If you have a new drive you want to add to your system, it's not going to work right out of the box. It needs to be correctly formatted a partition table and a linux-friendly filesystem.

On a CentOS 7 server, I am

Create a new disk label:
[bwong1@band Desktop]$ sudo parted /dev/sdb mklabel gpt
Information: You may need to update /etc/fstab.

Create a single partition using optimal settings that utilizes all free space
[bwong1@band Desktop]$ sudo parted -a optimal /dev/sdb mkpart primary 0% 100%
Information: You may need to update /etc/fstab.

Make sure config is right so far by printing it:
[bwong1@band Desktop]$ sudo parted -a optimal /dev/sdb mkpart primary 0% 100%
[bwong1@band Desktop]$ sudo parted /dev/sdb print
Model: ST8000DM 0004-1ZC11G (scsi)
Disk /dev/sdb: 8002GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 1049kB 8002GB 8002GB primary

Write a filesystem to the newly created disk partition:
[bwong1@band Desktop]$ sudo mkfs -t xfs /dev/sdb1
meta-data=/dev/sdb1 isize=256 agcount=8, agsize=268435455 blks
= sectsz=512 attr=2, projid32bit=0
data = bsize=4096 blocks=1953506304, imaxpct=5
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal log bsize=4096 blocks=521728, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0

Mount the new filesystem identified by diskid partition to a place of your choice. I mount it to /mnt/usb because I'm using a usb attached HDD.
[bwong1@band Desktop]$ sudo mount /dev/sdb1 /mnt/usb
[bwong1@band Desktop]$ df -hl /mnt/usb/
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 7.3T 33M 7.3T 1% /mnt/usb
