>Summary
>    SELinux is preventing /usr/sbin/rpc.mountd (nfsd_t) "ioctl" to
>    /dev/mapper/control (lvm_control_t).
>
>Detailed Description
>    SELinux denied access requested by /usr/sbin/rpc.mountd. It is not expected
>    that this access is required by /usr/sbin/rpc.mountd and this access may
>    signal an intrusion attempt. It is also possible that the specific version
>    or configuration of the application is causing it to require additional
>    access.
>
>Allowing Access
>    Sometimes labeling problems can cause SELinux denials.  You could try to
>    restore the default system file context for /dev/mapper/control, restorecon
>    -v /dev/mapper/control If this does not work, there is currently no
>    automatic way to allow this access. Instead,  you can generate a local
>    policy module to allow this access - see http://fedora.redhat.com/docs
>    /selinux-faq-fc5/#id2961385 Or you can disable SELinux protection
>    altogether. Disabling SELinux protection is not recommended. Please file a
>    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.
