[DRBD-user] unable to format /dev/drbd1

[Frank Torontour]

   Hi,

Here is my config file:  (I tried to make it as simple as possible)

global {
  usage-count yes;
}
common {
  protocol C;
}
resource r0 {
  on mach1 {
    device    /dev/drbd1;
    disk      /dev/hdb1;
    address   66.159.32.31:7789;
    meta-disk /dev/hda3 [1];
  }
  on extra1 {
    device    /dev/drbd1;
    disk      /dev/hdb1;
    address   66.159.32.11:7789;
    meta-disk /dev/hdb2 [1];
  }
}


NOTE: I know you cannot mount the device on the secondary and I am working
on the primary.

    I have followed the instructions on the http://www.drbd.org web site
for installing drbd. I have downloaded the source and compiled it
successfully. I have run into 2 problems.  I cannot do

drbdadm attach r0

if I have /dev/hdb1 on mach1 mounted.  How do i work with a drive that
has data already on it?  The instructions say to drbdadm attach r0
but it does not work if the partition is mounted.

So I did not mount the partions and went through the rest of the instuctions.
All seems to be ok and I have this from /proc/drbd

root at mach1:/etc# cat /proc/drbd
version: 8.3.1 (api:88/proto:86-89)

If I try and format /dev/drbd1

root at mach1:/etc# mke2fs /dev/drbd1
mke2fs 1.35 (28-Feb-2004)
Could not stat /dev/drbd1 --- No such file or directory
The device apparently does not exist; did you specify it correctly?

Could you tell me what is wrong?
