hrm. i thought i had heard of someone using drbd over 10 gig with
netxen cards. i went looking for a few minutes and didn't find anything
though. my recommendation would be try newer drivers either through
compiling the drivers for you existing kernel or using a newer kernel.
i don't have details on how to do that for your cards cause i have
never used any 10 gig from hp or netxen. other than that, my only
recommendation is new nics.<br>
<br>
good luck<br>

<p class="MsoNormal">nothing i tried tweaking in drbd.conf worked.
the only thing
that did was changing the 10gig interfaces. what cards are you using? i
was
using ones with an intel chip. the cards that i did get it to work with
were
from chelsio. in my previous thread on the list, someone mentioned that
they
had neterion cards working.<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.</span><o:p></o:p></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>
