Sorry if these are hard to read.. they are even harder for me, as i am
forced to abandon the project.

This version connected much more regularly than 0.5.6, but still not
consistant.

If you need more information, i may or may not be able to use these machines
for this purpose after today.

What type (manufacture/model) of NICs are you using ?

Ever tried to run the benchmarking (benchmark/run.sh) script ?

Your connection is always interrupted by a timeout...
... you can try to increase the timeout value by adding "-t 100" to
tthe drbdsetup call.

Aren't there some NICs/drivers which can not send if they are idle for some
time ?

1. frontal is getting the parameter packet from temporal
Log messages: agreed size...
2. You are switching frontal into primary state, therefore it tries
to send a C-State packet, the networking-subsystem is not able to send
this packet within 3 seconds.
Log messages: send times out!!
3. Frontal is closing the connection.

At home I am useing cheap NE2000s. I know it's working with RTL8139 and
via-rhine.

TO ALL SUBSCRIBERS:
Can you post the type/driver of your network cards, and a note if it's
working? Thanks in advance.

I use drbd on on two systems one with 2 RTL8139 card
and one with two identical "cheap" (18 pounds) card (tulip driver)
Both systems are working fine.

To set them up I configure them to use a very high "transfert rate value".
DRBD is them unable to communicate and then flood the screen with the
optimal value (or at least, I think it is.. philipp ???).
I don't know if it is the best way to do but it work fine for me.

With the same hardware and only the network card changing
I had a difference of 20% between the two configuration value
(in favor of the realtech)

Ok, here goes, boss didnt deploy the servers, so i had another day to play
with them,
the machines are equipped like this:
each, identical, built-in Intel Etherexpress Pro 100, and a Intel
Etherexpress Pro 100 as a seperate card
ive tried with similar results on both cards.

Even if it is timing out, by my estimation, drbd should NEVER go back to
unconfigured, but it does, and very often.

Not going to post my whole situation, just the beginning, this is after a
clean boot, both machines
commands are numbered this time

In order to create a better datadisk script and specialy the init part.
It would be nice to get a /proc more "verbose" or "readable".

I my case a had to write a small server (in shell with tcpserver) binded to
the private interface running the input it receive. A don't want rsh
installed and ssh is bringing some side problems.

This allow me to determine the state of the other computer ping to check
it's presence and datadisk state remotely to know it's state to setup the
state the node at boot time.

I think most of this could be done more cleanly with drbd, if all is already
here to do it I would be please to fix my own code.
All comment (even flame :) are welcome.

Thomas, please tell us more. Which information do you want to see in
/proc/drbd. Maybe you can give us an example "screenshot" of the
/proc/drbd you are thinking of ?
