Actually, everything that works on the OS is OK for pacemaker. You got 2 options : - use systemd.service for your loadbalancer (for example HAProxy) - create your own script which just requires 'start', 'stop' and 'monitoring' methods so pacemaker can control it Based on my very fast search in the web , haproxy has a ready-to-go resource agent 'ocf:heartbeat:haproxy' , so you can give it a try.

Hi Strahil -- I don't want to proxy the services. I just want NAT redirection at Layer 4, using LVS. Basically, all I need is a good health-checker that works with LVS, like ldirectord does (except newer technology). > -Original Message- > From: Users On Behalf Of Strahil Nikolov > Sent: Sunday, October 4, 2020 2:54 PM > To: Cluster Labs - All topics related to open-source clustering welcomed > > Subject: Re: [ClusterLabs] Open Source Linux Load Balancer with HA and Split > Brain Prevention? > > Actually, everything that works on the OS is OK for pacemaker. > You got 2 options : > - use systemd.service for your loadbalancer (for example HAProxy) > - create your own script which just requires 'start', 'stop' and 'monitoring' > methods so pacemaker can control it > > Based on my very fast search in the web , haproxy has a ready-to-go > resource agent 'ocf:heartbeat:haproxy' , so you can give it a try. > > Best Regards, > Strahil Nikolov > > > > > > > В неделя, 4 октомври 2020 г., 22:41:59 Гринуич+3, Eric Robinson > написа: > > > > > > > > > Greetings! > > > > We are looking for an open-source Linux load-balancing solution that > supports high availability on 2 nodes with split-brain prevention.
