### This script mount an nfs hardisk located in server $ipnsf to the directory $nfs_dir in the current node running this script 

# Use this script only in a node but not in the frontend

# Check NFS Share
# Before mounting the NFS share directory in local node ('NFS client'), check the NFS shares available on the NFS server by running the following command on the NFS client.

ipnfs=192.168.1.22     #### this is the ip address of the NFS host where the external hardisk is sitting

showmount -e $ipnfs

# Mount the shared directory in the NFS clients. nfs_dir is the name of the shared directory in $ipnfs

nfs_dir=/state/partition1/ext_storage2

mkdir $nfs_dir

echo '$ipnfs':'$nfs_dir $nfs_dir'  $ipnfs':'$nfs_dir $nfs_dir

mount $ipnfs':'$nfs_dir $nfs_dir


##  customize permission of $nfs_dir

#chmod -R 775 $nfs_dir
#chown -R root:users $nfs_dir
echo 'see me?'

#Verify the mounted share on the NFS client using mount command.

#mount | grep nfs

#Also, you can use the df -hT command to check the mounted NFS share.

df -hT

#Create a file on the mounted directory to verify the read and write access on NFS share.

#touch $nfs_dir'/test_'$HOSTNAME

#If the above command returns no error, you have working NFS setup

# To mount the shares automatically on every reboot, you would need to modify /etc/fstab file of your NFS client.

cp /etc/fstab /etc/fstab.orig
echo $ipnfs':'$nfs_dir $nfs_dir ' nfs   nosuid,rw,sync,hard,intr  0  0' >> /etc/fstab

# Reload the entries in the modified /etc/fstab, by using the mount command:	
mount -av
