Clean installation of ubuntu in the SSD with HDD being used /home folder.
1. Installation of ubuntu
- Boot with live ubuntu CD
caution : disconnect internet, otherwise you will get retrieving error (stop at 43 of 53)
- Select erase and install ubuntu (second option)
- File system: ext4 or btrfs
- Complete installing ubuntu
- Boot with live ubuntu cd and select 'try ubuntu'
- Execute gparted partition editor
Remove linux-swap (It occupies too much space) Remove Exteend Extend /dev/sda1 to full capacity leaving 1 GB (1000 MB) Create Extended partition to allocate (1 GB) (partition type: Extended) Create linux-swap space occupying 1 GB 'Apply'
- Restart
2. Optimization to SSD
- turn on Trim
Edit /etc/fstab UUID=ac39c463-fe88-45ea-a4dd-f4eb6117141c / ext4 discard,noatime,errors=remount-ro 0 1
- tunr off swap
3. Mounting HDD to home folder
In case, mounting HDD containing home folder files, create all users before mounting to prevent overwritting.
To get more information, go https://help.ubuntu.com/community/Partitioning/Home/Moving
- Find the uuid of the Partition
$ sudo blkid
take note (copy&paste into a text-file) the uuid of the partition that you have set-up ready to be the new /home partition.
- Setup fstab
Duplicate your fstab file: $ sudo cp /etc/fstab /etc/fstab.$(date +%Y-%m-%d) Compare the two files to confirm the backup matches the original:
$ cmp /etc/fstab /etc/fstab.$(date +%Y-%m-%d)
Open the original fstab in a text editor:
$ sudo vim /etc/fstab
And add these lines into it
(identifier) (location, eg sda5) (format, eg ext3 or ext4) (some settings) UUID=???????? /home ext3 nodev,nosuid 0 2and replace the "????????" with the UUID number of the intended /home partition.
