B)add the mount point:
As root user:
1. create a mount point for the data partition:
sudo mkdir /mnt/DATA
B)add the mount point:
As root user:
1. create a mount point for the data partition:
sudo mkdir /mnt/DATA
2.This command will format the partition with ext4 FS
mkfs.ext4 /dev/sdc1
mkfs.ext4 /dev/sdc1
3.Mount the partition:
sudo mount /dev/sdb1 /mnt/DATA
sudo mount /dev/sdc1 /mnt/ARCHIVE
sudo mount /dev/sdd1 /mnt/BACKUP
(OR)
mount -t auto /dev/sdc1 /mnt/DATA4.Take ownership of the mount point:
sudo mount /dev/sdb1 /mnt/DATA
sudo mount /dev/sdc1 /mnt/ARCHIVE
sudo mount /dev/sdd1 /mnt/BACKUP
(OR)
mount -t auto /dev/sdc1 /mnt/DATA4.Take ownership of the mount point:
sudo chown -R postgres: /mnt/DATA
sudo chown -R postgres: /mnt/ARCHIVE
sudo chown -R postgres: /mnt/BACKUP
sudo chown -R postgres: /mnt/ARCHIVE
sudo chown -R postgres: /mnt/BACKUP
5.Find out the UUID# for your data partition:
[root@localhost ]# sudo blkid/dev/sda1: UUID="15fe408e-72ef-47fe-b3f0-e33f032c1d9f" TYPE="xfs" /dev/sda2: UUID="03a8e0e8-ae89-4a1f-bafc-c03826de7ea5" TYPE="swap" /dev/sda3: UUID="f45ae60c-162f-4da2-aa33-f76723e0c5fe" TYPE="xfs" /dev/sdb1: UUID="46c3be28-2646-495e-9d1b-5f9be9d1e154" TYPE="ext4" /dev/sdc1: UUID="c5abf63e-a9ad-410c-a685-4407d9a12b93" TYPE="ext4" /dev/sdd1: UUID="961e84b2-dbe2-4f2c-ade7-72c2b2b5289d" TYPE="ext4" /dev/sr0: UUID="2016-08-17-06-07-50-00" LABEL="RHEL-7.3 Server.x86_64" TYPE="iso9660" PTTYPE="dos"6.Open your fstab file and make an entry to auto-mount the data partition on boot:
gksu gedit /etc/fstab (OR) vi /etc/fstab
(Note: you may need to substitute a different text editor if gedit not installed to your version of Mint.)
gksu gedit /etc/fstab (OR) vi /etc/fstab
(Note: you may need to substitute a different text editor if gedit not installed to your version of Mint.)
In gedit, add either of the two examples below (substitute your UUID# for the ones listed here):
A.For an Ext4 formatted partition, add these two lines to end of fstab file:
A.For an Ext4 formatted partition, add these two lines to end of fstab file:

# Mount DATA partition under /DATAUUID=747D4C9C1EFAD1F2 /mnt/DATA ntfs-3g defaults,windows_names,locale=en_US.utf8 0 0Save the changes to fstab and close the text editor or vim editor
