Finally... Import the latest open-source ZFS version - (SPA) 28.
Few new things available from now on: - Data deduplication. - Triple parity RAIDZ (RAIDZ3). - zfs diff. - zpool split. - Snapshot holds. - zpool import -F. Allows to rewind corrupted pool to earlier transaction group. - Possibility to import pool in read-only mode. MFC after: 1 month
