problematic sequence

[Kevin Wilson]

Hi,
It seems to me that the following sequence is a bit problematic; I am
running it on fedora 20:

modprobe team
teamd -d
then
kill -9 <teamdPid>
(teamdPid is of course the daemon pid)
and then:

rmmod team
gives
rmmod: ERROR: Module team is in use by: team_mode_roundrobin

but also:
rmmod: ERROR: Module team_mode_roundrobin is in use

Any ideas ? it seems to me that this is something which should not happen.
Or am I missing something ?

regards,
Kevin

I will investigate this further.
When you kill team with -9, the device stays in the system. Can you see
it by "ip link" command? Also, please try to remove if by "ip link del"
and try to remove the module again.

Indeed, killing the daemon doesn't kill the device which still uses
the kernel modules, so you can't remove them.

You need to delete the team device as well using 'ip link del' as
suggested by Jiri Pirko, then remove the modules.

Also, please try to remove if by "ip link del"
and try to remove the module again.

After "ip link del team0"
rmmod team_mode_roundrobin
rmmod team

succeed.

Regads,
