NFS Server won't update new host in netgroup

Issue

• I added a new IP address to /etc/netgroup, but the nfsd won't pick up the new NFS Client
• When mounting a directory inside another directory, an NFSv4 client may receive an -ENOENT error:

[root@nfs-client]# mount -t nfs4 -o rw nfs-server:/data/path/reports /mnt/reports
mount.nfs4: nfs-server:/data/path/reports failed, reason given by server: No such file or directory

• An NFS client may also receive an -EACCES error using both NFSv3 or NFSv4

[root@nfs-cli-6 ~]# mount -t nfs -o defaults,vers=3 nfs-srv-6:/data /mnt/data
mount.nfs: access denied by server while mounting nfs-srv-6:/data

[root@nfs-cli-6 ~]# mount -t nfs -o defaults,vers=4 nfs-srv-6:/data /mnt/data
mount.nfs: access denied by server while mounting nfs-srv-6:/data
