<pre wrap="">Hi,
This is why, Linbit should publish in the documentation, a list of
hardware (NIC's) tested and certified as fully working.
I have seen this problem here in the list a couple of times in the
last month. It's kind of sad spend time and a lot of money in good
enterprise network hardware, and in the end things don't work as they
should.

There is no way we can do that for all the distros and kernels we support.
We can also not assume responsibility for kernel network stack bugs,
driver bugs, firmware bugs, you name it. Sorry, but what you ask for is
plain impossible. And, the underlying assumption that your hardware and
its driver is always right, and it must be DRBD that's wrong, does not
hold up in our experience. Remember broken TCP checksum offloading on
some Intel Gigabit cards?
We will double and triple check customer's hardware as part of a support
contract. We do also pinpoint individual software or hardware issues as
part of support or consultancy engagements. And we try to do what we can
in terms of alerting our user community to known hardware issues. And,
we do have hardware partners who take part in our DRBD Certified
Platform program. And that encompasses just what the name implies,
complete certified hardware platforms. Which you get full cluster stack
support on.
But we won't put up a "certified" NIC list like you are asking for. It
just makes zero sense.
Cheers,
Florian

Hi,<br>
<br>
Florian, of course everything linbit does for this community, it's
amazing, I don't really have nothing to complain and I don't know too
much company's like linbit when it comes to opensource projects. <br>
<br>
You guys are just amazing, starting from the stability, backporting,
bug correction, community support to documentation. I really don't have
nothing to complain, only to thanks.<br>
<br>
What I was trying to says its, I was not asking a list of ALL the
hardware drbd run's fine, because it should go fine everywhere. What I
was trying to says it's, imagine in the next week, I will deploy a new
cluster with drbd, I will need 10Gbit NIC's, because I have a lot of
I/O bandwidth. <br>
If there is a list with a couple of 10Gbit NIC's that works, I will
simply forward it to my manager and ask him to buy one of that ones. If
he would like to buy a shipper one, and things go wrong, don't blame on
me, or even on DRBD or Linbit... :).<br>
<br>
Would be nice to have that list, that's only.<br>
