Sorry, just another question:

- in my installation of gluster 3.7.1 the command gluster features.ganesha 
enable does not work:

# gluster features.ganesha enable
unrecognized word: features.ganesha (position 0)

Which version has full support for it?

Sorry. This option has recently been changed. It is now

$ gluster nfs-ganesha enable



- in the documentation the ccs and cman packages are required, but they seems 
not to be available anymore on CentOS 7 and similar, I guess they are not 
really required anymore, as pcs should do the full job

Thanks,

        Alessandro

Looks like so from http://clusterlabs.org/quickstart-redhat.html. Let us know if it doesn't work.

Thanks,
Soumya

Hi,

Please find the slides of the demo video at [1]

We recommend to have a distributed replica volume as a shared volume for better 
data-availability.

Size of the volume depends on the workload you may have. Since it is used to 
maintain states of NLM/NFSv4 clients, you may calculate the size of the volume 
to be minimum of aggregate of
(typical_size_of'/var/lib/nfs'_directory + 
~4k*no_of_clients_connected_to_each_of_the_nfs_servers_at_any_point)

We shall document about this feature sooner in the gluster docs as well.

Thanks,
Soumya

Hi,
I have seen the demo video on ganesha HA, 
https://www.youtube.com/watch?v=Z4mvTQC-efM
However there is no advice on the appropriate size of the shared volume. How is 
it really used, and what should be a reasonable size for it?
Also, are the slides from the video available somewhere, as well as a 
documentation on all this? I did not manage to find them.
Thanks,

        Alessandro
