[DRBD-user] Syncing new disk w/ existing node

Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

I'm sure there is something obvious I am neglecting, but I can't figure 
this out:

[root at rhdmz01 ~]# rpm -qa |grep drbd

I have a box running DRBD without a second node - I just brought the 
second box online this morning. I'm able to connect them, run them 
pri/pri, however I'm unable to attach the disk of the new node.

[root at rhdmz01 ~]# drbdadm attach home_ftp
Failure: (119) No valid meta-data signature found.

        ==> Use 'drbdadm create-md res' to initialize meta-data area. <==

Command 'drbdsetup /dev/drbd1 disk /dev/VolGroup00/home_ftp 
/dev/VolGroup00/home_ftp internal --set-defaults --create-device' 
terminated with exit code 10

I didn't think I had to do that, but I tried it anyway... Now when I do 
an attach I get this in the logs:

drbd2: disk( Diskless -> Attaching )
drbd2: No usable activity log found.
drbd2: max_segment_size ( = BIO size ) = 32768

drbd2: before-resync-target handler returned 3, dropping connection.
drbd2: peer( Primary -> Unknown ) conn( WFSyncUUID -> Disconnecting )

Any ideas what I'm missing here?
