Help needed rescuing my system

G

Gavilaan

Hi all,
I'm not sure what I have done but I have crashed one of my systems. I tried to update one of my jails but must have typed something wrong.
After a restart of the main system it started only halt, wrote something about a missing libz...
So I did a freebsd-update rollback and now I only got a 'invalid format' from the boot manager.

Before I do any further damage, can somebody give me some advise of best practice?


Can I just reinstall from cd without destroying the partition? Boot a rescue system and do a zfs rollback?

Any help appreciated?

Thanks
Gav

Did you perhaps update the jail to a newer version than the host?

Booting the host crashes it? Can you still boot to single mode? Try disabling the jails, and see if that will make the host boot properly.
 
No, i tried to update the jail with 12.1 to an actual version. i think i have tried to update the host 13.1 p6 to 12.2
Now the host won't start at all
 
Sorry, it's a bit complicated with the screenshot. I'm on a linuxmachine, running win7 in a virtualmachine to use the old vsphere client to get to an old esxi server ... i know
but here it is

Dear Gavilaan,
by default FreeBSD creates a boot environment at each update. At the boot prompt you can select a boot environment. I think you have to press 7 or 8. With the up/down keys you can select a previously generated environment. If that boots you can make it default by (as far as I remember)
Code: 
bectl activate NAME_OF_THE_ENV

This boot environment thing didn't work for me because i never saw the boot menu. Maybe because it took ages to connect me to the old vmware console.
I finally bootet from the iso, importet the zfs pool and did a zfs rollback to a snapshot from last night. Rebootet, all is good now.
Thanks for all your help, case closed
