Hi everyone,
I'm asking for assistance to fix this issue:“rmmod: ERROR: Module
openvswitch is in use”
I found unloading openvswitch. Ko, appear "rmmod: ERROR: the Module
openvswitch is in use"
lsmod see at this time::
==================================================================================================
root@ubuntu:/home/ych/zr9101/host/ovs/openvswitch-2.6.1# lsmod |grep open

Why used is not zero?,Is this a bug
Below is the steps：
1、insmod openvswitch modules
sudo modprobe gre
sudo modprobe nf_conntrack
sudo modprobe nf_defrag_ipv4
sudo modprobe nf_nat_ipv4
sudo modprobe nf_nat
sudo modprobe libcrc32c
sudo modprobe nf_defrag_ipv6
sudo modprobe nf_nat_ipv6
sudo insmod $OVS_DIR/datapath/linux/openvswitch.ko
sudo insmod $OVS_DIR/datapath/linux/vport-geneve.ko
sudo insmod $OVS_DIR/datapath/linux/vport-gre.ko
sudo insmod $OVS_DIR/datapath/linux/vport-lisp.ko
sudo insmod $OVS_DIR/datapath/linux/vport-stt.ko
sudo insmod $OVS_DIR/datapath/linux/vport-vxlan.ko
2、Initialize and start ovs
sudo rm -rf /usr/local/etc/openvswitch
sudo mkdir -p /usr/local/etc/openvswitch
sudo ovsdb-tool create /usr/local/etc/openvswitch/conf.db ./vswitch.ovsschema
#start configuration database
sudo ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock \
--remote=db:Open_vSwitch,Open_vSwitch,manager_options \
--private-key=db:Open_vSwitch,SSL,private_key \
--certificate=db:Open_vSwitch,SSL,certificate \
--bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert \
--pidfile --detach
#initialize the database
sudo ovs-vsctl --no-wait init
#start the main Open vSwitch daemon
sudo ovs-vswitchd --pidfile --detach --log-file=/var/log/ovs-vswitchd.log
3、add br and add port
sudo ovs-vsctl add-br br0
sudo ovs-vsctl add-port br0 ens39
sudo ifconfig ens39 0
sudo ifconfig br0 192.168.230.130/24
4、del port and del br
sudo ovs-vsctl del-port ens39
sudo ovs-vsctl del-br br0
5、Stop the Open vSwitch daemons
kill `cd /usr/local/var/run/openvswitch && cat ovsdb-server.pid
ovs-vswitchd.pid`
6、rmmod openvswitch fail
sudo rmmod openvswitch.ko
appear "rmmod: ERROR: the Module openvswitch is in use"
