Can't use fdisk after RAID5 reconstruct.

This system originally had a RAID5 Array with 3-each 146GB Disks. Total disk usable disk of 280GB of space split into 2 logical volumes and some standard partitions.

I added an additional 146GByte disk to the array this weekend from the Ctl M menu selecting an array reconstruction. The new array now reports about 419.7GBytes in size which is correct.

My problem is that I can’t create a partitions using fdisk or parted using the new space. Also fdisk reports the wrong size. fdisk reports a disk size of 440GB instead of 419GB.

Fdisk -l

Disk /dev/sda: 440.0 GB, 440087347200 bytes255 heads, 63 sectors/track, 53504 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

If I try to create a partition with fdisk, I get an immediate error. “No free sectors available.”

Parted returns “Unable to satisfy constraints”.

I sent a sysreport to Dell support and they said everything seems fine and suggested I just wipe everything out and start all over again.

Before I do, does anyone have any ideas on how I can create a partition using the new space?

Thanks,
