FreeBSD install on zfs raid 1

S

Solaris

Hello, I am following this guide: http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/Mirror, but when finished the installation and booting to fresh installed it throw error:

Code: 
can't exec getty '/usr/libexec/getty' for port /dev/ttyv0
can't exec getty '/usr/libexec/getty' for port /dev/ttyv1
can't exec getty '/usr/libexec/getty' for port /dev/ttyv2
can't exec getty '/usr/libexec/getty' for port /dev/ttyv3
can't exec getty '/usr/libexec/getty' for port /dev/ttyv4
can't exec getty '/usr/libexec/getty' for port /dev/ttyv5
can't exec getty '/usr/libexec/getty' for port /dev/ttyv6
can't exec getty '/usr/libexec/getty' for port /dev/ttyv7

What would be the problem? I am really confused because this is the second attempt after I was following another tutorial. I am installing FreeBSD 8.1 amd64.
 
How are your mountpoints for the zfs filesystems? That sounds like /usr is not mounted where it should be.
 
Hmm after hard reset it seem all zfs mountpoints and pool gone, zpool status -v and zfs list says "no datasets available", only gmirror left in :

Boot into Fixit and do:
# mkdir /boot/zfs

# kldload /mnt2/boot/kernel/opensolaris.ko

# kldload /mnt2/boot/kernel/zfs.ko

# zpool import -f -R /altroot poolname

That should mount your pool under /altroot except for datasets (filesystems) that have mountpoint set to legacy, root file system for example.
 
Thanks, now it showed up, here it is :

Is there anything wrong ?
 
Check the real mountpoints with:

# zfs get mountpoint

What you are seeing in Fixit are the altroot mountpoints (because you specified -R option for zpool) that are always temporary assignments and disappear on reboot.
 
Code: 
NAME                           PROPERTY    VALUE                          SOURCE
zroot                      mountpoint  legacy                         local
zroot/tmp                  mountpoint  /altroot/tmp                   local
zroot/usr                  mountpoint  /altroot/usr                   local
zroot/usr/home             mountpoint  /altroot/usr/home              inherited from zroot/usr
zroot/usr/ports            mountpoint  /altroot/usr/ports             inherited from zroot/usr
zroot/usr/ports/distfiles  mountpoint  /altroot/usr/ports/distfiles   inherited from zroot/usr
zroot/usr/ports/packages   mountpoint  /altroot/usr/ports/packages    inherited from zroot/usr
zroot/usr/src              mountpoint  /altroot/usr/src               inherited from zroot/usr
zroot/var                  mountpoint  /altroot/var                   local
zroot/var/crash            mountpoint  /altroot/var/crash             inherited from zroot/var
zroot/var/db               mountpoint  /altroot/var/db                inherited from zroot/var
zroot/var/db/pkg           mountpoint  /altroot/var/db/pkg            inherited from zroot/var
zroot/var/empty            mountpoint  /altroot/var/empty             inherited from zroot/var
zroot/var/log              mountpoint  /altroot/var/log               inherited from zroot/var
zroot/var/mail             mountpoint  /altroot/var/mail              inherited from zroot/var
zroot/var/run              mountpoint  /altroot/var/run               inherited from zroot/var
zroot/var/tmp              mountpoint  /altroot/var/tmp               inherited from zroot/var
 
Hmm that didn't quite work. I assumed # zfs get mountpoint would show the actual mountpoints the system would use when booted. I don't have a system to test the same procedure on right now... Can you see if /altroot/usr/libexec/getty exists?
 
Which one didn't quite work? My setup? Or the tutorial?

Strange after again hard reboot, now only tmp/ usr/ var/ shows up, before I perfectly sure there is complete directory of all defined mountpoints and getty was there too. Yes I was redid your #4 steps, and weird thing is all mountpoints still intact on get mountpoints.
 
I meant the command on post #6 but your mount points actually look fine because the altroot property is not a property of a dataset but the pool.

Can you see if there are any error messages in /altroot/var/log/messages or in any of /altroot/var/log/dmesg.*

It went havoc, there was no files in var :(, it seem I forgot to set checksum=fletcher4 on zroot, after retrying from scratch all work fine, thanks kpa for the help :).
 
Just for the record, ZFS runs just fine with fletcher2, the default checksum algorithm. There is really no need to change it.
