Troubleshooting Disk Space

Running out of disk space can have a severe impact on the SUSE Manager database and file structure which, in most cases, is not recoverable. SUSE Manager monitors free space in specific directories, and has configurable alerts. For more on space management, see Disk Space Management.

Generally, container volumes share space with the host filesystem. When the btrfs filesystem becomes full, it can prevent you from deleting files. To resolve this, you can add a small amount of storage temporarily to the filesystem using the btrfs device add command. This will allow you to delete files to gain space for further filesystem maintenance. When done with the maintenance, you can remove the temporary storage with btrfs device delete.

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:

Procedure: Resolving Redundant Database Entries

Use the spacewalk-data-fsck command to list any redundant database entries.
Use the spacewalk-data-fsck --remove command to delete them.
