[Gluster-users] Is replica data usable by clients?

Hi Elias, 

Online replica's will be used to satisfy client requests. You'll typically see a delay when accessing files, while the cluster determines that the node/brick is dead, and then access resumes using the remaining brick(s). 

gluster tracks updates against the online replica, such that when the other brick returns self heal can get to work and catch up with the changes on the other brick. 

Does that make sense?
