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 -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com
