Well, you were right. Rod Smith of rodsbooks.com suggested the same thing in an email.

1- I moved some data from two larger partitions in the first 2TB onto other data partitions later in the disk.
2- I rebuilt the CentOS 6.6 /boot in a new 1GB partition in the first 2TB
3- I rebooted into grub2 command-line, lo and behold, it sees the filesystem.

Thank you, Andrei.

Now, if only I could figure out why os-prober will not create menu entries for that /boot....

Hi Andrei,




What you *can* see on this disk? It is possible that we face BIOS issue
with access too far from the beginning of disk. Which is the last
partition you can see?

grub command-line can see all of the partitions, but only sees the filesystem on sda2. 

Sigh, I guess I can free up some space with the oversized partitions, and create other smaller partitions just for boot, then let those kernels deal with larger disk and partitions.
 
Try loading lvm module, which volumes become visible?

I didn't think of that. I will boot now and try it.

 
Also retest with current master would be good.

As in latest off master branch?
