Hello barbarsalem,

 I think you mixed up cnode1 and 2 in the last paragraph.

If you created the docs on cnode2 they must be replicated to cnode1, right?

 Sincerely,

i successful installed DRBD.

i tried to edit the /etc/drbd.conf, but i have no idea what is 'device /dev/drbd0'  ........can you or anyone explain..?

refer to quoted below, what is  'device node to use: /dev/drbd0'.

"The device node to use: /dev/drbd0 - DRBD block device." 

one more... i did not implement this:
'insmod /lib/modules/2.6.9-55.0.9.EL/extra/drbd.ko'

Thanks
