Mount a new drive in CentOS after Restart

Like windows, we can format and make a new drive available for use by using the following simple steps
Step 1:
It is needed to verify whether the new drive is visible in the system. Using fdisk command, it can be identified.
fdisk -l
It will list all drives available in the system including mounted and unmounted drives. Here assume a new drive label is /dev/ssd
Step 2:
It is needed to create the file system ext4(in shortly say as formatting drive). So make sure drive is fresh/empty one. It a drive has already data, don’t enter this step, instead skip to next step. The following command helps to create file system
mkfs -t ext4 /dev/ssd
Step 3:
Now create a new directory in the root(or in desired path) to mount a formatted drive using mkdir command
mkdir mntssd
Step 4:
To mount the formatted drive with newly created directory, use the mount command
mount /dev/ssd mntssd
Now drive is available for use under mntssd directory
Step 5:Actually mounted drive will not be available once rebooted. To avoid this loss, it is needed to set mounted drive details on fstab config file. The following commands will help to setup the settings
1. cp /etc/fstab /etc/fstab.orig  (**backup the config file before change to avoid loss of original settings if any)
2. vi /etc/fstab
3. Add this line at the end: /dev/ssd    /mntssd        ext4    defaults    0 2
4. Save the file and exit the editor
5. Use “mount -a” command to verify the fstab settings added correctly. If any error, correct the fstab settings according to the error generated
That’s all!
