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 during a ping
flood there will be a few out of a couple h
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.
