This patch changes the way we determine if a logical volume is larger than 2TB. The original test looked for a total_size of 0. Originally we added 1 to the total_size. That would make our read_capacity return size 0 for >2TB lv's. We assumed that we could not have a lv size of 0 so it seemed OK until we were in a clustered system. The backup node would see a size of 0 due to the reservation on the drive. That caused the driver to switch to 16-byte CDB's which are not supported on older controllers. After that everything was broken. It may seem petty but I don't see the value in trying to determine if the LBA is beyond the 2TB boundary. That's why when we switch we use 16-byte CDB's for all read/write operations. Please consider this for inclusion.
