Note however that the AoE protocol does not specify caching, except for optional asynchronous writes. (The aoe Linux module does not utilize asynchronous writes.) Nevertheless, the configuration suggested by the OP is unusual, and won't be very useful in my opinion. Having node B rely on a hard disk in node A leaves node A as a single point of failure. We use GFS over AoE extensively, and find it works well. However we use an AoE target that runs independent of the cluster and provides high-availability on its own. -Jeff -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
