    Bug fix: attempt to avoid hangs when creating blockstores on large SSDs. · a670b802

    At least I think the problem is that we are doing inadvertent TRIM
    operations on large (480GB) SSDs. For one, when creating an ext4
    filesystem on such a blockstore, we specify "nodiscard". I toyed
    with the idea of turning off "issue_discards" for the lvremove
    operations when a blockstore is destroyed, but that led to old
    metadata being seen when the blockstore was re-created. That led
    to the last change, which was to force metadata zeroing when we
    do an lvcreate of a blockstore.
