Please help. At boot time, we get: "Alternate GPT header not at the end
of the disk."
Google shows some situations like this are resolved by running parted and
using "print" to trigger an offer of "Fix/Cancel". I don't get such an
offer.
We have parted 1.8.8 on Fedora 10. There is an important XFS file system of
17TB spanning sdc (healthy) and sdd (sick). The only recent change was to
add sde to scsi interface shared with sdd. Output from /var/log/messages and
parted diagnostic print commands is below.
What should I do now to resolve this? I would believe it is critical to
resolve before I grow the file system to 25TB. Is it?
Thanks,
Ralph
