Hi all,
          Bandwidth is an important issue in DRBD during replication of
data. If bandwidth is properly utilized then replication will be faster
and speed is what everyone needs.
        When bandwidth utilization comes into picture, compressing data
is what
is needed. Earlier discussions were going on to use vtun with a tcp
tunnel with zlib compression factor 9 or so to achieve compression.
        What about implementing compression in DRBD itself. Like using
zlib to
compress each packet and decompress it on receiver side in DRBD code
itself rather than using vtun and all. Wont it solve the purpose? 

Thanks and Regards,
Komal Nawandar.
