OK, after further tests, "WRITE SAME" (which fails) seems to be the root cause.
Here is a workaround, to launch at boot time :
find /sys/devices/ -name max_write_same_blocks -exec sh -c 'echo 0 > {}’ \;
So, kernel should be improved to detect "WRITE SAME" compliance more friendly.
Or DRBD should include a patch to ignore such errors.
But sounds like that work should be done at kernel side.
