[ClusterLabs] NFS in different subnets

[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, please let me know, but here is the setup I am trying to do if someone can help point me to some information on how the best way is to do this.

Server 1:              DC01-NFS01, 10.0.1.10/24
Server 2:              DC02-NFS01, 10.0.2.10/24
NFS share:           nfs01.domain.local:/opt/nfsmounts using drbd to sync between datacenters
DC01 to DC02 has a 2Gb layer 2 connection between the datacenters

I would like to have pacemaker manage the NFS services on both systems in an active/passive setup where it updates the DNS servers with the active server's IP for nfs01.domain.local. Eventually, we will have a virtual switch in VMWare that I would like pacemaker to update, but for now, the delay in DNS updates will be acceptable for failover.

Thank you in advance for any help you can provide.
