Apologies for delay on this post, my notification's bot for TrueNAS crashed.

Key Highlights:

This is a small hotpatch to address a ZFS issue that appears in specific circumstances with encrypted ZFS replication tasks. When the replication source system is updated to SCALE 22.12.3, a mismatch in indirect block size (IBS) values can cause kernel panics when an encrypted replication task attempts to receive ZFS snapshots to the destination system. See OpenZFS 2.1 Pull Request #15073 for more details.

Users are encouraged to update any TrueNAS SCALE system used as a replication source or destination to 22.12.3.3 to avoid this issue. It is also recommended to update any ZFS-based systems currently used as a replication destination.

22.12.3.3 Changelog

• NAS-122583 Crash on ZFS replication receive with different indirect block size
