IO error reported there. Or it's trying to read past the end of the
block device due to bad info in the filesystem's superblock.

Heh. I can't say I've ever tried badblocks it on a 7Tbyte device
before. Could be a badblocks bug. Or something else. Let's go back
What does /proc/partitions say about the size of this device?
Is the kernel still reporting IO errors on sdd?
What sort of drive is this? LSI53C1030 seems to be a Ultra320 SCSI
HBA. What sort of target is sdd? Is it a RAID box of some
description? (I'd think it has to be based on it being 7Tbytes in
size.) Are there any diagnostics you can do on that device? Has it
maybe lost a component drive?
How does "lsscsi" identify sdd? (Assuming you have that installed.)
