Should I be Worried: sda: p1 size .... limited to end of disk

[Eddie <stunnel@attglobal.net>]

After the fun and games with my other LSI MegaRAID card, I'm a glutton 
for punishment.

I'm building another system, which this time, has an LSI MegaRAID SATA 
300-8X controller in it.  This appears to be working perfectly, and a 
lot faster than my other card, with the exception of this warning 
message during boot:

sda: p1 size 2930304132 limited to end of disk

Is this something I should be worried about, and how does it come 
about.  I built a new RAID 5, Logical device, on the card, which the LSI 
utility says is 1430511MB in size.

Here's the relevant output from DMESG:

And /proc/partions:

And fdisk:

Disk /dev/sda: 1499.9 GB, 1499999502336 bytes
255 heads, 63 sectors/track, 182364 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0003d809

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1      182403  1465152066   8e  Linux LVM

So, where is the discrepancy creeping in.

Also, I see this in DMESG:

sd 4:1:0:0: [sda] Assuming drive cache: write through

But, as this card has a battery backup, I have it set to "Write Back" in 
the configuration.  So, what mode is it really operating in.

Cheers,
