I have to admit I haven't seen a simple partition table like that for ages.
Why did you put swap first on the disk?
By contrast, here's my desktop, which is still FC13 based.
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 4098047 2048000 fd Linux raid
autodetect
/dev/sda2 4098048 490233855 243067904 fd Linux raid
autodetect
which leads to:
[~]$ cat /proc/mdstat
Personalities : [raid1]
md5 : active raid1 sda2[0] sdb2[1]
243066748 blocks super 1.1 [2/2] [UU]
bitmap: 1/2 pages [4KB], 65536KB chunk
md0 : active raid1 sda1[0] sdb1[1]
2047988 blocks super 1.0 [2/2] [UU]
So /boot is a raid1, the machine could use either to boot. When the OS
is up, both bits are synched.
[~]$ sudo pvdisplay

md5 is a raid1 also, which is a physical space for LVM
[~]$ sudo lvdisplay

Inside the PV there are two LVs and some spare space, so I can expand
either partiiton or make a new one as I see fit.
So here's the mount table
[cfalconer@ttt07 ~]$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/vg_0-root
100791728 15221400 80450328 16% /

I've done similar for a mythbox for a coworker.... sda 160 GB + sdb 1TB
md0 first 500 MB of each disk raid1 for /boot
md5 Rest of sda plus 159 GB from middle of sdb as a PV for LVM
/mythdata 700GB as sdb3
Any questions?
