Re: [Pacemaker] ERROR: Unable to find nic or netmask.
I mean things like firewall settings, as well as services like pcsd,
pacemaker and corosync not starting up automatically sometimes.

Seems like several things aren't persistent upon reboots, and need to be

What do you mean with "several things" ? Firewall/iptables on CentOS 7? Or
Pacemaker/Corosync/pcs ?

Figured out the problem - the firewall rules are somehow not persistent.
After running the following commands:
iptables -I INPUT -m state --state NEW -p udp -m multiport --dports
5404,5405 -j ACCEPT
iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 2224 -j ACCEPT

Seems like each node thinks it's online and the other is not. I'm
running HA
on apache webserver, and if I access the webpage on node01, I get
node01's
index.html. If I access it on node02, I get node02's index.html. If I
access
it via another PC connected to the same AP, the webpage is unavailable.
What could be wrong?

Re: [Pacemaker] ERROR: Unable to find nic or netmask.
Hi,
After some investigation, it seems that my Apache is having trouble
starting in both nodes. I get the following error message when I try to
restart the service:
Job for httpd.service failed. See 'systemctl status httpd.service' and
'journalctl -xn' for details.
"systemctl status httpd.service" shows the following output:

Re: [Pacemaker] ERROR: Unable to find nic or netmask.
Try to set cidr_netmask=32 for resource only, and let the physical interface's netmask be 24. On Tue, Sep 2, 2014 at 11:27 AM, Sihan Goi wrote: > Got it.

Re: [Pacemaker] ERROR: Unable to find nic or netmask.
Got it. Changed the netmask for both PCs to 255.255.255.0 and changed cidr_netmask to 24 and it works...sort of. It was working for a while, and then I rebooted both PCs, and now each thinks its online and the other is offline.
