![FREE SOFTWARE](/assets/categories/freesoftware.webp)
The new ZFS On Linux 0.6.4 release is now compatible with kernels up through Linux 4.0. ZFS On Linux 0.6.4 also adds new feature flags of spacemap_histogram, extensible_dataset, bookmarks, enabled_txg, hole)birth, and embedded_data.
Exciting features for ZOL 0.6.4 include asynchronous I/O (AIO) support, LZ4 compression of meta-data, fallocate() punch hole support, new bash completion support, and much more. ZOL's zpool command also has support for some new sub-commands/arguments.
More details on ZFS On Linux 0.6.4 can be found via the release announcement posted to the GitHub project page. I do have plans to do some new, multi-disk ZFS Linux file-system benchmarking, albeit I always seem to run short on time...
