[DRBD-user] drbd0.7.0-59.22 mount question

[Anand Subramanian]

I am using drbd-0.7.0-59.22 (the default) with SLES 9. The linux kernel 
version is 2.6.5-7.97 which is the default kernel bundled with this 
distro.

I am using a 2-node cluster, /dev/sdb1 is the partition on both nodes, the 
partition is kept to the same size on both nodes (verified using parted) 
and ext3 is the fs-type I created on both nodes.

I could - using "drbdadm  -- --do-what-I-say primary all" make one of the 
nodes primary, the other automatically syncs up as a secondary and the 
syncing goes on fine with pleasing messages in /proc/drbd and 
/var/log/messages.

Since this is an older drbd version , it still borrows the /dev/nbd0 major 
device no. I tried to search all available documentation but this is still 
unclear to me :

1. After "insmod drbd.ko" and  "drbdadm up all" (which I do instead of 
/etc/init.d/drbd start) - shouldn't I be able to see the lower device 
mounted?

The drbd.conf details for the nodes are :

resource drbd0 {
    protocol C;
 
    on node1 {
           device /dev/nb0;
           disk /dev/sdb1;
            address 192.168.1.1:7788;
            meta-disk internal;
     }
//similar for node2

My problem is that I am not able to see /dev/nb0 mounted in /proc/mounts 
or via the mount command. If I try to mount it via : "mount /dev/nb0 
/mnt1" or something like that, it obvoiously cribs that the device is 
already in use. Since I already started drbd.
I initially had a line in /etc/fstab which specified /dev/nb0 to be 
mounted on /mnt1 with the "noauto" option, but later removed it, since I 
want to try out drbd first without heartbeat or anything else. Both cases 
produced the same problem.

Can anyone clarify this? 

Thanks,
Anand
