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 --------------------------------------------------- [r...@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 ...
