I installed NFSv4 according to this wiki entry. https://wiki.archlinux.org/index.php/NFSv4
when i try to start the nfs-common daemon, here is what happens.
$this->bbcode_second_pass_code('', '[seth@alarm ~]$ sudo /etc/rc.d/nfs-common start
:: Starting rpc.statd daemon [DONE]
:: Mounting pipefs filesystem [BUSY] FATAL: Error inserting nfsd (/lib/modules/2.6.31.6_SMP_820/kernel/fs/nfsd/nfsd.ko.gz): Unknown symbol in module, or unknown parameter (see dmesg)
[DONE]
:: Starting rpc.idmapd daemon [DONE]')
There was a similar issue reported here. viewtopic.php?f=7&t=1363&p=7706&hilit=nfsd.ko.gz#p7706
I did try to reboot but that does not seem to resolve the issue.
