direct links of old sources may well be a few messages off.


Hi!
Digging through my logfiles and the mail archives, I found that I might be 
running into the issue discussed in the thread started by this message:
http://www.mail-archive.com/drbd-user@lists.linbit.com/msg03275.html
I updated Novell about that and will further investigate. Any 
recommendations/fixes are highly welcome.

Mit freundlichen Grüßen / Best Regards

[DRBD-user] Strange state of DRBD-resource







Hi! 
I have a cluster with Sles11 HAE SP1 x86_64 running drbd and pacemaker. 
Replication link is two direct 1GBit links bonded with bonding mode 
balance-rr 
The system is in  a very interesting state, that will lead straight into 
desaster if a failover should occur. The master Node has the secondary as 
unknown with blocks out of sync, while the secondary thinks everything is 
OK. if a failover occurs, it happily comes up with stale data. I have no 
idea what could cause this. 
 Novell support is already involved, but they have not yet come back with 
a solution since last wednesday. Any Ideas
