I am new to raid installations. I have installed Fedora 2.0 onto a 
system with two identical drives that I configured to be a raid1 mirror 
through the disk druid interface. I created partition mirrors for both 
the /boot partition (md0) and the / partition (md1). Then I created same 
sized, non-mirrored swap partitions on each of the identical drives. 
After the installation process, I found that I could boot with both 
physical drives online and only one of the two physical drives when 
booting in a single drive (failure simulation) mode.

I am wondering if there is a required kernel module that is not loaded 
or compiled into the default Fedora 2.6 kernel.

When I look into the process list I see processes called md0_raid and 
md1_raid. I did not run the raidstart command but assume that it 
probably has been run.

Also here are a few raid file listings:

/etc/raidtab

raiddev             /dev/md1
raid-level                  1
nr-raid-disks               2
chunk-size                  256
persistent-superblock       1
nr-spare-disks              0
    device          /dev/hda3
    raid-disk     0
    device          /dev/hdd3
    raid-disk     1
raiddev             /dev/md0
raid-level                  1
nr-raid-disks               2
chunk-size                  256
persistent-superblock       1
nr-spare-disks              0
    device          /dev/hda1
    raid-disk     0
    device          /dev/hdd1
    raid-disk     1

And /proc/mdstat

Personalities : [raid1]
md1 : active raid1 hda3[0]
      242958848 blocks [2/1] [U_]

md0 : active raid1 hda1[0]
      104192 blocks [2/1] [U_]

unused devices: <none>


Thanks for any help.
