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 have tried
every way i can think of to check the integrity of the network link
between the hosts and everything says they are fine except for

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.
