I have a very powerfull system comprised of i9 12900k CPU Water Cooled, 64Gb Ram, Four x 990Pro M.2 1TB SSD's, .
I have just installed Fedora 37 Cinnamon.
And during the install I created the Stripe Array.
But I have No Idea of How to Manually Partition the System.
If I use the custom layout , I end up with No Space to Install or Save Anything.
My Existing Disk Layout, as shown with ( Disks App ) is, 1TB Disk , File System 230MB fat 32 , File System 730mb Ext4 , Partition 3 450Gb Raid Member , fedora local partition 268 mb Btrfs , Free Space 550gb.
Then they list the three disks as having , Partition 1 448gb linux raid member, fedora loacl partition 2 268mb btrfs, free space 552gb.
Then they list one for the raid0 array as /dev/md/root00 with a filesystem of 1.8 tB Ext4
Can this Ugly Layout be Changed Now or do I have to Wipe it all and Reinstall the O/S.
If I have to reinstall could someone point me to a proper Instruction sheet for Raid0 Setup.

Do you have other partitions on the other 3 M.2 drives?

Here's a step by step guide:

Step-by-Step Tutorial: Configure Software RAID 0 in Linux | GoLinuxCloud

Steps to configure software raid 0 with examples in linux. With RAID 0 there is no data redundancy as the data is stored in strips but this has better speed.

Thanks for that Link, But it is of no use to me as it describes the creation of raid using mdadm from within linux.
And what i am talking about is installing fedora 37.
 
You have to reinstall and select your partitioning during setup and then configure raid, when you start the installer you have to delete you current partition setup before you can start creating a new setup because otherwise it will say you have no space because the current partitions have everything in use.

Make sure you have the correct SSD selected before you delete the partition in the partition manager that Fedora prompts you with.

This looks like a place to start-

Setting up a Software RAID on CentOS and Fedora with mdadm

In this article I’ll explain how to setup a software RAID on Fedora. This will turn any number of attached USB drives into any flavour of RAID without the necessity of a dedicated enclosure. …

Thanks, I Checked that one out, But it only talks about setting up raid from within linux on existing drives.
Anyway I have Solved my Problem for the time being that is, by going back to windows.
End of discussion for me .
Thanks to all, Bye
 
1. Select disks.

2. Create ext4 /boot partition since it doesn't seem possible to boot from a btrfs raid device.

Note: You can ignore my biosboot partitions because I installed it in a vm.

3. Create btrfs root subvolume.

4. Create btrfs home subvolume.

5. Modify the volume to the right where it says volume below there you can select "Modify". There you can select RAID0 then click save, you can rename the volume to something different if you want.

Thanks to all.
I have taken everyone's advise into account and for the time being I have fixed my problem, I have gone Back to Windows.
End of discussion for me.

If that works for you great!

I spent over an hour perfecting my screenshots in the hope that they would help you, now all my time put into it seems to have been for nothing :(

They're pretty good screenshots.

It sucks when that happens.

HOWEVER...

Those screenshots and directions may very well benefit someone with more patience and gumption. Eventually, especially considering how the site ranks in search engines, someone's gonna come along and use those directions. Dunno if they'll publicly thank you 'cause the thread might be old by then and they may not think to do so, but someone'll eventually find 'em useful.

But, yeah, it sucks when that happens.

The good things that you do for people have not been over looked.

There is an internet full of people who have been using web searches to find your many helpful posts and then using them to solve their problems. Most of the time, they are listed as "guest".

As I write this, there are a total of 307 people on the website. There are only 11 members connected, but 296 guests. At this very moment, some of those guests are looking at your screenshots and configuring their own RAID 0 setups.

Your efforts are never in vain, and are much appreciated by all.

Alas, most of those will almost certainly be bots, both good and bad ones. The 'online guest' thing isn't all that intelligent. They're all the search engines, statistic keeper, advertisers, etc - and then there are the bad ones. Those would be bots that are trying to post, scrape, find exploits, etc... They all get counted as being online if they're hitting a web page or trying to.

That doesn't detract from what you're saying, some of 'em are still people. From my research, of which I have done a whole lot of, about the most accurate traffic measuring is done with Awtstats or your own instance of Matomo. I am not privy to such information on this site.

Thanks for that info, and thanks for your research and compiling this info, it is much appreciated.
As I said earlier I was done for now and going back to windows, well I have but I still would like to use fedora 37 with raid0 on my four SSD's. What I don't understand is just how many partitions I should have and their sizes.During the raid build I am offered to add partitions, and from memory there is about 6 types in the list. Like \ , \root , swap , home etc. is there some general rule for this or is it up to each persons specific pc build. My PC Specs are , MSI Motherboard Pro Z690-A , 64gb ram, Four Samsung 990Pro 1tb M.2 SSD's, intel i9 12900k CPU Water Cooled, onboard GPU etc. I have installed fedora 37 beore a few times in raid0 , but it's all been hit and mis, not knowning which partitions to setup and what size each one should be. And which ones to include in the raid0 build. What I would like is to use all four drives in the raid0 build . I don't care how much space is allocated to all the other partitions as long as I have about 3tb in the home or user partition. I have worked with raid for the last 20 years with windows but not with linux, And as I said I have already achieved that goal with fedora 37 on my new system, it's just a matter of getting the sizes and number of partitions sorted out

You don't have to worry about partitions, in short you basically select all four disks, then create volumes and select their filesystems, if you select xfs/ext4 those will be logical volumes in a volume group and if you select btrfs those will be sub-volumes under a top volume. Then under volume to the right (where you created your fileystem volumes) you have the option to "Modify" your volume and there you can select what raid level you want to use. Also you can skip creating swap because Fedora automatically creates zram to use as swap.
