Update to this I found that you cannot create a 2nd files system as yet and it is still experimental. So I went down this route:
Added a pool to the existing cephfs and then setfattr -n ceph.dir.layout.pool -v SSD-NFS /mnt/cephfs/ssdnfs/ from a ceph-fuse client.
I then nfs mounted from another box. I can see the files and dir etc from the nfs client but my issue now is that I do not have permission to write, create dir etc. The same goes for the default setup after running the ansible playbook even when setting export to no_root_squash. I am missing a chain of permission? ganesha-nfs is using admin userid, is this the same as the client.admin or is this a user I need to create? Any info appreciated.
Ceph is on CentOS 7 and SELinux is currently off as well.
Copy of the ganesha conf below. Is secType correct or is it missing something?
RADOS_URLS {
ceph_conf = '/etc/ceph/ceph.conf';
userid = "admin";
}
%url rados://cephfs_data/ganesha-export-index
NFSv4 {
RecoveryBackend = 'rados_kv';
}
RADOS_KV {
ceph_conf = '/etc/ceph/ceph.conf';
userid = "admin";
pool = "cephfs_data";
}
EXPORT
{
Export_id=20133;
Path = "/";
Pseudo = /cephfile;
Access_Type = RW;
Protocols = 3,4;
Transports = TCP;
SecType = sys,krb5,krb5i,krb5p;
Squash = Root_Squash;
Attr_Expiration_Time = 0;
FSAL {
Name = CEPH;
User_Id = "admin";
}
}

Hi
I am using ceph-ansible to deploy and just looking for best way/tips on
how to export multiple pools/fs.
Ceph: nautilus (14.2.2)
NFS-Ganesha v 2.8
ceph-ansible stable 4.0
I have 3 x osd/NFS gateways running and NFS on the dashboard can see
them in the cluster. I have managed to export for cephfs / and mounted
it on another box.
1) can I add a new pool/fs to the export under that same NFS gateway
cluster, or
2) do I have the to do something like add a new pool to the fs and then
setfattr to make the layout /newfs_dir point to /new_pool? does this
cause issues and false object count?
3) any other better ways...
