How to format a new disk using command? [duplicate]

  • 772

I am new to Ubuntu and have a quesion:

I have Ubuntu 16.04 running on VMware. My initial setup had one disk. I added another 2 disk (one 2GB and one 1GB). Now I want to add them to the Ubuntu, how can I do that? First I know I should format them but when I want run fdisk command I get this error:

Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0xd5a1dff9.

Command (m for help):

And here is my disk info:

  *-disk:0                
       description: SCSI Disk
       physical id: 0.0.0
       bus info: scsi@32:0.0.0
       logical name: /dev/sda
       size: 10GiB (10GB)
       capabilities: partitioned partitioned:dos
       configuration: logicalsectorsize=512 sectorsize=512 signature=bcc12dac
  *-disk:1
       description: SCSI Disk
       physical id: 0.1.0
       bus info: scsi@32:0.1.0
       logical name: /dev/sdb
       size: 1GiB (1073MB)
       configuration: logicalsectorsize=512 sectorsize=512
  *-disk:2
       description: SCSI Disk
       physical id: 0.2.0
       bus info: scsi@32:0.2.0
       logical name: /dev/sdc
       size: 2GiB (2147MB)
       configuration: logicalsectorsize=512 sectorsize=512

       physical id: 0.0.0
       bus info: scsi@3:0.0.0
       logical name: /dev/cdrom
       logical name: /dev/cdrw
       logical name: /dev/dvd
       logical name: /dev/sr0
       capabilities: audio cd-r cd-rw dvd dvd-r dvd-ram
       configuration: status=open

My question is how to solve this issue using command only?

format partitioning fdisk

    1.format /dev/sdb

    fdisk /dev/sdb
enter: n
enter: p ( primary )
enter: default -> press enter
enter: default-> press enter

enter:w ( write ) to save the changes 

if you type fdisk -l : you should see a /dev/sdb1

    Now make a ext4 filesystem on it with: mkfs.ext4 /dev/sdb1 Create the domain you wish to mount it like /db with mkdir /db Mount it: mount /dev/sbd1 /db To mount after reboot you need to add this in the fstab similar to / You need to get the UID of the partition with: blkid These UID you need to add in the new line you have added in /etc/fstab.

    For the second disk you do it in the same way
