If there isn't any documentation for this yet, can anyone tell me:
* How do I inspect/change my NFS/haproxy/keepalived configuration?
* What is it supposed to look like? Does someone have a working example?
Thank you.

Sorry everyone,
Is there any more detailed documentation on the high availability NFS
functionality in current Ceph?
This is a pretty serious sticking point.
Thank you.

Fellow cephalopods,
I'm trying to get quick, seamless NFS failover happening on my
four-node Ceph cluster.
I followed the instructions here:
https://docs.ceph.com/en/latest/cephadm/services/nfs/#high-availability-nfs
but testing shows that failover doesn't happen. When I placed node 2
("san2") in maintenance mode, the NFS service shut down:

And that's it. The ingress IP didn't move.
More odd, the cluster seems to have placed the ingress IP on node 1
(san1) but seems to be using the NFS service on node 2.
Do I need to more tightly connect the NFS service to the keepalive
and haproxy services, or do I need to expand the ingress services to
refer to multiple NFS services?
Thank you.
