I have a dual primary drbd setup with "sndbuf-size 0" set on both nodes, however one node has two gigabytes of memory, and the other has eight. Nearly all of the memory is used by the buffer cache due to the target caching. If the node that has 2gb is the currently "active" (as in actual traffic is only done to one of them), the attached kernel message is triggered during heavy I/O operations from the initiator. I have not been able to replicate this when the 8gb node is active - could we conclude that 2gb is too little in such a setup?<br>
