Given that Linux with LTO-X tape drive is probably a majority system here (not 
counting
configurations without tape drives), the statement is slightly misleading. I'm 
convinced
that it is really not needed because of tape drive, server nor HBA, but it 
seems that it
is really needed because of Linux. However it is not a real problem, because 
Linux allows
to increase the block size "naturally", with the exception that you have 
limiting HBA.

More importantly however, the documentation (for Bacula 7.2 anyways) says: "The 
maximum size-in-bytes possible is 2,000,000." which contradicts the assertion that 
these can be specified as 2MB which is not the same thing. Is the documentation 
inaccurate on this subject?

I wrote 2 MB as a general recommendation over various manufacturers and software
developers, with non-written suggested value 256 KB or 512 KB as max., so please
take my 2 MB limit just loosely :o)
