2930266583 x 1024 == 3000592980992
I'd rather see what /proc/partitions and/or blockdev says about it...

732566646 x 4k blocks == 3000592982016 bytes
Ok, that is 1024 bytes bigger. But the weird thing is that
mkfs.xfs actually writes the last block, and fails if that fails.
So let's start with what /proc/partitions says, as well as
# blkdev --getsize --getsize64 /dev/sdf
