Troubleshooting Disk Space
Running out of disk space can have a severe impact on the Uyuni database and file structure which, in most cases, is not recoverable. Uyuni monitors free space in specific directories, and has configurable alerts. For more on space management, see Managing Disk Space.
You can recover disk space by removing unused software channels. For instructions on how to delete vendor channels, see Channel Management. For instructions on how to delete custom channels, see Custom Channels.
You can also check how often your custom channels are synchronized. For instructions on how deal with custom channel synchronization, see administration:custom-channels.adoc#_custom_channel_synchronization.
You can also recover disk space by cleaning up unused activation keys, content lifecycle projects, and client registrations. You can also remove redundant database entries:
spacewalk-data-fsckcommand to list any redundant database entries.
spacewalk-data-fsck --removecommand to delete them.
