I don't see why you want to distinguish between "user-space" and
"kernel-space" SDP. I assume by the former you mean using libsdp
together with the kernel module ib_sdp. While this method uses a syscall
interface to ib_sdp rather than direct "in-kernel operations" like drbd,
both methods actually use the basic code in ib_sdp.
But anyway, this discussion doesn't lead to a solution of the
problem. In my understanding, SDP support is an advertised feature of
DRBD, and I bought Infiniband hardware just because of that. All I want
now is some assistance in debugging this. I believe there are a number
of other users who would be happy if DRBD over SDP were working. If SDP
support is not a supported feature anymore, it should be clearly stated
though.
Thanks,
