----------------------------------------------------------
One option is to add a different subcommand {{ozone repair}} that supports
commands that fix problems with the cluster data. Commands that do repairs can
be added under here. A few challenges with this:
* We should make sure the node being operated on is in the stopped state. This
may be challenging since this command runs directly from the client. Some
solutions:
** Depend on RocksDB locks to fail the command if another process is using the
DB. This only works for repairs involving RocksDB.
** Add a manual prompt before commands that users must respond to before the
tool runs. This could look like {{Is the Ozone Manager stopped (y/N)?}}
* There may be code duplication between the debug and repair variants of
commands, for example if we have {{ozone debug container inspect}} and {{ozone
repiar container inspect}} that both run the same container inspector code,
just in different modes.
** This may not end up being a huge issue if we could use inheritance of util
classes to share the common code among commands.

> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Ethan Rose
> Priority: Major
>
> Currently {{ozone debug}} only offers read-only options. We have had the need
> for repair tools due to bugs in the past, and it would be good to have a
> framework and standard practice for adding these repair tools to ozone CLI.
