I see. Well, originally I had pre-up and post-down scripts, but people
complained that it didn't work because bonding fails if the master
interface is not up (see attached email). I see that you work around
this by adding "pre-up ifconfig bond0 up" to the iface stanza. I guess I
can bring the interface up automatically in a pre-up script.

Hello,

Little question to your ifenslave-2.6 package.




get the error:

server:/etc/network# ifup bond0
Illegal operation: the specified master interfaces 'bond0' is not up.
Illegal operation: the specified master interfaces 'bond0' is not up.
run-parts: /etc/network/if-pre-up.d/ifenslave exited with return code 1




if-down.d and it starts working.

Cheers,
Andreas

Shouldn't the enslave of the slaves interfaces happend after the bonding device is up? Also I think the slaves should be detached before the bonding device goes down. Currently you do this in if-pre-up.d and if-post-down.d. But in this constellation I always After this the bond0 get's up, but without the physicall interfaces enslaved. For me I have simply moved if-pre-up.d/ifenslave to if-up.d and if-post-down.d/ifenslave to
