https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264174 Bug ID: 264174 Summary: Use of redaction bookmarks or redacted datasets on a boot pool renders the pool unbootable Product: Base System Version: 13.1-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: astralblue@gmail.com src/stand/libsa/zfs/zfsimpl.c defines features_for_read, which contains a s= et of whitelisted zpool features. If any other read-only-incompatible feature= is active on a boot pool (that is, enabled and in use) the boot loader will fa= il to boot from the pool. With ZoR, it is easy to shoot oneself in the foot by accidentally activatin= g a read-only-incompatible feature. Currently these include redaction_bookmarks and redacted_datasets, activated by creating redaction bookmarks and receiv= ing redacted send streams. It would be nice if zfs redact and zfs receive commands checked the feature activation and warned the (unsuspecting) user about this if the pool is a b= oot pool. Suggested message for zfs redact: WARNING: A redaction bookmark was created on a boot pool. Currently FreeBSD cannot boot from a pool with redaction bookmarks or redacted datasets. To undo this change, run: zfs destroy zroot/test/base#redacted To identify all redaction bookmarks and redacted snapshots on the pool, run: zfs get -rHp -t bookmark,snapshot -o name redact_snaps zroot --=20 You are receiving this mail because: You are the assignee for the bug.=
