What does an lsmod show? Is drbd loaded? What version of the kernel are you
running? What library is your kernel module in.

Subject: [DRBD-user] DRBD configuration
Hi Ellenberg,
I will be very thankful if you please help me to resolve my query.
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.
Please find the configuration details below.

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 ...
Thanks & Regards
