[Gluster-devel] GlusterFS 1.3.0-pre2.3: AFR not working

[Gerry Reno]

Yes, I think it is DRBD 0.8 that has this where you can mount both sides 
simultaneously. We are only using DRBD 0.7 right now and I'm looking to 
see if GlusterFS may be a more capable solution for us. Looking for 
better scalability. I've never had to work with the underlying devices 
in DRBD. Worse case I just forced a full sync. And I'm hoping that is 
the case with GlusterFS.
