Feature request: Support RAID #987
Info regarding which version of Calamares is used, which Distribution
Provide information on how the disks are set up, in detail, with full logs of commands issued
What do you expect to have happen when Calamares installs?
Describe the issue you encountered
Steps to reproduce the problem
Include the installation.log (usually ~/Calamares/Calamares/Calamares.log, of the user Calamares runs as):
Good of you to refer to previous issues that were filed. I think part of the problem is illustrated in #794: I don't have that kind of hardware, and have no idea what it's supposed to look like when it is working. So it's a good feature request, but it's going to need someone to specifically work on it (and submit a PR which looks at least plausible, as opposed to just hacking in some extra calls to mdadm or whatever).
It's possible -- likely even -- that there is also an issue in KPMCore: does KDE partition manager see this kind of RAID'ed disks?
There is no difference to mdadm SW RAID on howto handle these , except two things.
Meaning for us once normal RAID is supported this:
On RAID UIX an 'Want INTEL FAKE RAID' kind option ( please note no magic can be really
Then offer the user to select his array name and jump over 'create your raid array(s)'
That is all to support that.
Uh, actually, the Linux kernel knows 2 kinds of RAID setups:
(True hardware RAID is entirely transparent to the kernel to begin with, so should need no special setup.)
As I understand it, what is requested here is support for
I might add that the Ubuntu and Suse Tumbleweed installer get this (mostly) right and recognizes the Intel Fake-Raid partitions correctly. The correct placement of the bootloader was a minor issue. Maybe a look into their sources could be a source for inspiration? By the way, mdraid is requested by me here as it is the suggested way even from Intel, see this White Paper from 2011: https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/rst-linux-paper.pdf

Hi, I am looking at moving over to Manjaro for my Gaming PC but this seems to be the one thing holding me back. I have a system with 3 SSD's that I like to put in a RAID 0 for performance as I am not worried about the longevity of my game binaries.
The following forum article says someone is looking into this but it has not been updated since late last year.
I am wondering what the current progress is and if it is going to be something that we may be able to see implemented soon.
If not, I am happy to try testing workarounds as I am currently doing using virtual machines with 3 small VHD's to try and get a RAID installation going.
To give an idea, I am partitioning the HDD's into 3:
I am then creating md0 and trying to continue the installation through the GUI but RAID drive is not visible in the installer.
Please let me know your thoughts at your convenience.
@Vfreeze31 as a workaround, assuming your interest is mostly in RAID-0 for the gaming bits, is to install Manjaro first to a custom partitioning scheme with just space for / (and possibly swap), then once the system is installed, set up the RAID bits by hand.
That said, Calamares master (will be 3.2.3) has some RAID features from Caio merged in. That may help. For 3.2.3 there is nothing particular planned for RAID support -- I consider it pretty low-priority compared to other fixes and improvements in flexibility of Calamares.
Features for full support for software RAID (i.e. mdraid) are almost completed in kpmcore raid-support branch, but I have to finish implementing some particular features and fixing some processes like resizing and deleting. I hope to get a time during the next months to code it.
