I want to install Ubuntu 16.04 Desktop on a pc with two 2T HDs (no other OS). My endpoint is to get Ubuntu installed on a partition set as RAID1, the swap set on a partition with RAID0, and a third partition for data storage set as RAID1 again.
I've created 3 partitions in each drive with GParted from live usb: sda1 (ext4), sda5 (swap) and sda6 (NTFS). Same configuration is set for sdb.
Now I would like to set sda1-sdb1 in RAID1 (as md0) where to install Ubuntu (this should be the booting point),
sda5-sdb5 in RAID0 (as md1) for the swap,
sda6-sdb6 in RAID1(as md2) for data storage.
I've tried to set the three RAID volumes using mdadm from live cd (and it looked I manage to successfully create the md volumes), but when I try to install Ubuntu from the live usb, it does NOT find the md volumes but only the sd ones. How can I install it on the RAID drive?
I've read there should be an Alternate CD with more advanced installations options, but is that still available for 16.04 ?
