Solution Verified - Updated -

Issue

  • Satellite 6 synchronized a docker repository but some downloaded file is missing, like:

    # file /var/lib/pulp/published/docker/v2/web/fc5c5240-a3cf-4def-947a-768d0a86f0e3/blobs/sha256:232aa1c3998b39ad79846afe4415af229962c62ca70c793d3b344e91336ca8bd
/var/lib/pulp/published/docker/v2/web/fc5c5240-a3cf-4def-947a-768d0a86f0e3/blobs/sha256:232aa1c3998b39ad79846afe4415af229962c62ca70c793d3b344e91336ca8bd: broken symbolic link to `/var/lib/pulp/content/units/docker_blob/3a/957415e7fc67eb36b3ad2dfcf403824d06f9761a474da21ed61e41a7b9410e/sha256:232aa1c3998b39ad79846afe4415af229962c62ca70c793d3b344e91336ca8bd'

  • Or the downloaded file is corrupted (checksum does not match the filename):

    # sha256sum /var/lib/pulp/content/units/docker_blob/3a/957415e7fc67eb36b3ad2dfcf403824d06f9761a474da21ed61e41a7b9410e/sha256:232aa1c3998b39ad79846afe4415af229962c62ca70c793d3b344e91336ca8bd
