− | + | One of the first OpenZFS projects was a new versioning system called "feature flags" which tags on-disk format changes with unique names. The system supports both completely independent format changes, as well as format changes that depend on each other. A pool's on-disk format is portable between OpenZFS implementations as long as all of the feature flags in use by the pool are supported by both implementations. | |
+ | |||
+ | All OpenZFS implementations now support feature flags and regularly port features between them to remain compatible. | ||
Upgrading a pool's feature flags is a one way process. If you enable new feature flags on your pools, you cannot use them with any previous version of OpenZFS on OS X unless that version also supports all of the flags you have enabled. In general, you can only use a given pool with a particular OpenZFS distribution (including those on other platforms) if that distribution supports all of the feature flags enabled in the pool. | Upgrading a pool's feature flags is a one way process.
