Description Jose Plans 2006-07-21 14:40:29 UTC 
initscripts-7.93.24.EL-1.1

/sbin/ifdown does not invoke "/sbin/ifenslave -d" on a bonded interface member.
If we bring down this interface : ifdown eth2, we can't bring it back up by any
means.

This produces a situation where the interface becomes unusable without bouncing
the whole bond. This situation is suitable for enterprise high-reliability
deployments.

This bug is also present in RHEL3 initscripts (yes, I know it's too late, but I
thought I'd mention it).

The attached patch allows you to :
  - remove a slave from an active bonding and being able to retach it to either
the old one (preserving its configuration) or to assign other configuration
making it active (manually).
  - detach the slaves from the bonding if we ask to bring down the bonding itself.

Let me know if there's need for more details,
   jose

Comment 3 Bill Nottingham 2006-07-21 14:56:32 UTC 
Why check with ip - why not just unilaterally remove the slaves?
