Hi,
Are you still using software raid?
Have you tryed out using hardware raid?
The only time i had tryed out drbd with mdraid, well let's say, i
never will try that again, from now on, we only use areca raid
cards. Anyway, software raid it's slow, if you want to do this
thing, buy raid controllers, the best ones are areca, 3ware and
lsi it's bad, don't know all the others.
Cheers,

exaggerated the problem. when the sync hangs, the drbd module is
almost completely unresponsive. i tried doing a pause-sync and
then resume-sync thinking that it would nudge the module into
working but the commands timeout on talking to the module. i can
still cat /proc/drbd but that is about it until i take down the
network interface and drbd detects the network change. if i then
bring back up the interface, drbd detects it can talk again but
then only syncs a couple of megabytes before stalling again. i

yes, i am using software raid. i guess i didn't try changing that
during my hardware changes. i'll see if i can scrounge up some raid
controllers to test this with.
i got a hold of a few 3ware controllers and used these for the disk
array instead of the software raid. unfortunately, it still broke.
after much more experimentation and buying new hardware, i got a
things working. i did eventually try doing this on the hardware i had
using opensuse 11.2 and centos 5.4. same problems. luckily, i was
able to convince my boss to let me buy some new 10 gig nics cause
those are the only thing that didn't change. i ordered some cards
from chelsio (pcie, dual port cx4) and just got them on wednesday.
put them in, configure them, and start syncing. never hiccuped. so, i
guess for anyone else wanting to try this, avoid using 10gig pcie
intel nics.

Hi,
Can you please give me the exact Part-Number of the Cards that work
from chelsio?
And by the way the exact Model/Part-Number from intel, the ones that
don't worked?
my intel cards are the supermicro aoc-stg-i2. i can't find the card on
supermicro site any more but it is very similar to the aoc-utg-i2 which
is still listed. both just use the 82598EB chip. only difference is the
form factor.
my chelsio cards are the N320E-CXA.
