2 +These pages were retrieved from archive.org as the original blog has gone dark. I've preserved them as I found the information both clear and useful when I was first learning about managing the ZFS file system.

4 +As of today (2024), some of this information may be out of date as support for ZFS under linux has improved considerably. However, the basic administration commands remain the same.

45 45  **UPDATE (May 06, 2012)**: I apologize for mentioning it supports encryption. Pool version 28 is the latest source that the Free Software community has. Encryption was not added until pool version 30. So, encryption is not supported natively with the ZFS on Linux project. However, you can use LUKS containers underneath, or you can use Ecryptfs for the entire filesystem, which would still give you all the checksum, scrubbing and data integrity benefits of ZFS. Until Oracle gets their act together, and releases the current sources of ZFS, crypto is not implemented.

At the time, that was all that was available. Since then, the ZFS on Linux project has created a proper Debian repository that you can use to install ZFS. Here is how you would do that:
