We noticed that all the files were owned by nobody

Here are my notes for dealing with this issue:

If all users come up as nobody on a nfs mount:

Add nfs server name to the Domain = line in /etc/idmapd.conf on both the server and the clients, i.e. Domain = nameof.server

/sbin/service rpcidmapd restart /sbin/service nfslock restart /sbin/service nfs restart

Also, the complete hostname as specified (nameof.server) must be in /etc/hosts on the nfs clients as well as the server

--------------- try /usr/sbin/nfsidmap -c on the client. Since I put this into my /etc/rc.local , I don't have the problem any longer. --------------- 1) /etc/idmapd.conf # Set domain to the domain name shared by your NFS servers. Domain: mycompany.com Set local-realms to the name of the nfs servers you'll be using. THIS WASN'T MENTIONED ELSEWHERE. Local-Realms: nfs1.mycompany.com,nfs2.mycompany.com # make the above changes on all the servers in question.

2) /etc/hosts: list with all the NFS servers you specified in local-realms above. This way DNS errors don't make your servers get hung 1.2.3.4 nfs1.mycompany.com 1.2.3.5 nfs2.mycompany.com

3) Make sure you synchronize your /etc/passwd files so that the account IDs match up or you'll get very strange results.

4) Reboot EVERYTHING. Restarting services was not enough. For documentation's sake, I restarted rpcidmapd, nfslock, and nfs, but didn't get the correct permissions until reboot. It doesn't seem important to run the nfs service on the clients.

5) Client mount: # CLI /bin/mount -t nfs servername:/path/to/share /local/mount/point

# /etc/fstab servername.com:/path/to/share /local/mount/mount nfs ro,nolock 0 0

# mount -a
