[Group.of.nepali.translators] [Bug 1815101] Re: [master] Restarting systemd-networkd breaks keepalived, heartbeat, corosync, pacemaker (interface aliases are restarted)
As discussed in
https://bugs.launchpad.net/ubuntu/+source/keepalived/+bug/1819074 and
pointed out in
https://bugs.launchpad.net/ubuntu/bionic/+source/keepalived/+bug/1815101/comments/65,
as KeepConfiguration= is part of systemd nowadays, and since the
keepalived fix is available since 2.x, This should be fixed nowadays,
and I am marking the keepalived task as such.

[impact]
- ALL related HA software has a small problem if interfaces are being
managed by systemd-networkd: nic restarts/reconfigs are always going
to wipe all interfaces aliases when HA software is not expecting it to
(no coordination between them.
- keepalived, smb ctdb, pacemaker, all suffer from this. Pacemaker is
smarter in this case because it has a service monitor that will
restart the virtual IP resource, in affected node & nic, before
considering a real failure, but other HA service might consider a real
failure when it is not.
[test case]
- comment #14 is a full test case: to have 3 node pacemaker, in that
example, and cause a networkd service restart: it will trigger a
failure for the virtual IP resource monitor.
- other example is given in the original description for keepalived.
both suffer from the same issue (and other HA softwares as well).
[regression potential]
- this backports KeepConfiguration parameter, which adds some
significant complexity to networkd's configuration and behavior, which
could lead to regressions in correctly configuring the network at
networkd start, or incorrectly maintaining configuration at networkd
restart, or losing network state at networkd stop.
- Any regressions are most likely to occur during networkd start,
restart, or stop, and most likely to involve missing or incorrect ip
address(es).
- the change is based in upstream patches adding the exact feature we
needed to fix this issue & it will be integrated with a netplan change
to add the needed stanza to systemd nic configuration file

The KeepConfiguration= setting is part of systemd nowadays, so I'm closing the systemd component. Netplan does not currently make use of "KeepConfiguration=" [0] though. Marcin, could you try to place a systemd-networkd override file, e.g. in /etc/systemd/network/10-netplan-eth0.network.d/override.conf (depending on your interface name), that contains a corresponding KeepConfiguration setting and check if that makes any difference?

netplan uses the "networkctl reload/reconfigure" commands nowadays,
instead of hard restarting systemd-networkd:
https://github.com/canonical/netplan/pull/200
This change was activated in v0.104 in the Distro, which landed in Jammy
and is currently being SRUed to Focal and Impish (LP: #1964481).
Please re-open if you can still observe this issue with netplan 0.104.

[Group.of.nepali.translators] [Bug 1815101] Re: [master] Restarting systemd-networkd breaks keepalived, heartbeat, corosync, pacemaker (interface aliases are restarted)
i'm marking this as wont-fix for xenial.
i'm inclined to also mark this as wont-fix for bionic, unless there are
still people affected by this problem using bionic without some other
workaround.

Bug description:
[impact]
- ALL related HA software has a small problem if interfaces are being
managed by systemd-networkd: nic restarts/reconfigs are always going
to wipe all interfaces aliases when HA software is not expecting it to
(no coordination between them.
- keepalived, smb ctdb, pacemaker, all suffer from this. Pacemaker is
smarter in this case because it has a service monitor that will
restart the virtual IP resource, in affected node & nic, before
considering a real failure, but other HA service might consider a real
failure when it is not.
[test case]
- comment #14 is a full test case: to have 3 node pacemaker, in that
example, and cause a networkd service restart: it will trigger a
failure for the virtual IP resource monitor.
- other example is given in the original description for keepalived.
both suffer from the same issue (and other HA softwares as well).
[regression potential]
- this backports KeepConfiguration parameter, which adds some
significant complexity to networkd's configuration and behavior, which
could lead to regressions in correctly configuring the network at
networkd start, or incorrectly maintaining configuration at networkd
restart, or losing network state at networkd stop.
- Any regressions are most likely to occur during networkd start,
restart, or stop, and most likely to involve missing or incorrect ip
address(es).
- the change is based in upstream patches adding the exact feature we
needed to fix this issue & it will be integrated with a netplan change
to add the needed stanza to systemd nic configuration file

@napsty: the "workaround" (from your blog) is actually to use: - ifupdown/bridge-utils/vlan/resolvconf for network setup OR - use systemd-networkd DIRECTLY with the KeepConfiguration= option in .network file Just highlighting it here. @ddstreet, you said you would try to come up with the netplan change for KeepConfiguration. Did you have time to check on this ? (just checking).

Removing charm-keepalived since I believe no changes are needed there.
It should pick up fixes once they are available on apt archives.
** No longer affects: charm-keepalived
