Unchecking "Only datas with affinity" on a storage pool. Destructive or not ?

Hi all,

I have an Xsan 2.

On this Xsan only one volume.

In this volume several storage pools.

Some of those storage pool are configured to accept "user datas only" with checkbox "only datas with affinity" checked.

I would like to uncheck the "Only datas with affinity" checkbox on one of the storage pools (because it's not used and the storage pools without affinity are more or less full).

But before doing this I would like to be sure it wil not be destructive for the Xsan volume.

Anyone tryed this ? Does unchecking this checkbox in XSan Admin for one storage pool will destroy the full volume ?

Thanks for your help.
