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.
good luck

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.

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.
