Description of problem: When running the Fedora 7 installer, when selecting the drives, the Fedora installer treats identically sized drives on an VIA KM266 chain as a software raid, rather than as separate drives. No RAID is configured in the bios. The type of RAID also is a little interesting. On identically sized 120gig Maxtor Drives, the KDE LiveCD configured the drives as a spanned raid. On identically sized 60gig Seagate drives, the drives are mapped as mirrors. The consistent portion is the drives appearing as mapper/*something* When only a single drive is present, or when identically sized drives, but different models are present, the installer presents the typical hd/sd entry tag. This is somewhat complicated by a single drive on the slave IDE channel reporting as /sda, even when another drive is present on the master channel. An additional issue from this is the lack of an option to choose a different drive than the one automatically selected for installation if a previous Fedora installation was present. Version-Release number of selected component (if applicable): Fedora 7 DVD / Fedora 7 KDE LiveCD How reproducible: Reproduced on Seagate and Maxtor IDE drives, 60gig on the seagates, 120gig on the Maxtor drives. Encountered installation problems on FIC AM37 motheboard : chipset listed as VIA ProSavageDDR KM266 Steps to Reproduce: 1. start installer 2. get to drive selection screen 3. find that a software RAID has been set Actual results: No install was completed. Had to swap out drives for one that the installer wouldn't try to set a RAID on. Expected results: Most other Linux's, exampling Mepis and PClinuxOS had no problems correctly assigning HDA status, and had no problems not setting as Software RAID on the drives. Additional info: I'm not really expecting anything to come out of this. I can't imagine that most testers have identical model drives in order to test different versions of an Operating System on identical hardware.
Do you have RAID enabled in your BIOS? It sounds like there is existing IDE "fakeraid" metadata on the disks and so we set them up as such. Adding 'nodmraid' to your boot command line should tell the installer not to listen to this information.
the BIOS has no RAID option set. Other distributions, as stated specifically Mepis and PCLinuxOS, experienced no issues in assigning correct identification to the drives.
There is a bug where the dmraid stuff just blocks. This bug has not been solved yet and we are still working to fix it. However there is a work around. If you use nodmraid, the installer will ignore/skip the dmraid stuff allowing the install to finish. This is a workaround and does not fix the problem. There is a long list of bugs that are filed against this problem. This bug is one of them. We have decided to close all the related nodmraid bugs and leave just one open that will represent all of the others. So this bug will be duped for this reason. *** This bug has been marked as a duplicate of 409931 ***
