I have DRBD running with jumbo frames on several machines and it just work (albeit with 0.8.10). Check you networking. Try "ping -c1 -Mdo -s 8192 <other node>", that should tell you if you get jumbo frames to the other side or if there is a problem on the IP layer. If you get something like "From <other node> icmp_seq=1 Frag needed and DF set (mtu = <actual MTU>)", check your devices MTU and check your routing as it is actually possible to define a MTU per route. If you just get no answer or the response is too short, check the specs of your network hardware. The supported size for jumbo frames varies widely, not just between vendors but also between NIC chips from the same vendor. In some cases, even different chips support by the same driver differ in the maximum frame size. Ciao Andi
