I have a similar problem too. But unlike the case with VMs I just copied and erased file data to the deduplicated disk several times. Now the logical disk is empty, and there hasn't been any activity on it for a week. But 20 GB of raw storage files *.spspx are still there. Deduplication, deletion su...
Do you have plans to implement disk extend functionality in future versions?
As for shrink, I guess It could be done by creating a brand new thin-provisioned disk followed by copying the contents of the old disk to the new one. Anyway it will require some extra disk space for that.
Is there any way to extend (increase the reported to OS disk size) or shrink (decrease the size of the underlying .spdata files) of the deduplicated thin-provisioned disk in SW 5.7.1733?
Is that posssible to change the target properties (i.e. caching policy or image file location) after it is created? The only options I see are to delete and force delete the target. The target is deduplicated disk.
