    I have done:

    dd if=/dev/zero of=/backups/archive bs=1048576 count=22000

    and:

    cryptsetup resize /dev/mapper/archive

    and but I get:

    resize2fs /dev/mapper/archive
    resize2fs 1.41.14 (22-Dec-2010)
    The filesystem is already 5631743 blocks long. Nothing to do!

    Please help on how to resize a container created with the following:

    dd if=/dev/zero of=/backups/archive bs=1048576 count=22000
    losetup /dev/loop1 /backups/archive
    cryptsetup luksFormat /dev/loop1
    cryptsetup luksOpen /dev/loop1 archive
    mkfs.ext2 /dev/mapper/archive

    The above along with e2fsck before resize2fs worked. I accidently dd appeneded to a different file which is why it wasnt working. Really sad that no one bothered to help Stackoverflow and this forum are both kinda sucking

    It looks like you're upset because we're not psychic and thus unable to figure out that what you were doing didn't work because of something you didn't tell us. I apologize for the whole forum.
