Are you trying to export the snapshot to a server which has the parent volume already presented?

Btw, you should really run tunesys, but it seems like you also have some other issues ...

Yes. I want to export the snapshot volume to same parent volume. but ESXi Host can't see the snapshot volume. (I try re-scan path before add storage already)
