Subject: [PATCH] teamd: do no remove the ports on shutdown with -N
|
|
|
|
With -N, teamd currently leaves the team device in place on shutdown,
|
|
as it's supposed to, but it removes all the ports. This severely limits
|
|
usefullness of the option, because it's still impossible to replace
|
|
the daemon with another one without disrupting connectivity.
|
|
|
|
One use case where this is important is the handover from initrd to real
|
|
root, when a team device was used to provide connectivity to a network
|
|
root filesystem:
|
|
|
|
Systemd's isolation of switch-root.target stops NetworkManager.service and
|
|
then terminates its kids, including teamd. The real NetworkManager.service
|
|
would eventually catch up and restart it, but there's a short period when
|
|
team ports are removed which is not great if we're booting off that device.
|
|
Also, it may be that ports come up in different order, causing team to get
|
|
a different MAC address, which will invalidate the DHCP lease we got
|
|
beforehands and screwing up L3 addressing.
|
|
|
|
Let's not flush the ports when -N is used.
