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4 +As of today (2024), some of this information may be out of date as support for ZFS under linux has improved considerably.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.

47 47  Quick post on installing ZFS as a kernel module, not FUSE, on Debian GNU/Linux. The documents already exist for getting this going, I'm just hoping to spread this to a larger audience, in case you are unaware that it exists.

51 51  **UPDATE (May 05, 2013)**: I've updated the installation instructions. The old instructions included downloading the source and installing from there. 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:

65 65  --**A word of note:** the manpages get installed to /share/man/. I found this troubling. You can modify your $MANPATH variable to include /share/man/man8/, or by creating symlinks, which is the approach I took:--

67 -{{{# cd /usr/share/man/man8/

76 76  It is stable enough to run a ZFS root filesystem on a GNU/Linux installation for your workstation as something to play around with. It is copy-on-write, supports compression, deduplication, file atomicity, off-disk caching, --encryption,-- and much more. At this point, unfortunately, I'm convinced that ZFS as a Linux kernel module will become "stable" long before Btrfs will be stable in the mainline kernel. Either way, it doesn't matter to me. Both are Free Software, and both provide the long needed features we've needed with today's storage needs. Competition is healthy, and I love having choice. Right now, that choice might just be ZFS.
