Hi,
I have a working 2 node HA setup running on CentOS 6.5 with a very simple
Apache webserver with replicated index.html using DRBD 8.4. The setup is
configured based on the "Clusters from Scratch" Edition 5 with Fedora 13.

node02 only has index.html, no lost+found, and it's a different version of
the file.
Status URL is enabled in both nodes.

Hi,
I'm following the "Clusters from Scratch" guide for Fedora 13, and I've
managed to get a 2 node cluster working with Apache. However, once I tried
to add DRBD 8.4 to the mix, it stopped working.
I've followed the DRBD steps in the guide all the way till "cib commit fs"
in Section 7.4, right b
wrong?

Does this work with
the guide?

Hi,
Is there a tutorial showing how to get a basic Linux HA setup with
replicated storage (via DRBD) working on CentOS 6.5? I want to have mySQL
as the HA resource with the database replicated across the nodes. I've
scoured the web for one but it seems that I get stuck in each one somewhere.
To e
I mean things like firewall settings, as well as services like pcsd,
pacemaker and corosync not starting up automatically sometimes.

Hi,
Is there any way for a Pacemaker/Corosync/PCS setup to send a notification
when it detects that a node in a cluster is down? I read that Pacemaker and
Corosync logs events to syslog, but where is the syslog file in CentOS? Do
they log events such as a failover occurrence?
Thanks.

Hi,
I had a basic HA setup working with 2 nodes previously running a simple
Apache web server on a private local network. However, I'm having trouble
getting it to work right now, and I haven't changed anything other than
rebooting a few times.
Firstly, I've noticed that I need to start the pcsd

Hi,
I'm trying to create a HA cluster with 2 CentOS 7 PCs connected to a
wireless AP. The PCs have the static IP addresses 192.168.0.111 and
192.168.0.112 respectively and hostnames node01 and node02 respectively.
I've tried to create a virtual IP address of 192.168.0.110 using the
