Hi all,

I have issues with a xen/drbd setup. The problem here is, that the NIC
between the both primary/primary is down for a second once in a while.

Jul 29 00:07:07 xen1 kernel: bnx2: eth1 NIC Copper Link is Down
Jul 29 00:07:08 xen1 kernel: bnx2: eth2 NIC Copper Link is Down
Jul 29 00:07:10 xen1 kernel: bnx2: eth1 NIC Copper Link is Up, 1000Mbps full duplex, receive & transmit flow control ON 
Jul 29 00:07:10 xen1 kernel: bnx2: eth2 NIC Copper Link is Up,1000Mbpsfull duplex, receive & transmit flow control ON

Hence the storage repository can't be accessed any more and so on.

At the moment I can't say whether it is a flaw in the driver or HW or
cable or whatever. 

Does some-one had similar problems (with bnx2)? What is the time limit
for drbd when a link dies? Does it makes sense to increase that limit?

Thanks for input!

Greetings,

Oliver
