I have an amanda server and an amanda client, both run latest Debian and amanda.
Both have 2 GBit/s NICs each and they are bonded via linux bonding module, mode 4 (LACP). For sure there is also a trunk defined on the switch ports. The bonding works fine when I test with several rsync or scp copies. Amanda/amdump seems to only saturate one GB port of the client. I edited the default interface definition "local" in amanda.conf already to say 2Gbps (I know that is more of a calculation parameter). Does mode 4 allow to use the full 2 Gbps with one client MAC only? I know that lower modes decide how to distribute traffic based on MACs but I am unsure about mode4. Does someone successfully use bonding with amanda like I plan to?
