When attempting to clear NFS uid/gid cache I ran nfsidmap -c
no response, nfsidmap does not return anything if it completes properly
[root@quebec ~]# nfsidmap -c
What did happen
root@u1404vm:~# nfsidmap -c
nfsidmap: fopen(/proc/keys) failed: No such file or directory
I checked /proc and the /proc/key-users file and the
/proc/sys/kernel/keys directory were there.
I Looked up Kernel Key Management and saw that /proc/keys was needed to
hold the key pairs used by the kernel.
From Google'ng the following kernel option needs to be enabled
or /proc/keys does not get created.
I checked /boot/config-3.13.0-24-generic and that option is not enabled.
I checked this on both Centos 6.5/7 and Mageia and they are enabled and
/proc/keys exist, nfsidmap -c works.
