Anomaly: gptzfsboot fail w/ unsupported feature "zstd_compress" aft hbsd-update as of 2022-MAR-17

[F N]

Hi,

I'm a bit confused. After performing today (2022-MAR-17, UTC 1700) a hbsd-update and a pkg upgrade it looks like the following happens after reboot:

  01: GELI Passphrase for disk0p3:

  02: Calculating GELI Decryption key ...

  03: failed to read pad2 area of primary view

  04: ZFS: unsupported feature: org.freebsd:zstd_compress

  05: ZFS: pool zroot is not supported

  06: gptzfsboot: failed to mount default pool zroot

  07: FreeBSD/x86 boot

  ...

  08: boot: _

Message number 03 seems well known and considered harmless.

Message number 04/05 puzzles me a bit.

A zpool import performed from booting the latest memstick ISO showed that the ZFS pool itself is not set to zstd compression, it's lz4 instead.

Would it be a solution to just update the gptzfsboot code with "gpart bootcode ..." ?

Any clues about what might be done best in this situation will be highly appreciated. 

Thanks

Frank

It does seem like you might need to update your bootloader. Depending
on your environment, you'll want to update with gptzfsboot (like you
mentioned (for BIOS setups)) and/or loader.efi on your ESP (for UEFI
booting).

Let me know how it goes.

Thanks,

Hello Shawn,

Thank you for your answer.

According to https://forums.freebsd.org/threads/update-of-the-bootcodes-for-a-gpt-scheme.80163/

the following steps where performed:

01: Boot from usb stick w/ latest HBSD memstick iso

      (see https://git.hardenedbsd.org/hardenedbsd/HardenedBSD/-/wikis/1%5D-Installation)

02: Provide GELI passphrase for ZFS drive

03: Select Live CD in the boot menu

04: Perform password less root login into live system

05: Verify drive data

     # gpart show | less -S

     -> identify disk name -> e.g. ada0
     -> identify partition number assigned to freebsd-boot label -> e.g. 1

06: Execute the following cmd:

     # gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0

07: # poweroff

The anomaly is now gone after starting again.

Thanks a lot for pointing in the right direction!
