[DRBD-user] Local (async) Mirror

[Senne Vaeyens]

Hi,

I’m using 8.4.4 on CentOS 6.5
I try to configure an NFS server as explained by Craig Carl in the following presentation: http://www.slideshare.net/AmazonWebServices/nfs-and-cifs-options-for-aws-stg401-aws-reinvent-2013 , (youtube video of the presentation can be found here: https://www.youtube.com/watch?v=xbuiIwEOCAs) 

Craig explains on slide 12 how you configure a local mirror with brbd;

It goes somewhat like this...

resource r0 { 
	on az-a{ 
		device /dev/drbd0; 
		disk /dev/md0; 
		address 10.1.1.1:7789; 
		meta-disk internal; 
	} 
	on az-a{ 
		device /dev/drbd1; 
		disk /dev/md1; 
		address 10.1.1.1:7789; 
		meta-disk internal; 
	} 
} 

I’ve already read the following (quite old) thread: http://www.gossamer-threads.com/lists/drbd/users/20817 
This tread suggest that a config like Craig suggest would never work, my tests indeed confirm that this setup doesn’t work,; I get errors like:

drbd.d/r0.res:8: conflicting use of host section 'r0: on xxxxxx' ...
drbd.d/r0.res:2: host section 'r0: on xxxxxx' first used here.

Is there any way to get this local async replication working?

Thanks
