what's the problem of LINUX MINT installation on RAID1?


I am installing Linuc Mint Rebecca on this computer: CPU: I7, motherboard: ASUS X99-A, HD: 2x 2TB, motherboard BIOS RAID1, so the total hard drive size is 2TB

While I was installing LINUX MINT on RAID1 hard drive, the installation system pop up ??? ???windows at Wher Are You step, after I click OK, jump to Installation Type, no matter which type I select: Erase disk and install Linux Mint or Someting else, ??? error message pop up at Where are you.

And if I click either of the two disk, it shows "Unable to mount location"

however, I can double click and see the content of RAID1 2TB disk.

Question: what's the problem of LINUX MINT installation on RAID1?

The motherboard-based "FakeRAID" has been known to cause issues installing and running linux for years. Generally speaking, only Windows + special drivers usually work on those motherboard-based controllers with the drives configured in a RAID configuration. (Google "fakeraid linux" for more info)

If you wish to install linux I'd change your SATA ports from RAID to AHCI in BIOS and go from there. However, it sounds like you already installed Windows on the computer... If so, that would break that configuration

Linux has some pretty good software-based RAID using the mdadm utility, which can be configured through most graphical linux installation utilities. It's incompatible with Windows, though, so if you're wanting to have linux and Windows on that system you aren't really going to be able to have them both on there in a mirrored RAID configuration unless you purchase some kind of hardware-accelerated RAID controller that supports both operating systems (and they're usually not inexpensive).

It's one of the more unfortunate incompatibilities between the two OS's, but it's not the fault of linux; moreso it's the lack of the fakeRAID manufacturers not creating drivers / releasing info to make them available for linux.

If you're just exploring linux for the first time and seeing how things work, and you want to keep your hard drives in a RAID1 mirror, perhaps installing something like VirtualBox (https://www.virtualbox.org/) or VMWare Player (https://my.vmware.com/web/vmware/fre...are_player/7_0) on your existing Windows installation would make more sense; either would allow you to install linux in a virtual machine running on Windows, and you could still play around with it there.

Even better, you could try all sorts of different linux distributions (not just Mint), and find the one you like the most! All without endangering your existing Windows.

I assume that strick1226 pretty much has it. Check for a software raid controller or as commonly put, fake or faux raid.

One can also try a usb install to a spare usb flash or usb drive usually if they are careful.

The most safe is a free virtual machine.

I am thankful for strick1226 and jefro, both of you are right. Steer away from fake raid, I changed back to soft raid. Obviously Virtual machineis is best choice, but I want to create soft raid firstly.

Thanks for the update and solution.

Some distro's can see faux/fake raid cards correctly. Might be able to get it working on your distro. I just do like you say, steer clear of them.
