Can you confirm whether I have set up my partitions correctly on a 1 TB SSD for ubuntu(mate)?
Partition Table

  • I am missing the mount points, I understand that you want to have 800GiB for /home and 20GiB for /, isn't it? – Zumo de Vidrio Jan 3 '17 at 13:29

    20 GiB for / is a bit on the stingy side; I would allocate more space -- maybe 40 GiB. If the 100 GiB unallocated space is intended as overprovisioning then I'd say that you can reduce it to 50; if it's intended for another OS then you should consider leaving some space unallocated for overprovisioning -- 50 GiB should be nice. – AlexP Jan 3 '17 at 13:39
  • You missed /boot partition = 500 MB , / partition of root = 40 GB when you did it as Server too. Because you didnt create /usr partition and /var partition. – supriady Jan 3 '17 at 13:39
  • use gpt to have more than 4 primary parts; and to avoid lot of troubles in future ; partitionne the first 200 gb in any way you like ; and creat 800gb at the end (for your files); in the future you'll like to test other OSs ... you will be able to reparts the first 200gb without touching your data(800gb) ; and yes 200gb is enought for many linux/unix alongside systems; NOTE repartitionning causes lose of memory capacity ; with this plan you'll kep your 800gb away of this effect ! – Jonas Jan 3 '17 at 14:01
  • 1 question What is the purpose of setting partition flags? Many 'recipes' that I have been following such as ubuntu-mate.community/t/… >Part 4: Create a UEFI boot partition. + swap + root + home partitions. don't even mention them. – Bachalo Jan 4 '17 at 12:34

For disk management always try to maintain partition by LVM not standard way. It will be better for you to resize your partition any time without data lose. But production environment keep it minds maximum /var and /home mount point are used. So it will be better if you allocated maximum size on /var /and /home.
