-====== NFS Shares ======
-**General Information**
-Creating NFS shares on a server and connecting to them via a client.
-**Checklist**
-  * Distro(s): Enterprise Linux 7
-  * Other: Two systems (server and client)
-----
-====== NFS Server Setup ======
-  * Install required package<code bash>yum install nfs-utils</code>
-  * Start and enable the NFS Server<code bash>systemctl start nfs-server
-systemctl enable nfs-server</code>
-  * Create your share directory structure<code bash>mkdir -p /data/share1</code>
-  * Create an export line to share the directory<code bash>vim /etc/exports
-/data/share1  192.168.1.0/24(rw)</code>
-    * /data/share1 => the directory to share
-    * 192.168.1.0/24(rw) => share to entire network with read/write.
-      * Other ways to share are to specify single hostnames(short, fqdn, single ip), IP networks (as shown), hostnames/domains with wildcards (*.mydomain.edu). See man exports for more details.
-  * If a firewall is running, allow nfs, rpc-bind, and mountd<code bash>firewall-cmd --permanent --add-service=nfs
-firewall-cmd --permanent --add-service=rpc-bind
-firewall-cmd --permanent --add-service=mountd
-firewall-cmd --reload</code>
-    * nfs (tcp/udp 2049) => needed for NFSv4
-    * rpc-bind (tcp/udp 111) => needed for NFSv3 compatibility and for showmount to work from client
-    * mountd (tcp/udp 20048) => needed for the "showmount -e hostname" command to work from a client
-----
-===== NFS Server: Increasing NFS Threads =====
-To increase NFS server performance, it is usually necessary to increase the number of NFS daemon processes running. (The default is very small at 8.)
-  * CentOS 7
-    * Edit the following config file<code bash>vim /etc/sysconfig/nfs
-# Number of nfs server processes to be started.
-# The default is 8.
-RPCNFSDCOUNT=16
-</code>
-    * Restart the nfs-config service<code bash>systemctl restart nfs-config</code>
-    * Restart the nfs service<code bash>systemctl restart nfs-server</code>
-    * Verify
-      * NFS running sysconfig (takes effect after nfs-config restart)<code bash>cat /run/sysconfig/nfs-utils
-RPCNFSDARGS=" 16"</code>
-      * "th" line in proc (number after 'th' is number of processes)<code bash>grep th /proc/net/rpc/nfsd
-th 16 0 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000</code>
-      * Running processes<code bash>ps -elf | grep nfsd] | grep -v grep | wc -l
-</code>
-----
-====== NFS Client Setup ======
-  * Install required package<code bash>yum install nfs-utils</code>
-  * View available mounts on NFS Server<code bash>showmount -e fileserver01
-Export list for fileserver01:
-/data/share1 192.168.1.0/24</code>
-  * Mount temporarily<code bash>mount -t nfs fileserver01:/data/share1 /mnt</code>
-  * Mount persistently<code bash>vim /etc/fstab
-## NFS Shares ##
-fileserver01:/data/share1  /remote  nfs  _netdev  0 0</code>
-    * _netdev => Mount option to skip mounting this location until the network is available.
