The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.
To ensure that errata mapping is maintained for all versions of each package, Spacewalk mirrors all available versions of all available packages. As a result, the storage requirements for a Spacewalk server can be significant, based on the number of major versions and architectures you chose to support. As a guide, the Oracle Linux binary repositories require approximately 50GB for each architecture, with an extra 30-40GB required for source packages.
Packages are never removed from Oracle Linux repositories, so the space required for each repository only ever increases. You should actively monitor the available disk space on the Spacewalk server.
