Comment 47 for bug 1337873

Hi all

I upgraded ifenslave and ifupdown to 2.4ubuntu1.2 and 0.7.47.2ubuntu4.3 respectively. After reboot, the bonding did not come up correctly; mtu were set wrongly (default to 1500), default gateway was not set, nameserver information were not set in /etc/resolv.conf

After downgrading ifupdown to 0.7.47.2ubuntu4 and rebooted the server, everything came up fine again.

Since the server is in storage cluster server pool and could not hold on to it for long. I downgraded the ifupdown package and joined the production pool.
