>Originator:     Chris Nehren
>Release:        10.0-STABLE
>Organization:
>Environment:
I can't `uname -a` because I can't boot the afflicted system. It's
10.0-STABLE after the new Delphix ZFS feature flags went in.
>Description:
Eager sysadmins like to upgrade their ZFS pool versions and then reboot.
This can cause problems if one doesn't update the gpart bootcode. I
presently have a workstation I can't boot because I didn't realize I
needed to do this. Putting this information in UPDATING for every
relevant feature flag change would save people like me rather a lot of
time and frustration.
>How-To-Repeat:
Install 10-RELEASE with ZFS root. Upgrade to 10-STABLE after the new
feature flags from Delphix went in. Reboot. Witness gptzfsboot being
unable to import the bootpool.
>Fix:
A mailing list post
(http://lists.freebsd.org/pipermail/freebsd-current/2014-January/047639.html)
suggests upgrading the bootcode should be sufficient. This needs to get
into UPDATING because foregoing this step leaves a system not bootable.
