I have clients accessing CephFS over nfs (kernel nfs). I was seeing slow writes with sync exports. I haven't had a chance to investigate and in the meantime I'm exporting with async (not recommended, but acceptable in my environment).
I've been meaning to test out Ganesha for a while now
@Sean, have you used Ganesha with Ceph? How does performance compare with kernel nfs?

Hi,
One of the use-cases I'm currently testing is the possibility to replace
a NFS storage cluster using a Ceph cluster.
The idea I have is to use a server as an intermediate gateway. On the
client side it will expose a NFS share and on the Ceph side it will
mount the CephFS using mount.ceph. The whole network that holds the Ceph
environment is 10G connected and when I use the same server as S3
gateway I can store files rather quickly. When I use the same server as
a NFS gateway putting data on the Ceph cluster is really very slow.
The reason we want to do this is that we want to create a dedicated Ceph
storage network and have all clients that need some data access either
use S3 or NFS to access the data. I want to do this this way because I
don't want to give the clients in some specific networks full access to
the Ceph filesystem.
Has anyone tried this before? Is this the way to go, or are there better
ways to fix this?
