With this release, you can override any parameter in the NFS_CORE_PARAM block section in the `ganesha.conf` file by setting the variable `ganesha_core_param_overrides` in group_vars/all.yml and update client-related configuration.

Description Goutham Pacha Ravi 2021-03-22 18:30:11 UTC

Description of problem:

This request is similar to that in https://bugzilla.redhat.com/show_bug.cgi?id=1925646 and originates from Red Hat OpenStack's use of nfs-ganesha to provide CephFS shares via an NFS gateway for multi-tenant clouds. 

Currently, there are a set of sensible default configuration options in the nfs-ganesha template in ceph-ansible via a ganesha jinja template [1]. Customers would like to update client related configuration in NFS_CORE_PARAM and metadata caching related options within MDCACHE blocks based on the kind of workloads they wish to run. 

It would be more flexible if ceph-ansible would allow overriding these values or provide a way to point to an alternative jinja template file [2] that could be used during deployment.
