Description of problem:
With the default nfs-utils configuration on Fedora 19,
a mount takes 15 sec delay.
This may be a simple configuration issue but I didn't find any relevant
documentation. The problem is present also on Rawhide.
Version-Release number of selected component (if applicable):
nfs-utils-1.2.8-3.0.fc19.i686
kernel-PAE-3.10.9-200.fc19.i686
systemd-204-9.fc19.i686
How reproducible:
Steps to Reproduce:
1. yum -y remove nfs-utils; yum -y install nfs-utils
2. systemctl stop firewalld.service&& setenforce 0
3. echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6
4. echo 1 > /proc/sys/net/ipv6/conf/default/disable_ipv6
5. echo "/opt localhost(rw)" > /etc/exports
6. exportfs -rav
7. mkdir /root/opt
8. time mount -vt nfs localhost:/opt /root/opt -overs=4
Actual results:
mount.nfs: timeout set for Tue Aug 27 XX:XX:XX 2013
mount.nfs: trying text-based options
'vers=4,addr=127.0.0.1,clientaddr=127.0.0.1'
real0m15.021s
user0m0.002s
sys 0m0.008s
In /var/log/messages
kernel: RPC: AUTH_GSS upcall timed out.
kernel: Please check user daemon is running.
Expected results:
mounts way below 1 sec.
Additional info:
The problem reported at
https://ask.fedoraproject.org/question/30612/nfs-gss-problems-on-f19/
Possible workarounds:
1. start rpc.gssd on the client:
systemctl enable nfs-secure.service
systemctl start nfs-secure.service
This results with "rpc.gssd: ERROR:
gssd_refresh_krb5_machine_credential: no usable keytab entry found in
keytab ..." in /var/log/messages
2. use -overs=3 when mounting from the client
3. blacklist the rpcsec_gss_krb5 module on the client:
echo "blacklist rpcsec_gss_krb5" > /usr/lib/modprobe.d/dist-blacklist.conf
reboot

You should use /etc/modprobe.d/ for custom configurations:
