<P><FONT SIZE=2>Hi Ellenberg,<BR>
<BR>
I will be very thankful if you please help me to resolve my query.<BR>
<BR>
I have installed & configured drbd-0.7.16 on two systems. When trying to start the drbd by issuing command "/etc/init.d/drbd start" I am getting this "Starting DRBD resources: Can not load the drbd module." I have created the device node by command "for i in `seq 0 15` ; do mknod -m 0660 /dev/drbd$i b 147 $i; done". My only suspect why its not working is, if we can any way create device node perfectly then I hope we can resolve the problem.<BR>
<BR>
Please find the configuration details below.<BR>

I have used command "for i in `seq 0 15` ; do mknod -m 0660 /dev/drbd$i b 147 $i; done" to create device node. but when I use "ls" it shows but when I use command "df -ah" or "lsmod" it is not showing. I need your help ...<BR>
<BR>
