I'm trying to set up an Active/Active cluster (yes, I hear the sounds of kittens dying). Versions:
Scientific Linux 6.2
pacemaker-1.1.6
resource-agents-3.9.2
I'm using cloned IPaddr2 resources:
primitive ClusterIP ocf:heartbeat:IPaddr2 \
params ip="129.236.252.13" cidr_netmask="32" \
op monitor interval="30s"
primitive ClusterIPLocal ocf:heartbeat:IPaddr2 \
params ip="10.44.7.13" cidr_netmask="32" \
op monitor interval="31s"
primitive ClusterIPSandbox ocf:heartbeat:IPaddr2 \
params ip="10.43.7.13" cidr_netmask="32" \
op monitor interval="32s"
group ClusterIPGroup ClusterIP ClusterIPLocal ClusterIPSandbox
clone ClusterIPClone ClusterIPGroup
When both nodes of my two-node cluster are running, everything looks and
functions OK. From "service iptables status" on node 1 (hypatia-tb):
5 CLUSTERIP all -- 0.0.0.0/0 10.43.7.13 CLUSTERIP
hashmode=sourceip-sourceport clustermac=F1:87:E1:64:60:A5 total_nodes=2
local_node=1 hash_init=0
6 CLUSTERIP all -- 0.0.0.0/0 10.44.7.13 CLUSTERIP
hashmode=sourceip-sourceport clustermac=11:8F:23:B9:CA:09 total_nodes=2
local_node=1 hash_init=0
7 CLUSTERIP all -- 0.0.0.0/0 129.236.252.13 CLUSTERIP
hashmode=sourceip-sourceport clustermac=B1:95:5A:B5:16:79 total_nodes=2
local_node=1 hash_init=0
On node 2 (orestes-tb):
5 CLUSTERIP all -- 0.0.0.0/0 10.43.7.13 CLUSTERIP
hashmode=sourceip-sourceport clustermac=F1:87:E1:64:60:A5 total_nodes=2
local_node=2 hash_init=0
6 CLUSTERIP all -- 0.0.0.0/0 10.44.7.13 CLUSTERIP
hashmode=sourceip-sourceport clustermac=11:8F:23:B9:CA:09 total_nodes=2
local_node=2 hash_init=0
7 CLUSTERIP all -- 0.0.0.0/0 129.236.252.13 CLUSTERIP
hashmode=sourceip-sourceport clustermac=B1:95:5A:B5:16:79 total_nodes=2
local_node=2 hash_init=0
If I do a simple test of ssh'ing into 129.236.252.13, I see that I alternately
login into hypatia-tb and orestes-tb. All is good.
Now take orestes-tb offline. The iptables rules on hypatia-tb are unchanged:
5 CLUSTERIP all -- 0.0.0.0/0 10.43.7.13 CLUSTERIP
hashmode=sourceip-sourceport clustermac=F1:87:E1:64:60:A5 total_nodes=2
local_node=1 hash_init=0
6 CLUSTERIP all -- 0.0.0.0/0 10.44.7.13 CLUSTERIP
hashmode=sourceip-sourceport clustermac=11:8F:23:B9:CA:09 total_nodes=2
local_node=1 hash_init=0
7 CLUSTERIP all -- 0.0.0.0/0 129.236.252.13 CLUSTERIP
hashmode=sourceip-sourceport clustermac=B1:95:5A:B5:16:79 total_nodes=2
local_node=1 hash_init=0
If I attempt to ssh to 129.236.252.13, whether or not I get in seems to be
machine-dependent. On one machine I get in, from another I get a time-out. Both
machines show the same MAC address for 129.236.252.13:
arp 129.236.252.13
Address HWtype HWaddress Flags Mask Iface
hamilton-tb.nevis.colum ether B1:95:5A:B5:16:79 C eth0
Is this the way the cloned IPaddr2 resource is supposed to behave in the event
of a node failure, or have I set things up incorrectly?
