Hi,<br>
<br>
This is why, Linbit should publish in the documentation, a list of
hardware (NIC's) tested and certified as fully working. <br>
<br>
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.<br>
<br>
What do you guys think of this?<br>
<br>
Cheers,<br>
<br>

Yes you are correct we are using 10gig fibre cards. I’m not sure we
could
change them though as the fibre modules used in them cost over £400
each.<o:p></o:p></span></p>

what kind of network are you using between the two servers? this is
almost the
exact same behavior i had when i was trying to get drbd to work over
10gig
ethernet. turned out to be something in drbd didn't like something
about the
10gig cards i had. i eventually had to change my network cards. what
cards are
you using? 1gig? 10gig? have you tried other cards? that is where i
would look.<br>
