II. Problem Description

The way mfi(4) implements access of "syspd" or also known as JBOD always
uses READ10/WRITE10 commands for underlying disk. When writing over 2^32
sectors, the LBA would wrap and starts writing at the beginning of the
disk.

III. Impact

Writing beyond 2TB to mfi(4) connected JBODs would result in data corruption.
