I've been searching for a definitive answer/solution for this. Below are 
outputs from fdisk -l and a partition table listing from expert mode in 
fdisk.

[root at ncc1701 ~]# fdisk -l /dev/sda

Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000265ce

Device Boot Start End Blocks Id System
/dev/sda1 * 1 39 307200 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 39 60801 488076288 83 Linux

This is what it looks like in parted:

(parted) print
Model: ATA WDC WD5000AAKS-6 (scsi)
Disk /dev/sda: 500GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number Start End Size Type File system Flags
1 32.3kB 315MB 315MB primary ext4 boot
2 315MB 500GB 500GB primary

Some posts that I've come across indicate no problem while others 
indicate that it is an issue and needs to be corrected. sda1 is my /boot 
partition ~ 300MB and then sda2 is a LUKS volume with a LVM VG occupying 
the rest of the available 500GB hdd. It is my active F 12 system with no 
dual boot.

1. Is it a problem?
2.Can I just resize sda1 so the end does not overlap sda2?
3. And can I do this while booted from that system or do I need to do it 
from a LiveCD?
