From: Jozsi Vadkan on 7 May 2010 07:30 Did anyone managed to boot from RAID1? Lenny gives this error message: "mdadm: no devices found for /dev/md0" I just want to install Debian Lenny on two pendrives [in sRAID1], so that the HDD's in the pc can be used only as ""data containers"", but it gives this error message. Please help me. Thank you! -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

If you don't know why this is happening, then you shouldn't be doing this! This is because you don't have the md driver _in_ the kernel You'll need a small i.e. 20-30MB partition out of raid to boot from with i.e. initrd which loads the md driver and your raid device becomes visible. It doesn't matter if it's a pendrive or something else. regards -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

From: Jozsi Vadkan on 7 May 2010 08:50 But i thought that, I can boot from RAID1 under Lenny. So i can't? So the solution is that I need a separate /boot partition? But the RAID will be useless then... 2010. 05. 7, péntek keltezéssel 14.22-kor deloptes ezt írta: > Jozsi Vadkan wrote: > > > Did anyone managed to boot from RAID1? > > > > Lenny gives this error message: > > > > "mdadm: no devices found for /dev/md0" > > > > I just want to install Debian Lenny on two pendrives [in sRAID1], so > > that the HDD's in the pc can be used only as ""data containers"", but it > > gives this error message. > > > > Please help me. > > > > Thank you! > > If you don't know why this is happening, then you shouldn't be doing this! > > This is because you don't have the md driver _in_ the kernel > > You'll need a small i.e. 20-30MB partition out of raid to boot from with > i.e. initrd which loads the md driver and your raid device becomes visible. > > It doesn't matter if it's a pendrive or something else. > > regards > > > -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

You can also try debugging the initrd you are using to see what is going on or give us more information on your setup - partitioning, grub/lilo setup etc. there are many ways to get the job done! regards -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
