Additionally: If its two direct links dedicated to your storage network, there is no reason going active/backup and discarding half of the available bandwidth. Just use one of the real modes, balance-rr, balance-xor, 802.3ad or maybe balance-alb. But the last one is only needed when there are components involved that don't understand the bonding. Which is not the case when its just two machines directly connected... Arnold -- Dieses Email wurde elektronisch erstellt und ist ohne handschriftliche Unterschrift gültig.
