I am trying to get a basic nfs4 working between two machines (let's call them server and client). I have followed this manual by letter to no avail. Here's what I'm getting:
root@server#: tail -n 2 /etc/exports
/export client-ip/24(rw,nohide,insecure,no_subtree_check,async,no_root_squash)
/export/users client-ip/24(rw,nohide,insecure,no_subtree_check,async,no_root_squash)
root@server#: showmount --exports
Export list for server-ip:
/export/users client-ip/24
/export client-ip/24
Server side seems to be OK. Directories exist, their permissions are granted (775). Addresses (client-ip and server-ip) are numeric - replaced with acronyms here for obvious reasons. Next, the client:
root@client#: mount -v -t nfs4 server-ip:/export /opt/nfstest
mount.nfs4: timeout set for Thu Apr 14 15:52:31 2011
mount.nfs4: text-based options: 'clientaddr=client-ip,addr=server-ip'
mount.nsf4: mount(2): No such file or directory
mount.nfs4: mounting server-ip:/export failed, reason given by server:
No such file or directory
It just doesn't accept the remote folder. Apart from one above, I tried server-ip:/export/users
, server-ip:/
- getting same result. Client does have access to server:
root@client#: telnet server-ip 2049
Trying server-ip...
Connected to server-ip.
Escape character is '^]'.
root@client#: showmount -e server-ip
Export list for server-ip:
/export/users client-ip/24
/export client-ip/24
Local directory /opt/nfstest
exists. Module nfs
is loaded on the nfs client. There are no firewall between the server and client. What else should I check?
Additional information: Ubuntu Lucid (10.04.2), running on Amazon ec2 box. NFS versions (nfs-common
, nfs-kernel-server
) are 1:1.2.0-4ubuntu4.1.
mount -v server-ip:/export /opt/nfstest
)?/etc/default/nfs-common
to haveNEED_IDMAPD=no
from=yes
(which probably downgraded nfs to v3). Can't change this back right now as the share is in active use - needed to get things working.
