Wait for it.  Hopefully later tonight in BLFS.

BLFS does have parted, jfs, and xfs.  They will handle a 2T+ partition.

jfs will handle 32P partitions.
xfs will handle 16E partitions.

T = 2^40 bytes
P = 2^50 bytes
E = 2^60 bytes

The largest dive I can find right now is 4T, so I guess I need to go get 
8192 of those to get to a 32P partitions.  :)

I'll have to wait for one of those 16E partitions.  :)

It will be fine for BLFS.

See BLFS 5. File Systems.  Already includes lvm2 (but not how to use it).
