bootable failed sw raid 1 with F9
Hi list, For the first time in my life i tried to install Fedora with sw raid. See below what went wrong. Here is what I did: Start with 2 empty 500GB sata disks. Make sure nvraid is turned off in my BIOS. Start an F9 install, creating 2 sw RAID partitions: md0 and md1. md0 is 100MB and has an ext3 /boot. md1 has the rest of the space and is LVM. In the lvm I have created the rest of my partitions. Install went great, after reboot my system booted fine, so far so good. I then shutdown my system, pulled out a disk and started again. I got the message "GRUB Hard Disk Error". So I shut down, plugged the disk back in, pulled out the other one and started again. This time I was met by a GRUB shell, no boot logo, no idea what to do (no menu). Shutdown again, replug the disk, start again, get on IRC, type: grub root (hd0,0) setup (hd0) root (hd1,0) setup (hd1) After that: reboot minus 1 disk. I can see grub, with logo and boot options. It starts ok, i even get rhgb for a second and then I see: "fsck.ext3: Invalid argument while trying to open /dev/md0" I can go into a maintenance shell and when I do cat /proc/mdstat is see: md0 : inactive sda1[0](s) "mdadm --assemble /dev/md0" turns it active again, but well I have no idea how I can continue normal boot, if it is even possible. So this is my story, now my questions: - Did I do anything wrong? I performed the installation twice, with both times the same result. - Is this a bug somewhere? Do other people get the same or better results? - Is there anything I can do to fix this?

Again not sure if your reply is to me, but from my email you can read this is not the case for me.
