[Ubuntu] Check and format existing hdd/partition via command line
I want to add new hdd into my existing server, here is how to add it and make the partition and format it to ext4 filesystem.
First check the drive
Check the drive location:
sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL
would show the following:
NAME FSTYPE SIZE MOUNTPOINT LABEL
sda 111.8G
|-sda1 ext4 95.9G /
|-sda2 1K
|-sda5 swap 15.9G [SWAP]
sdb 465.8G
|-sdb1 ntfs 465.8G
In my case sdb is new added drive.
Prepare the drive
Using fdisk command:
sudo fdisk /dev/sdb
Now create a new partition, type:
n
Choose partition type (p for primary), type:
p
Enter the partition number.
1
It will ask you to set the start and end cylinders on the disk. Just hit enter for each to accept the defaults. Change the system type to Linux, type:
t
and
83
Write the changes to new disk.
w
Format to ext4
Format the new drive into ext4 filesystem.
sudo mkfs.ext4 /dev/sdb1
Mount the drive
Now the new partition has been created, you need to mount it somewhere to use it. Here I’m using /mnt/data/. First create the directory:
sudo mkdir /mnt/data/
and mount it into that directory:
sudo mount /dev/sdb1 /mnt/data/
Mounting the new drive automatically at booting
If you wish to mount the filesystem automatically each time the server boots, adjust the /etc/fstab file:
sudo nano /etc/fstab
Add below configuration to the last line.
/dev/sdb1 /mnt/data ext4 defaults 0 2
End.
