Description Caspar Zhang 2013-05-29 13:01:18 UTC 
Description of problem:

When trying to install a system on a 4TB disk, we did the following operation:

remove a partition (not the first partition), and recreate it, the first sector (LBA0) of disk got changed unexpectedly, so the system is unbootable.

example:

# confirm it's 4TB disk and using GPT
#parted /dev/sda print

Model: ATA WDC WD4000FYYZ-0 (scsi)
Disk /dev/sda: 4001GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

# list first 2 sectors (LBA0 & LBA1 used by GPT)
#od -N 1024 /dev/sda

Upstream parted commit 14a1589194dc0adcebb6cca2ab2c2a87e1d26b38 should fix this. Note that RHEL5 doesn't support 4T disks for booting though.
