From Nicola.Contu at gtt.net Wed Jan 30 08:59:27 2019 From: Nicola.Contu at gtt.net (Nicola Contu) Date: Wed, 30 Jan 2019 08:59:27 +0000 Subject: [Linux-cluster] PCS Cluster Message-ID: Hello, I've setup a cluster using pacemaker and corosync for HA using HAProxy. Two resources : Haproxy and a floating IP. They are running on Centos7 on vmware. The strange thing that happens sometime is that the floating IP won't be pingable from outside the LAN. So for example, a server on the same LAN can ping it but me from my laptop can't. The resource is still active and up on the proxy owning the resource. Attached the log of corosync. Can anyone help?

What is the arp cache on the router when this happens?

Or we need to wait for the next time if someone in Engineering is available to get an ARP (I am not maning routers unfortunately) Do you want me to send you the current ARP? ________________________________ From: linux-cluster-bounces at redhat.com on behalf of Michael Schwartzkopff Sent: Wednesday, January 30, 2019 1:15:01 PM To: linux-cluster at redhat.com Subject: Re: [Linux-cluster] PCS Cluster Am 30.01.19 um 09:59 schrieb Nicola Contu: > Hello, > I've setup a cluster using pacemaker and corosync for HA using HAProxy. > Two resources : Haproxy and a floating IP. > They are running on Centos7 on vmware. > > The strange thing that happens sometime is that the floating IP won't be pingable from outside the LAN. > So for example, a server on the same LAN can ping it but me from my laptop can't. > The resource is still active and up on the proxy owning the resource. > > > Attached the log of corosync. > > Can anyone help? > Thanks > > > It seems to be a network problem.
