Hello,
I would configure 3 nodes.For the moment I start with just 2.
I would like check :
* Server up or down
* Iptables service ok or ko
* Squid service ok or ko.
For that I have create :
* authkeys
* ha.cf with that :
use_logd on
keepalive 500ms
deadtime 2
warntime 1
initdead 8
udpport 694
#My gateway
ping 172.16.16.1
bcast eth3
auto_failback on
node poolmail.test.local
node poolmail1.test.local
crm yes
autojoin any

With this configuration it's ok the first time. If I doing after that I have
a problem:
* 1) Poolmail start IPAddr & Squid
* 2) On poolmail I drop the 3128 port. IPaddr & Squid start
on Poolmail1
* 3) If I accept now the 3128 port on Poolmail I don't come
back on this server
* 4) If I drop the 3128 port on Poolmail1 I have on crm_mon
that
Failed actions:
resource_squid_start_0 (node=poolmail.ipanema.local, call=11, rc=-2):
Timed
Out
resource_squid_start_0 (node=poolmail1.ipanema.local, call=11, rc=-2):
Timed
Out
How I can do if I want resolve this problem?
Thanks
Stéphane
