Thanks Jeff for taking the trouble to respond and your willingness to help
Here are some questions:
- Apparently rados_cluster is gone in 2.8. There is "fs" and 'fs_ng' now
However, I was not able to find a config depicting usage
Would you be able to share your working one ?
- how would one interpret the output of ganesha-rados-grace ?
( what NE and E means and what are the actions one should take when they see it )
- how would one check whether active/active is working properly ( i.e both nfs servers are being used )
I was able to get active passive working using rados_ng and pacemaker
Is there anything pacemaker specific that has to be done to get active-active working ( assuming , of course , ganesha is configured properly?
many thanks
Steven

I've gotten it working, but I wrote most of the code so that shouldn't
be too surprising. The docs are still pretty sketchy at this point, but
most of the info is distilled into the sample config file and the
ganesha-rados-grace manpage.
Writing a real howto is on my to-do list but I'm not sure when I'll get
to it. If you have specific questions, I'm happy to try and answer them
though.
