Dual boot windows 10 / Slackware 14.2 and software RAID
 
My computer has INTEL fake RAID, but after many days of research it seems impossible to install Slackware with this configuration.

Even discovered what is FAKE RAID...

So now I have this computer, which has two 256 GB SSD samsung disks.

I could say, ok, let's completely drop RAID and do a good old fashion dual boot windows and Slackware.

Honestly, I don't have use for 512 GB space...

So let's challenge this. Anyone has tried to do dual boot software RAID (Storage spaces for windows) ?

Which partition configuration did you choose?

You mention Intel fakeRAID and Storage Spaces for Windows. They are not the same thing at all.

mdadm is supposedly able to handle Intel fakeRAID sets. See if there's a device in /dev/md that corresponds to your RAID set.

I install Slackware on systems with fakeRAIDs fairly often. I use a modified install image with dmraid, which handles most fakeRAID metadata types. Unfortunately only RAID1 works, due to changes to RAID4/5/6 kernel support that were made after the development of dmraid ceased.

In either case, booting Linux from a fakeRAID set requires an initrd with RAID support.

Hi Ser Olmy,

when I launch my Slackware installer (uefi so grub) and go to cgdisk /dev/md126 I can see the partitions and edit but unable to save.

When I do a cat /proc/mdstat I can see a RAID 1 active but as read only...

I mentioned Fake RAID and Software RAID, but what I meant was that because I didn't manage to do FAKE RAID dual boot configuration, has someone some tips about how to configure a dual boot with software RAID.

But if you have a step by step to configure a dual boot with fake RAID, I'm ON. So please enlight me.

How do you do this? Please. Really want to work on this. Cannot get rid of windows because I use it for my work.

Tried installing mdadm from package and now, after running these lines I was able to change partitions with cgdisk

mdadm --stop /dev/md126
mdadm -As

It changed the state from active (read-only) to active (auto-read-only).

But Slackware setup shows two swap partitions and two partitions available for root. sda and sdb

There is also a md126 partition in the root folder selection... With full disk space indication.

I'm really the only one who wants to do this?
