It sounds like you're putting the FSAL_CEPH config in another file in
/etc/ganesha. Ganesha only loads one file: /etc/ganesha/ganesha.conf -
other files need to be included in that file with the %include command.
For a simple config like yours, just use the single
/etc/ganesha/ganesha.conf file.

Hello Amudhan,
The only ceph specific thing required in the ganesha config is to add the
FSAL block to your export, everything else is standard ganesha config as
far as I know. eg: this would export the root dir of your cephfs as
nfs-server:/cephfs
EXPORT
{
Export_ID = 100;
Path = /;
Pseudo = /cephfs;
FSAL {
Name = CEPH;
User_Id = cephfs_cephx_user;
}
CLIENT {
Clients = 1.2.3.4;
Access_type = RW;
}
}
This will rely on ceph config in /etc/ceph/ceph.conf containing typical
cluster client connection info (cluster id, mon addresses etc).
You also have to have the cephx user specified configured for cephfs
access, including the keyring file in
/etc/ceph/ceph.client.cephfs_cephx_user.keyring.
Your cephx user could be the same one you use to mount the FS using kernel
client, but you will need the keyring file in place, and the ceph.conf.
Not sure how many changes have been made to config since ganesha 2.6, but
the 2.6 version of the sample is here:
https://github.com/nfs-ganesha/nfs-ganesha/blob/V2.6-stable/src/config_samples/ceph.conf
You should be able to see if there were any issues loading configuration
params or the ceph fsal in the ganesha log, typically /var/log/ganesha.log
or /var/log/ganesha/ganesha.log.

Hi,
I am trying to setup NFS ganesh in Ceph Nautilus.
In a ubuntu 18.04 system i have installed nfs-ganesha (v2.6) and
nfs-ganesha-ceph pkg and followed the steps in the link
https://docs.ceph.com/docs/nautilus/cephfs/nfs/ but i am not able to
export my cephfs volume there is no error msg in nfs-ganesha, also i doubt
whether its loading nfs-ganesha-ceph config file from "/etc/ganesha"
folder.
From same system i am able to mount thru ceph kernel client without any
issue?
How do i make this work?
regards
Amudhan
