Software RAID1 + LVM on FC5

[Daisy]

I was hoping someone could point me to a good tutorial or maybe throw out some tips on software RAID1 + LVM for FC5. I tried setting it up during install but it's not working right and I'm not sure what's wrong. Being a total linux noob I can't seem to figure out what to do next. Maybe these things can help you to point me in the right direction...

fdisk -l shows:

Disk /dev/sda: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System

Disk /dev/md1: 319.9 GB, 319963267072 bytes
2 heads, 4 sectors/track, 78116032 cylinders
Units = cylinders of 8 * 512 = 4096 bytes

Disk /dev/md1 doesn't contain a valid partition table

Disk /dev/md0: 106 MB, 106823680 bytes
2 heads, 4 sectors/track, 26080 cylinders
Units = cylinders of 8 * 512 = 4096 bytes

Disk /dev/md0 doesn't contain a valid partition table

and cat /proc/mdstat shows:

Personalities : [raid1] 
md0 : active raid1 sdb1[1]
      104320 blocks [2/1] [_U]
      
md1 : active raid1 sdb2[1]
      312464128 blocks [2/1] [_U]
      
unused devices: <none>

which is all fine and dandy but I don't really understand what it all means. I'm trying to setup two disks to mirror each other so if one fails the other picks up the slack. Simple redundancy (not worried about speed) I appreciate any help.

Thanks!
