How to partition SSD+HDD?

rated 0 times [ 6] [ 0] / answers: 1 / hits: 6982 / 2 Years ago, sun, september 18, 2022, 1:21:40

I have installed Ubuntu 14.04 on 1TB HDD and have installed lots of packages and softwares. Now i've bought an 128GB SSD, I have few questions on how to partition SSD and HDD and how to move my current installation to SSD.

I'm thinking to have / and /home on SSD, and store other files on HDD, so how can i partition SSD+HDD to have:

/ and /home on SSD

have /home/music, /home/videos, /home/downloads, /home/pictures on HDD

I have no idea about swap partition (should it be on SSD or HDD, actually its empty most of the time now), my laptop has 16 GBs of RAM

I'm planning to have fresh install of 14.04 on SSD (and i think i have to), so what is the best way to move currently installed packages to new installation ? i'm planning to use Aptik for that, is there a better solution ?

Is preload any good and gives performance boost when using SSD (i have 16 GBs of RAM)

You have almost the same setup as me. 128 GB SSD 1.5 TB conventional.

Here is how I would do it:

Leave everything on the conventional drive for the time being.

Install and partition the ssd using a live distribution usb stick. I wouldn't even touch your old drive here.

See if everything boots to the new partition okay. You may need to adjust bios settings to make it boot to your new drive.

set up the mountpoint



sudo -i

mkdir /media/hdd

blkid

You will get something like the following:



/dev/sda1: UUID="0f6e1051-cf9f-4299-b691-76d0d8c532d1" TYPE="ext4" 

/dev/sda5: UUID="058b6235-7e74-42ce-96c9-59f6cb0a44f3" TYPE="swap" 

/dev/sdb1: UUID="40a50699-a900-4bfe-a9e4-6587c1a83464" TYPE="ext4"

copy the UUID of your secondary drive (mine is sdb1)

nano /etc/fstab

paste in uuid line without the quotes and add some fstab goodness:



# /etc/fstab: static file system information.

#

# Use 'blkid' to print the universally unique identifier for a

# device; this may be used with UUID= as a more robust way to name devices

# that works even if disks are added and removed. See fstab(5).

#

#                

# / was on /dev/sda1 during installation

UUID=0f6e1051-cf9f-4299-b691-76d0d8c532d1 /               ext4    errors=remount-ro 0       1

# swap was on /dev/sda5 during installation

UUID=058b6235-7e74-42ce-96c9-59f6cb0a44f3 none            swap    sw              0       0

# /media/hdd on /dev/sdb1

UUID=40a50699-a900-4bfe-a9e4-6587c1a83464 /media/hdd        ext4    defaults    0       2

You may need to change the ext4 to something else if your other drive is formatted differently.

Check to make sure mounts properly

mount /media/hdd

and see if it works.

make sure permissions are okay in /mnt/hdd/home/username
```
ls -l /mnt/hdd/home/username
```
where username is the name of your user.
if the permissions look okay skip, if not (still with root)



chown username:username -R /media/home/username

Link directories you want in home with those on the ssd

These can be done with user permissions, I would suggest you do this with empty directories: For example Pictures



cd ~

rm -rf Pictures

ln -sf /media/hdd/home/username/Pictures .

Do this for any directory you expect to take too much space, for me it's Pictures, Music, Documents, Videos

(optional) Carefully clean up the /media/hdd/ directory with root permissions. By carefully I mean do not delete /media/hdd/home !
