Second way to create FS is directly using the physical partition. Of course the drawback of this method is that you have you use the entire physical partition, rather than the logical partition.
[root@auxserver ~]# fdisk -l Disk /dev/sda: 8589 MB, 8589934592 bytes, 16777216 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x000cd5a4 Device Boot Start End Blocks Id System /dev/sda1 * 2048 2099199 1048576 83 Linux /dev/sda2 2099200 16777215 7339008 8e Linux LVM Disk /dev/sdb: 8589 MB, 8589934592 bytes, 16777216 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes
[root@auxserver ~]# fdisk /dev/sdb
Welcome to fdisk (util-linux 2.23.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Edit the /etc/fstab to add new configuration:
[root@auxserver ~]# tail -100f /etc/fstab # # /etc/fstab # Created by anaconda on Mon Jan 15 05:54:00 2018 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/centos-root / xfs defaults 0 0 UUID=9350c1d9-7aa7-4267-a4e7-1607ef9e1465 /boot xfs defaults 0 0 /dev/mapper/centos-swap swap swap defaults 0 0 /dev/sdb1 /newFS ext4 defaults 0 0
Mount the FS if it isn't already mounted:
[root@auxserver ~]# mount /newFS
mount: /dev/sdb1 is already mounted or /newFS busy
/dev/sdb1 is already mounted on /newFS
[root@auxserver ~]#
