"geli init -a hmac/sha256" does not work properly

[Cem Kayali]

Hello all there!...

Once i would like to enable disk encryption with geli approcah, i 
noticed following problem:



CASE 1 | SUCCES
-----------------------------------------------------------------------------------------------
geli init -b -e aes -l 256 -s 4096 /dev/ad4s1
       
This initializes geli without problem, and then once you run 'bsdlabel 
-w /dev/ad4s1' it goes as expected.
   
      
CASE 2 | FAIL
-----------------------------------------------------------------------------------------------
geli init -b -e aes -l 256 -s 8192 /dev/ad4s1
         
This initializes geli with a warning message 'sector size is bigger than 
the page size' and also 'bsdlabel -w /dev/ad4s1' fails with following 
notice: 'bsdlabel: /dev/ad4s1 read: invalid argument'
  
     
CASE 3 | FAIL
-----------------------------------------------------------------------------------------------
geli init -b -e aes -l 256 -s 4096 -a hmac/sha256 /dev/ad4s1
     
This initializes geli with a warning message 'sector size is bigger than 
the page size' and also 'bsdlabel -w /dev/ad4s1' fails with following 
notice: 'bsdlabel: /dev/ad4s1 read: invalid argument'
   
     
    

In short, if i enable 'data integrity verification' or if i increase 
'sector size', 'bsdlabel -w' gives error message.



I thank you in advance for advises.
