Bug#511164: It'd be nice if mdadm -G --help mentioned "max" argument to -z switch

[Christian Hudon]

Package: mdadm
Version: 2.6.7-1
Severity: wishlist

It'd nice if the help printed out when running mdadm -G --help also 
mentioned the "max" parameter that can be passed to the -z option. Just 
a one-line mention would be fine. (I know it's already in the manpage... 
I found it trying to come up by hand with the right block size to pass.) 
Because otherwise reading the help text gives the impression that you 
*have* to specify the maximum size manually, which isn't the case with 
the "max" argument. Also, I suspect said "max" argument is passed to -z 
a fair bit more often than a numerical value. (It's certainly much less 
error-prone).

Thanks,

  Christian
