[DRBD-user] DRBD setup issues on 2 Fedora systems

Hey all,

I'm very new to DRBD and I'm having some setup issues with it on 2 systems. Both are running Fedora Core 1 and are running hardware RAID 5 arrays.

Install appears to have gone ok on both systems, however I have noticed that the install script creates the module under /lib/modules/2.4.22-1.2174.nptlcustom instead of the 2.4.22-1.2174.nptl folder. I'm not sure how to change that either. As this is RedHat, making your own custom kernel will always name it differently I think. But, there were no errors during the install, but I can't help but think that this is the cause of my problems, as can be seen below.

Once it's installed, I set up my drbd.conf files on both machines to look like this:

resource drbd0 {
          protocol=C
          fsckcmd=fsck.ext3 -p -y

          on Fileserver1 {
            device=/dev/nb0
            disk=/dev/sda2
            address=192.168.8.250
            port=7788
          }

          on Fileserver2 {
            device=/dev/nb0
            disk=/dev/sda2
            address=192.168.8.249
            port=7788
          }
        }

After that's set up, I try to start the service:

/etc/init.d/drbd start
drbd: pre-parsed needs update, parsing /etc/drbd.conf
............................................................
............................................................
............................................................
drbd: ERROR: modprobe -s drbd minor_count=1 [255]:
drbd: ERROR: NO OUTPUT

Can not load the drbd module.

I'm pretty much stuck here. Both machines do this. I can't even get drbdsetup to run right, but I don't know if it's related to this or not. When I try, I get this:

drbdsetup /dev/nb0 disk /dev/sda2
can not open device: No such device or address

Both devices show up in my /dev folder, and I've even tried /dev/MAKEDEV to make sure, but I still get this error. 

In short, I'm not having much luck getting this working. Any advice would be greatly appreciated.

Thanks,
Brandon
