raid5 problems

I'm using fc3 on nforce3-250Gb mobo (AMD-64).

I managed to get md raid working on my two sata drives, but I have now added a couple of promise EIDE controllers and 4 disks on their primary EIDE channels.

I managed to make raid5 work on them, but had to create /dev/md1 manually (mknod /dev/md1 b 9 1), and force an xfs file system to be created (mkfs.xfs -f), which seemed to cause problems later on due to something being wrong with the superblock (not sure what that is about). I am also finding that /dev/md1 disappears when I reboot.

I thought I might be able to fix /dev/md1 disappearing by putting some custom code in some init.d scripts, but I see from the messages in /var/log/messages, that the kernel actually does stuff before it even gets to init.d (is that right?).

I have no idea how to fix the xfs problem.

How should we configure xfs/raid devices after the first one?
