[Samba] 答复: How to disable CTDB pulling up NICs

[Weidong]

If eth0 holds virtual IP as its secondary IP and I bring down eth0 by command "ifdown eth0", CTDB will automatically pull eth0 up. Sometime it goes wrong. The virtual IP becomes primary IP, and origin primary IP turns into a secondary IP or just missing. If the origin primary IP is missing, I have to run "ifup eth0" though CTDB has pulled eth0 up. CTDB uses “ip link set eth0 up” to pull up a NIC. I suppose “ifdown/ifup” are not compatible with “ip link set”.

10.interface actually removes/adds public IP addresses from/to interfaces.  So, without this script CTDB's public IP addresses will not work.

There is no supported way to disable the behaviour of pulling up interfaces.

Why do you want to want to disable this?
