Hi Mike,
The cards I’m using are HP NC522SFP Dual Port 10GbE Server Adapters with HP
BLc 10Gb SR SFP+ Fiber Transceivers. I could try running these with 1GB
Fiber cables instead of 10GB.

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.

Hi Mike,
Thanks for the quick response. 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.
Is there anything I can tweak in the drbd.conf file to get these to work.

Hi List,
Please help. I have installed drbd 8.3.5 on Open Suse 11.1 (Kernel
2.6.27.29-0.1).
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.
I have attached /proc/drbd, /etc/drbd.conf and a section from
/var/log/messages. Any pointers would be greatly appreciated.
version: 8.3.5 (api:88/proto:86-91)

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.
