I've resolved this issue, in a way that both uses the server names
(instead of IP) but avoids DNS problems also and allows you to use
shares from multiple servers. Every instruction I read indicated that
the hostname value was important. Careful scrutinizing of the config
file reveals that there are really two values that are important, so
here's my rough instruction:
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 (in my case) 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 hume.schoolpathways.com:/path/to/share /local/mount/point
# /etc/fstab
nfs1.mycompany.com:/path/to/share /local/mount/mount nfs ro,nolock 0 0
# mount -a
