Description of problem: If you have one disk, you cannot create partitions to be software raid devices. Version-Release number of selected component (if applicable): f18 How reproducible: always Steps to Reproduce: 1. only one disk availabe on the local standard disks screen 2. manual partitioning, set up a new partition 3. no option to select software raid for the file system type Actual results: no option for software raid Expected results: select a software raid file system Additional info:
Well, you've got to have enough disks for the type of RAID you want to set up. anaconda does not support degraded installs in any respect, nor do we have plans to do so. Is that what you are trying to do?
I know it defeats the purpose to have raid partitions on a single physical drive. Let me explain: If someone is wanting to learn about the inner workings of raid, they want to learn how to add and remove devices from a working raid configuration. They need to know how to replace a failed device, and so on. The easiest way to do this kind of testing/learning, is to set up a bunch of raid partitions, put them in a raid group, assign a mount point. Boot the test system, simulate failed devices, add/remove raid devices, etc. They can figure it all out before they actually use it on the real hard drives. Not being able to set up a fully functioning working raid environment hinders their ability to learn. I know its kind of pointless to set up raid on a single drive - just because you can doesn't mean you should. However, fedora is not meant for production. Taking away functionality isn't a good thing.

If you want to learn about md raid, you should be doing that using the mdadm tool -- not anaconda. > > I know its kind of pointless to set up raid on a single drive - just because > you can doesn't mean you should.

Taking away functionality that doesn't make sense for the vast majority of users and which could in fact be detrimental to others can absolutely be a good thing. The installer is not going to support a setup that violates any and all best practices just to make it easier for you to learn about md raid without actually using the md raid tools themselves. It wouldn't make any sense whatsoever. It will be a small amount of extra work for you to create your partitions outside the installer, but you will end up with a better knowledge of how md raid works, which seems to be your goal.
