I've recently added an AFF HA-Pair to our cluster (we now have 4 nodes, two FAS8060s and two AFF8080s). Documentation indicates that the default is for volumes to be thin provisioned and inline compression/deduplication. I've just moved my first two volumes to the AFF, and neither were thin provisioned or configured with inline deduplication/compression. Any suggestions here? Am I missing a detail?
Also: I also don't show that these options are checked when I create a new volume in System Manager on one of the AFF aggregates. AFTER creation, inline compression and deduplicatoin are enabled, but not thin provisioning.
Lastly: does anyone know if the limitations of eight deduplication jobs at a time apply on AFF systems? I assume that only would apply if scheduled deduplication was added to the default inline deduplication.
I am on OnTAP 8.3.2. Thanks in advance!

Please refer Compression behavior after volume move from 8.3.1+ FAS node to 8.3.1+ AFF node. Table 10 on page 46 of the link http://www.netapp.com/us/media/tr-4476.pdf
Page 51 :
Between AFF and FAS nodes: - Both AFF nodes and FAS nodes running a Data ONTAP 8.3.1 or later release:
o No change after the move: all volume configurations and savings are retained.
o All Data ONTAP 8.3.1 and later FAS compression features are supported on the volume.
Creating a mirror relationship from a destination SVM, the default value for created volume in AFF is thin.
If created from source SVM then it does not set the destination volume settings to thin by default.
