Thanks for the work-around on the warning, I had updated the kernel by the time I saw your message, since I was watching closely for updates. Good to hear. I didn't bother to fix the error. Only thing which I hated was that I thought first (like you did) that this error was caused by the failure of nfs-mount. But after little bit of searching around I found out it was unrelated. Then I actually managed to find the root cause. I actually thought of upgrading to CentOS6 for a while because of that. One thing I learned from this is that one can't trust even RH to actually test the core features of the releases in automated way. And that I am really happy to have a test server as it really (even as a virtual machine) saves you from sleepless nights. :) -vpk -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

NFS mount fails CentOS5 on FC16 host
I get a message rpc.idmapd appears not to be running when it is running, and I'm using the same setup I have on my other clients from FC9 to fc17, including both 32/64 bit RHEL. Checked DNS to be sure the IP reverse maps properly, etc, etc. I do this on a real bunch of other machines, so I'm reasonably sure it's set up correctly. I did diff idmapd config between working and non-working machines, etc. Everything maps to nobody, which is not useful. Both CentOS5 and FC16 machines are current on patches. mount is rw,soft,intr -t nfs4 and the idmap process is running on host and client, remounts from other clients work, etc, etc. Anyone have a clue? -- Bill Davidsendavid...@tmr.com We are not out of the woods yet, but we know the direction and have taken the first step.

Re: NFS mount fails CentOS5 on FC16 host
it would be nice and useful if you can show /etc/sysconfig/iptables, /etc/sysconfig/nfs from both machines and showmount -e $server from client side and exports from server side.
