Hi,
I am using the same device (/dev/sda2) for data and hash with --hash-offset
set. The hash offset is set to 4096 added to the total space used in
/dev/sda. When I verify the verity target without activating, it succeeds
and gives valid (V) status. However, when I try to load it during boot, it
gives an error with corruption at 0 and 1 block and is stuck in the boot
loop.

Is there something wrong I am doing with the hash-offset? Any help or
guidance would be really appreciated.


Thanks,
Aditya
