Mount a new drive in CentOS

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

Tăng/mở rộng (Increase/expand) ổ đĩa hệ thống tệp XFS trong RHEL7 / CentOS 7

Bài này hướng dẫn tăng/mở rộng ổ đĩa hệ thống XFS trên máy máy ảo (Vmware Vitual Machine) mà không cần phải khởi động lại máy chủ.
Để kiểm tra máy chủ của bạn có những tệp tin định nghĩa ổ cứng XFS dùng lệnh “df -hT”. Bạn chú ý ở côt “Type” có “xfs”:

[adminvpbs@ho-demops1 ~]$ df -hT
