<br><font size=2 face="sans-serif">Hi All,</font>
<br>
<br>
<br><font size=2 face="sans-serif">We had a few discussion about this issu.</font>
<br>
<br><font size=2 face="sans-serif">With all the exchange on the subject.</font>
<br><font size=2 face="sans-serif">I think I can say I understand how drbd
work on a high latency network.</font>
<br>
<br><font size=2 face="sans-serif">Just to make sure I really understand.</font>
<br>
<br><font size=2 face="sans-serif">So since I'm working with a high latency
network</font>
<br><font size=2 face="sans-serif">I have decided to use protocol A</font>
<br>
<br><font size=2 face="sans-serif">Now this protocol work with 2 must.</font>
<br><font size=2 face="sans-serif">1) the data have to be written on the
primary machine disk</font>
<br><font size=2 face="sans-serif">2) the data must be write in the tcp/ip
buffer.</font>
<br>
<br><font size=2 face="sans-serif">So the problem I get is when I copy
large file (350MB and more) on the primary</font>
<br><font size=2 face="sans-serif">machine the drbd partition seems to
stop accepting writing on his primary partition</font>
<br><font size=2 face="sans-serif">until the network start emptying the
tcp/ip buffer. Cause with this large file copy</font>
<br><font size=2 face="sans-serif">over the 10mb line just seems to be
to slow to avoid drbd to stop momentaraly </font>
<br><font size=2 face="sans-serif">the writing on the primary partition.</font>
<br>
<br><font size=2 face="sans-serif">So with this said my question is :</font>
<br>
<br><font size=2 face="sans-serif">I went on to the drbd web page from
linbit to read about DRBD+</font>
<br>
<br><font size=2 face="sans-serif">I was wondering if I would work with
this version(intead of the free version) if I would get some improvment.</font>
<br><font size=2 face="sans-serif">I see on the webpage a few of the features
that are optimize to get better performance.</font>
<br>
<br><font size=2 face="sans-serif">So if I would go with the not free version
of drbd (DRBD+) could I expect to improve my situation or</font>
<br><font size=2 face="sans-serif">it's not worth</font>
<br>
<br><font size=2 face="sans-serif">Thanks !</font>
