Hi
Things that control nfs on the server are
1. /etc/sysconfig/nfs no modifications required for me
2. /etc/exports see mine below
3. firewall settings mine is off
4. /etc/idmapd.conf if using nfs4 - an nfs4 domain is required
5. /etc/fstab probably bind mounts needed - if using nfs4
First decision is whether to use nfs4 or not - this exports works for both on mine
The mount command on the client is different in the two case
nfs4
mount -t nfs4 maui:/global /global
nfs3
mount maui:/exports/global /global
---------------------------------------------------
maui.jaa.org.uk sysconfig 3# cat /etc/exports
/exports 148.197.29.0/24(rw,insecure,sync,wdelay,no_subtree_check,no_root_squash,fsid=0)
/exports/global 148.197.29.0/24(rw,insecure,sync,wdelay,no_subtree_check,nohide,no_root_squash)
/exports/home 148.197.29.0/24(rw,insecure,sync,wdelay,no_subtree_check,nohide,no_root_squash)
---------------------------------------------------
bind mounts for nfs4
maui.jaa.org.uk sysconfig 4# cat /etc/fstab
LABEL=home_maui /home ext3 defaults 1 2
LABEL=global_maui /global ext3 defaults 1 2
/home /exports/home none bind 0 0
/global /exports/global none bind 0 0
---------------------------------------------------
maui.jaa.org.uk sysconfig 5# cat /etc/idmapd.conf
[General]
Verbosity = 0
Pipefs-Directory = /var/lib/nfs/rpc_pipefs
#Domain = localdomain
Domain = jaa.org.uk
[Mapping]
Nobody-User = nfsnobody
Nobody-Group = nfsnobody
[Translation]
Method = nsswitch
---------------------------------------------------
maui.jaa.org.uk sysconfig 6# ps -ef|grep -i rpc
root 2380 1 0 Jul02 ? 00:00:00 rpc.idmapd
---------------------------------------------------
[root@maui ~]# service rpcidmapd status
rpc.idmapd (pid 2380) is running...
---------------------------------------------------
On the client (F11 in my case)
The default /etc/idmapd.conf should work if the nfs4 domain is the same
as the DNS domain - if in doubt force them to be the same on both the server and the client
The nfsnobody ownership is probably the result of the server and client domain not being the same
(and/or idmapd not running on both server and client)
/etc/idmapd.conf
naxos ~ 1# cat /etc/idmapd.conf
[General]
#Verbosity = 0
# The following should be set to the local NFSv4 domain name
# The default is the host's DNS domain name.
#Domain = local.domain.edu
Domain = jaa.org.uk
...
Hope this helps
John
