I have some virtual volumes with the same simple structure(virtual volume->device->extent->storage volume, i.e. 1:1 mapping), why the properties of some volumes are extendble with storage-volume method, but others are not-supported ?
You cannot expand a 1:1 virtual volume if you claimed the underlying storage volume with application consistency flag. You can disable that flag from CLI. Please take a look at the following KB324150
Thanks, you are correct.
