When the mode of a bond is changed, and the bond is restarted after that, the new mode is not correctly set for the bond. Error message: /lib/rc/net/bonding.sh: line 48: echo: write error: Operation not permitted The reason is, that the bond is taken down totally, when stopped. Reproducible: Always Steps to Reproduce: 1. Configure a bond in /etc/conf.d/net: config_bond0="192.168.127.1/32" mode_bond0="active-passive" miimon_bond0="100" slaves_bond0="eth2" 2. Start the bond and check mode # /etc/init.d/net.bond0 start # cat /sys/class/net/bond0/bonding/mode active-backup 1 3. Stop the bond: # /etc/init.d/net.bond0 stop 4. Change mode in /etc/conf.d/net: mode_bond0="active-rr" 5. Start the bond and check mode # /etc/init.d/net.bond0 start # cat /sys/class/net/bond0/bonding/mode active-backup 1 Actual Results: When the bond is started again, the mode is not changed and stays with the configuration of the first start. Expected Results: The mode of bond should be configured to the settings in /etc/conf.d/net.
Created attachment 242525 [details, diff] Take bond completly down, when stopped. When using the sysfs interface for bonding, the best practice should be to set 'options bonding max_bonds=0' in /etc/modprobe.d/bond.conf. This patch then takes a bond down and destroys it, when sysfs is used.
Looks good, we'll include it. Thanks again for the patch.
