One more question, for John or anyone:
It looks like Ganesha NFS wants to use dbus to talk to other services
(although I'm not sure how well this works across containers).
I just realised that my build (on AlmaLinux 8 'minimal') did not include
dbus, and Ceph has not installed it.
I have manually installed the default 'dbus' package and its deps, but
this doesn't seem to have had any effect.
* Does Ganesha use dbus to talk to other services, even in a cephadm
* Is there a non-destructive way to make Ganesha retry gsh_dbus_pkginit ?
* Is the default dbus package sufficient, or does Ceph require
specific dbus plugins?

Thanks for getting back to me. I am indeed using cephadm, and I will
dig up those configurations.
Even if Ceph Quincy is current completely incapable of configuring its
own HA failover, I would really like to know what the /imagined/
process would be for detecting a node failure and failing over.
Can you elaborate about those changes that need to happen, or point me
to the forums (ideally the posts_ where this work is broken down in
It's too late for me to change this; I am 100% committed to using Ceph
for HA NFS, no matter what that involves.

The configuration for haproxy, keepalive, and ganesha are generated.
I'm assuming you are using cephadm orchestration. If you want to see
generated configs contain look in /var/lib/ceph/<FSID>/<svc-name>/
under those dirs may be additional subdirectories like etc/ or

It's not simple to customize those files directly. It's not
impossible but it's
probably not worth it (IMO).
Also, speaking only for my personal opinion, the current NFS
situation is one
of OK scale-out but is HA in name only. Fail over is not mature. To
so, changes need to happen throughout the stack including in

the best place to get involved upstream.
I know this probably isn't very satisfactory, but I hope the information
