ZFS on Linux (OpenZFS), the open-source implementation of the ZFS file system and volume manager, has released an important update, version 2.2.1. Users are recommended to update to this release, especially if they are currently running 2.2.0, to avoid the block cloning bug. Users running older versions of ZFS are unaffected by this issue.

Changes in version 2.2.1 include:

  • Disabling block cloning by default to fix a block cloning bug that could result in data corruption
  • Adding a tunable to disable BRT support
  • Auto-generating changelog during configure for packaging
  • Compatibility updates for Linux 6.6
  • Various bug fixes and optimizations

Supported Platforms:

  • Linux: compatible with 3.10 - 6.6 kernels
  • FreeBSD: compatible with releases starting from 12.2-RELEASE
