I am going to put an additional (non-USB) hard drive in my system. I already have Ubuntu on my other hard drive so I do not want to install Ubuntu on the additional drive but only use it for storage. How do I add the additional hard drive to my Ubuntu system, e.g. make Ubuntu recognize it and mount it properly?
The easiest and user-friendly way is probably to use
gparted after you have installed your new HDD and boot your machine:
Then you create partitions, by setting their size and type.
Hint: since your hard drive is additional storage space, you probably want to create one single big partition with the type of
gparted is a very easy to use tool, and yet very advanced.
After you are done creating your partitions (most likely it will be just one
ext4 data partition, since this is your additional storage drive), you need to permanently mount it.
At this step you already know what names your new partition(-s) have. If not sure, following command will remind you about existing drives and partitions on them:
sudo fdisk -l
This will output something like this (intentionally skipped
/dev/sda system drive info):
Disk /dev/sda: 250.1 GB, 250059350016 bytes .... Disk /dev/sdb: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x000814e3 Device Boot Start End Blocks Id Syste /dev/sdb1 1 243201 1953512001 83 Linux
Output states, that your new partition is
/dev/sdb1. Now you need to mount it to utilize it's precious space. To achieve this, you need to perform three simple steps:
2.1 Create a mount point
sudo mkdir /hdd
2.2 Edit /etc/fstab
/etc/fstab file with
sudo vim /etc/fstab
And add following to the end of the file:
/dev/sdb1 /hdd ext4 defaults 0 0
2.3 Mount partition
Last step and you're done!
sudo mount /hdd
Modern drives are huge and need to be partitioned with GPT to allow 2TB+ in size.
Find your disk:
If it is already formatted, you should see entry like
If your disk is not formatted, create a new partition:
and format it:
mkfs -t ext4 /dev/sdb1
Create directory for your hdd:
/dev/sdb1partition and add it into
/etc/fstab(make backup of
etckeeper- this file is important):
UUID="b4c93..." /media/storage ext4 defaults 0 2
fstab wiki page describes what does it mean. This should make it persistent over reboots.
Finally mount it without rebooting to test:
There is a good description how to add another drive here:
Basically you have to partition the new disk, create a file system on it and then mount it. Thats is the easy way. Another way would be to use lvm and create virtual disks on the new drive. That would give you more flexibility:
First you need to identified the new hard disk.
T to open a console then type :
You will see something similar with this:
loop0 7:0 0 86.6M 1 loop /snap/core/4486 sda 8:0 0 5G 0 disk ├─sda1 8:1 0 512M 0 part /boot/efi └─sda2 8:2 0 4.5G 0 part / sdb 8:16 0 10G 0 disk sr0 11:0 1 1024M 0 rom
For example the sdb it's the new hard disk that you want to add.
If the sdb it's a new hard disk , you need to format to ext3 or ext4
sudo mkfs.ext4 -j -L NewHDD /dev/sdb
Keep in mind, command above will delete everything on target hard disk. You can skip this step if there are any data on the hard disk and you want to not lose them.
Now you need the UUID of the new hard disk.
sudo blkid /dev/sdb
You will see something similar with this:
/dev/sdb: LABEL="NewHDD" UUID="5d6c8f68-dcc8-4a91-a510-9bca2aa71521" TYPE="ext4"
next step it's to add the new hard disk in fstab for auto mount after reset:
sudo nano /etc/fstab
And add new line on bottom, with follow content:
/dev/disk/by-uuid/5d6c8f68-dcc8-4a91-a510-9bca2aa71521 /mnt/NewHDD auto nosuid,nodev,nofail,x-gvfs-show,x-gvfs-name=NewHDD 0 0
Remeber to replace the
/mnt/NewHDD whit your own UUID and path where will be mounted,
X then press
ENTER to save it.
To mount it use:
sudo mount -a , if the result will be:
mount: /mnt/NewHDD: mount point does not exist.
You must create mount point
sudo mkdir /mnt/NewHDD then use again:
sudo mount -a
Also you need to change owner and group of the new hard disk using next command:
sudo chown user:user -R /mnt/NewHDD
user:user with your own user and group that you need it.
