Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

I thing that hit me with such a setup (active-passive-bond with two
switches for the cluster in my case): Its great to fail over when one
switch fails completely due to power-loss or something like that. But
When the switch fails software-wise (failure or misconfiguration) the
network-links will still be up, so no fail-over from the bond is
happening. But no data will go around...

Have fun,
