FreeBSD errors after upgrading to freebsd-13.0-BETA2 on ZFS
1- reboot and shutdown, hang and take a long time to sync "All buffers synced"
2- ping -c 3 http://google.com / "ping: UDP connect: No route to host"
3- pfctl -f /etc/pf.conf / "pfctl: DIOCADDRULE: Invalid argument"

On general the upgrade was success and smooth form Freebsd 12.2 to Freebsd-13.0-BETA2 and Freebsd-13.0-BETA3 with OpenZFS 2.0

Looks like you have issues with your network adapter. Which network card do you have and what driver detected it? I would also suggest turning off PF for testing, as it looks like you're doing something there that causes it to fail.

The error pfctl -f /etc/pf.conf / "pfctl: DIOCADDRULE: Invalid argument" is resolved after upgrading to FreeBSD 13.0-BETA3

The error ping -c 3 http://google.com "ping: UDP connect: No route to host" persist even after turning off PF.

For the same VM configuration but with FreeBSD 12.2-RELEASE, there is no errors.

My setup is on a VM with a network adapter : Paravirtualized Network - virtio-net
Code: 
vtnet0: flags=8863<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=4c07bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWTSO,LINKSTATE,TXCSUM_IPV6>
        ether 08:00:27:5e:80:bc
        inet 10.29.79.239 netmask 0xffffff00 broadcast 10.29.79.255

        status: active
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
 
The ping(8) command doesn't accept URLs as an argument, only IP addresses or hostnames. Besides that, ping(8) uses ICMP, not UDP.

Thanks for the reminding, but it just a typo from copy&paste.

I suspect you have an error or issue with /etc/resolv.conf. Verify your DNS settings.

By the way this DNS settings conf work on freebsd 12.2-Release.

My config now with Freebsd-13.0-BETA3
cat /etc/resolv.conf

The ping command doesn't work with hostnames as an argument, but as IP addresse ping the command work fine.
Please look at the png file attached

What does host www.google.com return? Or drill www.google.com? And post the output from netstat -rn. As text please, pictures are difficult to copy/paste.

Ok, so name resolving (DNS) works, that's good. Your default gateway looks odd though. While it's technically possible to use any IP address within a subnet, it's more common for the .1 or .254 addresses being used as a gateway address. The message about UDP is odd too, as I said, ping(8) uses ICMP, not UDP.

This appears to be a VM? How is it connected? What's the host running? Which virtualization software?
 
FreeBSD Success and smooth upgrade form Freebsd 12.2-RELEASE to Freebsd-13.0-RELEASE-p0 with OpenZFS 2.0
1- reboot and shutdown, don't hang and take a normal time to sync All the buffers and vnodes, considering the configuration of the Server VM.
2- ping -c 3 google.com "ping: UDP connect: No route to host", persist with the error, even it work with the same config on Freebsd 12.2-RELEASE

The All-in-one (Freebsd, PostgreSQL, PgPool-II, Nginx, Samba, ...) setup for my server work fine and tested without problems.

Thanks for all and the Administrator SirDice for his attentions to help the FreeBSD Community.

Happy Freebsd-13.0-RELEASE.
