Description Olivier Pinard 2011-06-04 01:35:54 CEST

Hello, before I start to explain what is the problem, I am a French mother tongue speaker. Sorry for my bad english.

So, an french users of MLO report than Raid1 is not very well supported by Mageia 1 for an install on FakeRaid. The users report than need for is update of 2012.2 to Mageia 1 to go on terminal tty2 and does : service dm stop . for stopping graphic interface ; cd /etc/urpmi ; cd /etc/urpmi ; cp urpmi.cfg urpmi.cfg.mandriva . After, it start the update.

So, after is install, Mageia don't detect fakeraid, it only detect sda and sdb. It have to run the 2.6.33 linux kernel from mandriva because the 2.6.38 don't know how to be install on raid1. In /boot, the initrd of mageia was not been build and it is not easy for him with a raid activate when mageia don't detect it. Material detection bug on the boot. The nvidia drivers don't work. He have to use the nv drivers. So, the Mandriva 2010.2 don't detect Raid too. Debian 6.0 work with raid1 and detect it. The users think it is the new kernel versions than don't support it anymore. The Raid1 was been create with Mandriva 2010.0 on a fresh install. Now, the only way than Mageia support it is with 2.6.33.5-desktop-2mnb kernel.

Computer information :
MB : ASUS P8P67 Rev B3 with half Raid material activate
CPU : Intel Core I7 2600K
RAM : 4Go from GSkill
GPU : Nvidia 9600GT

OS :
Mageia Final Release 1
Kernel :  2.6.38 (default install)
Bug package : Kernel  2.6.38 & Fakeraid
Desktop Environment : KDE

Thank ! ^_^

Hi, I'm the guy who reported the bug on the MLO french forum.
I just have to add that the Nvidia card isn't able to work with the 270 proprietary driver just because I don't have the 2.6.33-5-devel rpm installed and dkms is unable to compile it without the kernel sources of the current kernel I'm using (2.6.33-5). 
I can add that XFCE4 disk applet is telling me that one of my 1Tb disk isn't OK.
But both SMART and Seatools are telling me that all is OK on both disk...

Fakeraid is the worst option of the three (soft, fake, hardware). As there is enough cpu power i would create softraid arrays as this solution is more bulletproof than fakeraid.

I agree with you but that didn't explain why I could use this solution with Debian 6.0 and not with Mageia.

Funny, on june 5th, the French user Olivier filed this report for, Polo 35, said:

"Ãa fait du bien de changer de distribution de temps Ã  autre. J'ai été obligé de mettre le nez dans le moteur et j'ai trouvé que mon raid1 était désynchronisé depuis sans doute un bon bout de temps !"

So his raid1 had been desynchronised since before installing Mga

Anyway, he later opted for software raid and his problem was solved.

Closing this bug as worksforme
