  Hi.

  

After setup a 2 node cluster from cluster from scratch guide using
Fedora 13 i saw that resync of data is too slow.

Cat /proc/drbd shows 240k/s

If you look at the cluster from scratch guide here:

  

http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Clusters_from_Scratch/ch07s02s03.html

  

you can see that the speed of this example is 240k too.

  

How to increase this speed?


Check /etc/drbd.conf for the  rate parameter. On a Gigabit Ethernet I
use 40M.

    syncer {

        rate 40M;

    }



See more here:

Regards,



Dan.
