[#modprobe bonding do not provide "bond0" value in bonding_masters file]
Hello, since few years i use bonding under systemd with home made service and configuration files
just with net-firewall/iptables , sys-apps/iproute2 , net-misc/ifenslave and modprobe.
Since last upadte (today) of my system, have no bond0 device at boot....grrrrr
Before: when you start module bonding (manually, idem if auto at boot)
you have with this command
# ls /sys/class/net
the listing of all network devices with bond0...
---> bond0 bonding_masters eno1 enp2s0 enp8s0 lo sit0
now have only --> bonding_masters eno1 enp2s0 enp8s0 lo sit0
modprobe bonding create a file /sys/class/net/bonding_masters
and(?) a symlink /sys/class/net/bond0
i think in bonding_masters we have a bond0 value, today this file is empty...
the only work around i found is to manually inject bond0 in bonding_masters file
and only after, i can manually start my systemd bonding service
i found this tips in this good topic https://backdrift.org/manage-linux-bonding-without-ifenslave-using-sysfs
i love and use gentoo since 15 years ... but since 2 years ... |
