SELinux is preventing /usr/bin/mount from mounton access on the directory /proc/fs/nfsd.
***** Plugin catchall (100. confidence) suggests ***************************
If you believe that mount should be allowed mounton access on the nfsd directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep mount /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
