[jira] [Commented] (HDDS-8100) Support repair commands from ozone CLI

["Ethan Rose (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDDS-8100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17697580#comment-17697580 ] 

Ethan Rose commented on HDDS-8100:
----------------------------------

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)?}}

> 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.
