It takes roundabout 1-2 day's here until it will crash during sychronization. I will seriously consider moving from XFS to ext3 the follwoing days, since I have no indication that this issue will be addressed soon (unless I buy a support contract for drbd, which i cannot do). I'm quite interested how your testing goes. greets Sebastian
