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
