> If you suffer a disk failure, all affected tablets will be tombstoned upon rereplication. However, these tombstones still participate in the pre-flight check done by {{kudu fs update_dirs}}, which means that they'll prevent the removal of the failed disk (unless {{--force}} is used).
> The invariant here is that a tombstoned tablet doesn't have a persistent {{data_dir_group}} in its superblock, so it'll never have a working in-memory data dir group, which means it'll always fail the pre-flight check.
