[Bug 487373] New: idmapd needs nfsd module loaded
https://bugzilla.novell.com/show_bug.cgi?id=487373 Summary: idmapd needs nfsd module loaded Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: jnelson-suse@jamponi.net QAContact: qa@suse.de Found By: --- User-Agent: Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.9.0.7) Gecko/2009022800 SUSE/3.0.7-1.1.6 Firefox/3.0.7 I was having a bear of a time figuring out why *sometimes* user IDs and such were not mapping correctly for an NFSv4 mount. Some googling turned this up: https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/235930 sure enough, if I modprobe'd nfsd, killall -HUP rpc.idmapd (which I tried before), UIDs and such map correctly. Also, there should be a config option (/etc/sysconfig/nfs) to always start NFS *client services* even if there are no explicit mounts in /etc/fstab - there are many other ways of mounting NFS (incl. v4) than via /etc/fstab and if idmapd is not started NFSv4 doesn't work.

--- Comment #3 from Neil Brown
All I know is that when the nfsd module is not loaded, I get this when starting nfs services (when idmapd starts):
Mar 17 06:56:22 worklaptop rpc.idmapd[12653]: nfsdopenone: Opening /proc/net/rpc/nfs4.nametoid/channel failed: errno 2 (No such file or directory)
and when it is loaded, I don't get that.
That is completely expected. If nfsd module is not loaded, idmapd will not service requests from it. That should not affect how it services requests from the NFS client.
The weird UID mapping thing might be a red herring, and can be discounted for now until I get more concrete evidence of something wonky going on.
The wierd UID mapping is the only evidence that there is a problem, and it does seem to be a real problem. Any more concrete evidence that you can gather would be helpful.
