instant snapshot (vxsnap) - multiple volumes - are the snapshots consistent between each other ?
Using tradition 3rd mirror break off snapshot using vxassist, when multiple volumes are specified on the snapshot command, all the volumes are split atomically and all the volumes are split exactly at same point in time. This is a very very useful feature. vxassist man page clearly document this behavior (quoted below) "The snapshot command accepts more than one volume. All the given volumes are split atomically (in a single transaction). That is, all the given volumes are relatively consistent as a result of taking the snapshot" However when it comes to Instant snapshot (space optimized on full size instant snapshot), the man page for vxsnap does not describe this behavior when multiple volumes are snapped in one command. 1) Is the behavior of atomic split still same as legacy third mirror breakoff? 2) Are the volumes relatively consistent between each other?Solved1.9KViews0likes6Comments
