Preliminary analysis at this point appears to indicate that it is a
REALLY bad idea on an LTO drive to have bacula-sd's configured max block
size not an exact multiple of LTO's native 1024-byte block unit.

So, someone recently observed you could set max block size up to 2000000
on an LTO4 drive, with 2000000 being a Bacula internal limit.  Well, and
so you can; but don't use 2000000.  Use a multiple of 1024.  I've reset
mine to 1024000 and I'm getting a sustained 72.5MB/s write to a HP
external LTO4 on an LSI Logic Falcon series SAS-2 controller.  (SAS2008,
specifically.)
