Hi,<br>
<br>
I have 2 Sun xFire 4140 servers, each with 4x 74GB SAS HDD (don't know<br>
the manufacturer by heart). I used the hardware raid controller to<br>
create 2x Raid 1 Partition out of those 4 disks. One of those partitions<br>
is for the OS only and one is for DRBD only.</blockquote><div><br>Hi,<br><br>Try using some combination of the following in the disk section of drbd.conf, if you're not already:<br><br>no-md-flushes;<br>no-disk-flushes;<br>
no-disk-barrier;<br><br>I find that usually they're needed to achieve proper speed with DRBD on a hardware raid controller.<br><br>-Gennadiy<br></div></div>
