Re: SSD dm-crypt partition alignment

Hi.


Unfortunately this is still rather black magic to me,.. especially when
one combines LVM/MD/partitons and perhaps even the striping options in
ext-filesystems.

But AFAIK, if you just want to use _LUKS_ (guess this does not work with
plain dm-crypt devices) on partitions, and if you use a recent enough
kernel (IIRC it was 2.6.34) and recent enough cryptsetup (IIRC 1.1.3)
then the alignment should happen automatically.

The payload offset in the LUKS header is simply set accordingly.

So AFAIK you shouldn't need to use "-H 32 -S 32"...


Any better experts,... please correct me if I'm wrong.


Cheers,
Chris.
