Hi
In the hope of avoiding a few problems, I thought it would be a good idea to seek some advice before I go ahead with my planned Ubuntu installation.
I've been monitoring the progress of Linux over several years and, when I built my latest PC last year installed two RAID1 arrays with the intention of installing Ubuntu on one of them. Win7 is already installed on the other array, and the idea is to dual boot them. My PC uses an Asus M4A89GTD PRO / USB3 motherboard with a AMD SB850 chipset supporting 'fakeRAID' configured through the BIOS.
I've not installed or used Linux before, so simple explanations would help, if possible!
According to my research so far, it seems that the installation of Ubuntu on a fakeRAID array should now be easy / easier, since (to quote the Lucid Lynx Release Notes (https://wiki.ubuntu.com/LucidLynx/ReleaseNotes)) 'Dmraid "fake raid" devices are supported out-of-the-box on the Ubuntu 10.04 LTS Desktop CD, and are detected and activated by dmraid on boot. Ubiquity will offer to install on the RAID array, and not on the RAID members.'
Q1)
Does this mean that the tutorial at https://help.ubuntu.com/community/FakeRaidHowto is entirely superseded, and that it's statement that 'FakeRAID is not supported by Ubuntu' is now entirely incorrect? Or are there still some special steps / precautions to look out for? I can't find any updated guidance since this change - just plenty of dire warnings pre version 10.04.
Q2)
The 'spare array' is already partitioned since I've used it for some other purposes. Other than reformatting one of the partitions from NTFS to ext4 for Ubuntu, are there any other considerations? For example does Ubuntu insist on being installed to the first partition / not on a logical partition?
Q3)
Since Win7 and Ubuntu would keep their own arrays (other, perhaps, than putting their swap / page files on the opposite array for a little added performance), what is the best method for dual booting them - and how and where should the software be installed?
Q4)
Is it likely that this installation would require any special precautions when upgrading to future versions?
Q5)
What else should I be thinking about?
Thanks in advance for your advice...
