This mount is temporary , once server is rebooted it will go off.
To make it permanent ,follow below steps.
run the blkid command to get the UUID value of the new FS
============================================================
# blkid /dev/mapper/VolGroupSys-optNWLV1
/dev/mapper/VolGroupSys-optNWLV1: LABEL="optNWLV1" UUID="9c79364e-99e1-42a8-ada1-86c31ad1fa76" TYPE="ext4"
Note : Add the above entry in /etc/fstab.
So take backup of /etc/fstab before edit the file.
