ZFS Feature Flag Removal

Executive Summary

  • ZFS xattr_compat feature flag removed

How to tell if I’m impacted by this change

  • Users who created or upgraded a pool using a TrueNAS SCALE nightly build dated between June 29, 2021 and July 15, 2021 are impacted by this change.
  • Users who have manually set xattr_compat=all on a dataset and written an xattr are impacted by this change.
  • If unsure, you can verify a pool’s status of the xattr_compat feature flag. If the flag is in the active state, you are impacted by this change.


How to resolve this if I am impacted

  • Any pool that has had the feature active, must be backed up and restored into a pool created on a version of ZFS without the feature. For details on how to perform data protection procedures, please refer to the TrueNAS SCALE Data Protection documentation.
