I think I see two potential issues.

First, there were a number of fixes to the ffs code to make it work better=
over 2 TB, and I don't think they are in 2.0. I am uncertain if they are=20
in the 2 branch, but I don't think so.

I don't know if the twe driver is 2TB clean or not. However if you use=20
RAIDFrame, this may not be an issue.

Take care,
