It happened again. Here is what I did:

1. on node B:
   drbdadm secondary resource
   drbdadm -- --discard-my-data connect resource

2. on node A
   drbdadm connect resource

Then everything was fine again. node A was primary, node B was secondary.

Then I shut down node B.

Then I rebooted node A.

Then, one resource on node A came up as primary without the problems. 
The second resource on node A (the one which I had to resolve from split 
brain) again did not come up:

block drbd5: State change failed: Refusing to be Primary without at 
least one UpToDate disk

The I tried to force it to primary:

# drbdadm -- --overwrite-data-of-peer primary cc-manager-templates-ha
5: State change failed: (-2) Refusing to be Primary without at least one 
UpToDate disk

Any ideas what is happening here?

Thanks
