Description Rumen Palov 2021-06-09 16:02:29 UTC

Hello all,

recently we have updated our server from FreeBSD 11 to FreeBSD 13.0.

Month later we have to update it to latest FreeBSD 13.0 source.

After make "buildworld kernel" we are not able to boot OS, eg. we are not able to complete FreeBSD Update from source procedure in single mode. 

Booting from livemedia and update gptzfsboot( gpart -p ) code from /usr/obj/usr/src/amd64.amd64/stand/i386/gptzfsboot/gptzfsboot  is the only way and solution to have proper boot. 

Updating gptzfsboot from OS disk /boot/gptzfsboot does not solve the issue, because we do no have installworld executed yet. 

Cheers

After make installworld  in single user, the OS does not boot because of zfsloader LUA error :)

What happens actually. 

The server was upgraded from  rev. 3821585 --> 3837207( make buildwrold kernel ).

At the step of rebooting for single mode ( reboot command ) - the server stays very long at last shutdown stage "Syncing disk .. vnodes .. " more than 40 minutes. 

At some point of time we power off the server and then power it back on. My suspicions are that exactly that step breaks the zfs somehow.

The later steps are described in the first post. 

Finally we were unable to fix the issue and the server was reinstalled.
