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>

<p class=MsoNormal>Hi List,<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>Please help. I have installed drbd 8.3.5 on Open Suse 11.1
(Kernel 2.6.27.29-0.1). <o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>I have run drbdadm create-md dbms-test on one node and
create-md dbms-test2 on the other node. I then ran drbdadm up all on both nodes.
I then ran drbdadm -- --overwrite-data-of-my-peer primary dbms-test on the
first node and the same with dbms-test2 on the other node. They then run for a
short while before stalling. I have tried older version without success and
turning the sync rate down does not make any difference. Downing the resources
and bringing back up starts the sync again but this then stalls quickly.<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>I have attached /proc/drbd, /etc/drbd.conf and a section
from /var/log/messages. Any pointers would be greatly appreciated.<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>
