I have three team interfaces:
- sw1 and sw2, both are three-NIC lacps
- and an activebackup called team0 (I'm open to better naming suggestions
:) on top of sw1+sw2.
Here is how vlan interface teardown looks like using the unstacked sw1
interface:
[root@vc1n3 ~]# systemctl start teamd@sw1
[root@vc1n3 ~]# ip l s sw1 up
[root@vc1n3 ~]# ip link add link sw1 name lan.246 type vlan id 246
[root@vc1n3 ~]# ip l s lan.246 up
[root@vc1n3 ~]# systemctl stop teamd@sw1
[root@vc1n3 ~]#
Everything went fine, both sw1 and lan.246@sw1 are now gone.
Now let's try this with stacked team interfaces:
[root@vc1n3 ~]# systemctl start teamd@sw1 teamd@sw2
[root@vc1n3 ~]# systemctl start teamd@team0
[root@vc1n3 ~]# ip l s team0 up
[root@vc1n3 ~]# ip link add link team0 name lan.246 type vlan id 246
[root@vc1n3 ~]# ip l s lan.246 up
[root@vc1n3 ~]# systemctl stop teamd@team0
… and it freezes. I can't tell you what the state of the network interfaces
is, because running 'ip link show' also freezes. The teamd process becomes
unkillable. Only thing left to do now is to hard reset the system, cause I
can't do a proper shutdown in any shape or form.
Looks this might be fixed with the Xin Long's patch I just applied. Try
the current git please.
