Comment 7 for bug 107326

I had the same problem working with a 3TB array. I created 7 partitions on a gpt label with parted from 7.10 64bit desktop. I then used hdparm -z /dev/sda to reread the partitions, but the OS only saw the first 4. I then chrooted into SLES 10 and used the parted from it. It gave the same error message regarding the bad gpt label that has been reported already. I made 1 small change so that the SLES10 version of parted would rewrite the partition table, and then hdparm -z /dev/sda correctly read the partition table after that.

Also, I have a patched version of grub that works with gpt partition tables. I can provide it if necessary. This patched version also wouldn't work until I used the parted from SLES10. The parted from ubuntu 7.10 64bit desktop left the partition table in a state that would not work with my patched grub.
