I configured drbd on two 3,5TB disks. Then I created iscsi target on
it. On initiator side I created LVM on it. Then I created 6k files
500MB each.
All time drbd was connected and in UpToDate state. Then I switched
nodes. Destination become source, I checked md5 sums and on two files
I got diffrent results.

I'm using kernel 2.6.27 and drbd 8.3.10 on Debian based distribution.
I tried to run verify but few seconds after start it hanged. So I
updated drbd to version 8.3.11 and now verify is running ok, but it
will take 16h.

Any idea why did it happen and how to prevent it in the future?
