Hello Forum,
I'm currently strugeling with a DRBD related problem. We have a two node cluster running. These to nodes share their data via DRBD.
Last week we had a power failure in our datacenter. One of the nodes crashed and rebooted. From this point on cat /proc/drbd shows the following output:
NODE1:
----------------------------------------------------------
version: 8.3.0 (api:88/proto:86-89)
GIT-hash: 9ba8b93e24d842f0dd3fb1f9b90e8348ddb95829 build by root at xen0, 2009-06-04 09:17:59

On node 2 are running severell virtuall maschines hosted by XEN.
The data on node 2 is up to date and I want to keep this data.
Now I try to sync all data from node2 to node1.
I followed the "Manuall split brain recovery" from drbd.org and did the following:
On Node1:
drbdadm secondary all
drbdadm -- --descard-my-data connect all
Now node1 was waiting for connection
On Node2:
drbdadm connect all
Nothin happened now. But node1 went from waiting for connection to Standalone.
Am I missing something? I thought that the cluster would connect now and all data would be synced from node2 to node1.
What am I doing wrong here?
With kind regards
Kai Zemke
