sysctl: unknown oid 'vfs.zfs.bclone_enabled'13.2-RELEASE is most likely also affected: OpenZFS issue - 15526; though it seems that this bug is hard to trigger.

doneYou jumped from pre-OpenZFS (12.4) to OpenZFS 2.2 (14.0). If you haven't upgraded your zpools at all, then I think your zpools should be still on the old version 28 (=pre Feature Flags era). If your BEs are created as per default then you should be able to revert to 12.4 AFAIK
