@thinkl33t, recommended way is using dynamic-dns-update, all other ways are not recommended to use at this moment.

Yeah, I'd mark this not-a-bug. Update the documentation to mention hosts file update with failover doesn't maintain consistent state between failover servers.

Could we work around this by implementing an overlay for every commit, with the entire stack of overlays being combined with the root overlay when a save is issued?

I've finally managed to test this (apologies, we've had a super busy couple of months) and don't appear to be able to connect to the VPN anymore :(

I've put in the suggested kernel parameters for my install to disable the broken functionality. Hopefully this will keep it stable until a version with an upgraded kernel is available :)

This debian bug shows the same issue:

Its the intel broadwell one:

Its a pair of supermicro servers, each containing:

We've not had this issue since i applied the patch.

Brill, i've applied that patch and will keep an eye on it for a few days to see what happens.

The line giving the error is:

> show service dhcp-server 
hostfile-update
shared-network-name VLAN101 
  subnet 172.16.101.0/24 {
    default-router 172.16.101.254
    dns-server 172.16.101.254
    domain-name guest.example.org
    lease 3600
    range 0 {
        start 172.16.101.1
        stop 172.16.101.250
    }
  }
}

Note that this has taken down DNS on our firewall (and hence our network) a couple of times now, both annoyingly early in the morning when nobody was in to fix it.

I've implemented this in our ansible-derived vyos configuration by allowing the static addresses to be generated with the VLAN prepended and adding a system static-host-mapping for the fqdn to ip.

Actually, I managed to get this working by passing the following:

I've done a bit of fiddling with this today on a test VyOS 1.2.0-rc6, Attempting to set a custom option and pass it through to the leases file. Unfortunately I wasn't successful.

It looks like this change was made in https://phabricator.vyos.net/T726 before the python rewrite.

pdns doesn't have a built-in reload (at least not available through systemd), but i've just tested and the following works:
