For what it's worth; A lot of HA specialists spent a lot of time trying to find the simplest _reliable_ way to do multi-site/geo-replicated HA. I am certain you'll find a simpler solution, but I would also wager that when it counts, it's going to let you down. The only way to make things simpler i

We only have 1 cluster per site so adding additional hardware is not optimal. I feel like I'm trying to use a saw where an axe would be the proper tool. I thank you or your time, but it appears that it may be best for me to write something from scratch for the monitoring and controlling of the fa

Hi Daniel,   You sent this to clusterlabs owners, instead of users. I've changed the CC to send it to the list for a larger discussion.   The biggest problem with stretch clustering is knowing the difference between a link fault and a site loss. Pacemaker Booth

2020-04-17 Thread Daniel Smith
I have been searching how to customize pacemaker to manage NFS servers in separate datacenters, but I am finding older data that suggests this is a bad idea and not much information about how to customize it to do this without the 1 IP being moved back and forth. If this isn't the best tool, ple
