Hi,
My problem is still here. I search but don't find. I try to change network
cable to put the 3 hosts together on same switch, but same problem.
So with this:
primitive ip_apache_localnet ocf:heartbeat:IPaddr2 \
params ip="10.0.0.99" \
cidr_netmask="32" op monitor interval="30s"
clone cl_ip_apache_localnet ip_apache_localnet \
meta globally-unique="true" clone-max="3" clone-node-max="3"
3 Nodes A B C.
If resource on:
A + B => ok
Only A => ok
Only B => ok
Only C => ok
A + C => random fail
B + C => random fail
A + B + C => random fail
When I say random fail, I do a curl http://10.0.0.99. I can see request
with tcpdump. I can reach all the three hosts. But 1 time on 6 or 7, the
curl request hang. I see with tcpdump the request get in, but no host
answer. I suspect host C but can't find why he don't do the job. If I
ctrl-c & redo the request, I got answer.
I check all firewall / log and don't see any error msg. If someone have a
clue, he's very welcome !
