Thank you Paul. mount_path_pseudo does the trick.
Now nfs v3 works on Linux, but on MAC OS, it mounts successfully, with
empty folder:
bat8485maci:~ root# mount -t nfs -o vers=3 ceph-admin:/ceph /mnt/ceph
bat8485maci:~ root# ls -l /mnt/ceph/
bat8485maci:~ root#
This is how it looks like on Linux:
root@yyang-deb9-64:~# mount -t nfs ceph-admin:/ceph /mnt/ceph
mount.nfs: requested NFS version or transport protocol is not supported
root@yyang-deb9-64:~# mount -t nfs -o vers=3 ceph-admin:/ceph /mnt/ceph
root@yyang-deb9-64:~# ls -l /mnt/ceph/
total 2
drwxr-xr-x 3 root root 8566720930 Jun 27 08:32 Btnas1_stage
drwxr-xr-x 3 root root 2776623737 Jun 27 08:37 Btnas2_stage
drwxr-xr-x 6 batserve users 456266 Jun 25 21:30 include
drwxrwxrwx 2 root root 0 Jun 27 08:32 scratch
Is this a MAC OS nfs bug? or an nfs-ganesha issue? By the way,
my /etc/ganesha/ganesha.conf is as below:
EXPORT_DEFAULTS
{
SecType = sys;
Protocols = 3;
}
NFS_CORE_PARAM
{
Enable_NLM = false;
Enable_RQUOTA = false;
Protocols = 3;
mount_path_pseudo = true;
}
CACHEINODE {
Dir_Chunk = 0;
NParts = 1;
Cache_Size = 1;
}
EXPORT
{
Export_ID=100;
Protocols = 3;
Transports = TCP,UDP;
Path = /;
Pseudo = /ceph;
Tag = ceph;
Access_Type = RW;
Attr_Expiration_Time = 0;
Squash = None;
FSAL {
Name = CEPH;
}
}
Thanks,
--Youzhong
