-stop-interval-0s)

pcs resource show ybrpip      
 Resource: ybrpip (class=ocf provider=heartbeat type=IPaddr2)
  Attributes: ip=10.172.214.50 cidr_netmask=24 nic=eth0 clusterip_hash=sourceip-sourceport 
  Operations: start interval=0s timeout=60s (ybrpip-start-interval-0s)
              monitor interval=5s timeout=20s (ybrpip-monitor-interval-5s)
              stop interval=0s timeout=60s (ybrpip-stop-interval-0s)



so  I think this has something todo with meta data..



I have another resource
pcs resource create  ybrpstat ocf:yb:ybrp op monitor interval=5s

I want 2 of these one for nodeA and 1 for node B.

I want the IP address to be dependant on if this resource is available on the node.  How can I do that ?
