Which is it? 1TB or 3TB?

Comment 3 Steve Simpson 2011-09-07 15:07:51 UTC
Please read the referenced FC bug report. I don't know exactly where the limit lies and it may be (somewhat) dependent on the architecture of the (virtual) drive. The initial reporter stated that he had problems with 1.5TB drive. My original configuration was with a 3+TB. My guess is that it is slightly over 1 TB.

Comment 4 Peter Jones 2011-09-15 13:42:13 UTC
I've successfully used 2TB drives to boot from, so this appears to be a problem with >2TB boot volumes. This is unsupported on BIOS machines.
