Abstract
Updates for clients accessing a data volume across fault tolerance zones may be replicated. Requests to write or read a block of a logical volume with replicas located in different fault tolerance zones may be sent to the different replicas. Responses for the different requests may be evaluated to determine whether quorum is satisfied for the write or read of the block of the logical volume. For writes that satisfy quorum, a request to commit the write may be sent to the replicas of the logical volume.
