There are ssi-specific changes to the vanilla drbd source. If you look 
at the openssi-enabled
drbd cod,  you will find that we have put in ssi-specific code.

You can always take a cvs update and apply the same ssi-specific code. 
There are only a few changes.

The ssi-specific changes can be easily identified since they are ifdef'ed
#ifdef CONFIG_CLMS or #ifndef CONFIG_CLMS
   ssi-specific code
#endif

Theres only a couple of places that have to be yet included in the ifdef 
but have the following comment

//Jai include in CONFIG_CLMS

En Chiang has the original drbd code that we started working on and he 
should be able to send out a patch. En Chiang,
could you please send out a patch to the list ?

But seeing that the problems might be specific to the Debian 
installation, I think you could also try one more thing.
If possible, see if you can get a non-root drbd partition up and 
running. This should be fairly easy and quick to try out,
if you have the disk space and SSI-installled on the nodes. All that 
needs to be done is install the drbd module and write
a drbd.conf. And then you can play around with it and make sure that 
non-root drbd mirroring is working. This should
make it much easier to debug the sync problem.
