I am using cryptsetup to work with encryption. Everything is ok and working nice. However I have an issue and I don't know how to solve it. Well, the kernel is loaded, same for the ramdisk. In the ramdisk I use *cryptsetup luksOpen blabla*.. and then I use *mount /dev/mapper/enc /media/root*. Then I switch_root to /media/root. Everything works normally. Inside the switched_root system, I do e2fsck or dumpe2fs on /dev/sda2, where sda2 is that encrypted partitionand it returns: bad superblock and stuff like this.In the ramdisk I had the /dev/mapper/enc device, but in switched_root system I don't have it. I only have /dev/mapper/control. So can anyone tell me how I can manipulate my sda2 device in the switched_root environment ?

Hello evertybody. I
        am using cryptsetup to work with encryption. Everything is ok
        and working nice. However I have an issue and I don't know how
        to solve it. Well, the kernel is loaded, same for the ramdisk.
        In the ramdisk I use cryptsetup luksOpen blabla.. and
        then I use mount /dev/mapper/enc /media/root. Then I
        switch_root to /media/root. Everything works normally.

        

      

Inside the switched_root
        system, I do e2fsck or dumpe2fs on /dev/sda2, where sda2 is that
        encrypted partition and it returns: bad
        superblock and stuff like this. In the ramdisk I had
        the /dev/mapper/enc device, but in switched_root system I don't
        have it. I only have /dev/mapper/control. 

      So can anyone tell me how I can manipulate my sda2
        device in the switched_root environment ?

        Thanks, Kostas.
