How to create /etc/exports for NFSv4?

[Canedje]

I don't understand how to configure for the new NFSv4?
In the exportsfile there is an example:

Code: Select all

# Example for NFSv4:
# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check)
#

My old exports did looks like:

Code: Select all

/home/ewh 192.168.2.0/24 (rw)

Please help to change my old export to the new standard

I just checked on my MINT-17 machine, and it seems to be using NFSV4 and my /etc/exports file looks like it always did (i.e. the V3 example )

Have you tried it ?

Yes. But not working I do have allready several days trouble mounting
Sometimes it works. Most off the times not
I re-installed severall times everything. Sometimes it works then, sometimes not.
If it works it is until a updat/upgrade

It makes me crazy

[PeterO]

How does it fail ? Anything in log files when it works or fails ?

Thats one off the problems.
There are not realy error files for mounting.

if I try to mount:
sudo mount -v -t nfs 192.168.2.202:/home/ewh /mnt/PI

Code: Select all

mount.nfs: timeout set for Sat Nov 19 12:49:29 2016
mount.nfs: trying text-based options 'vers=4,addr=192.168.2.202,clientaddr=192.168.2.185'
mount.nfs: mount(2): Connection refused

sudo exportfs at the other RPI shows:
sudo exportfs

Code: Select all

/home/ewh       192.168.2.202
/home/ewh       <world>

The nfs kernel is running
RPCbind is running

That all looks correct

EDIT:
It is running again.
It looks like something is wrong after update/upgrade with the nfs kernel
If I do:

Code: Select all

sudo /etc/init.d/nfs-kernel-server restart

The mount is working again
