How to check the delay failover / failback time of the heartbeat / pacemaker using wireshark Hello guys, First of all I want to introduce myself, I am a final student doing research on the heartbeat and pacemaker on Linux. one of the tests I did was to calculate delay failover and failback times from the heartbeat and the pacemaker.

Heartbeat failed = the password stored in secret server is not what is on the account. RPC won't do anything unless using a privileged account that's able to set the password on those accounts w/ hb failures. Common challenge in the PAM world - if no one knows the password, you have to bite the bullet and change it, and see what breaks. heartbeat is a basic high-availability subsystem for Linux-HA. It will run scripts at initialization, and when machines go up or down. This version will also perform IP address takeover using gratuitous ARPs.

Is it possible and supported to configure more than one heartbeat network within Red Hat Clustering without using bonding? Can we use two separate VLANs connected to two separate physical NIC for the heartbeat connections? Environment. Red Hat Enterprise Linux (RHEL) 6 or 7 with the High Availability Add On Heartbeat is a part of Ultra Monkey (The Linux HA Project), and the RPM can be downloaded from The download is small and RPM installation is smooth and simple. However, the document or HOWTO for configuration is hard to find and confusing.

Hi. We are putting in a Red Hat cluster, and I am having diffculty understanding Red Hat's angle on what a heartbeat is. In general terms, a heartbeat is a means of the servers in a cluster letting each other know that they are alive, and should be run over as many network interfaces as possible.
