The following exceptions apply to one or more inline storage efficiency features:
-
Only read-write volumes can support default inline storage efficiency enablement.
-
Volumes with compression savings are omitted from enabling inline compression.
-
Volumes that have postprocess deduplication turned on are omitted from enabling inline compression.
-
On volumes where volume efficiency is turned off, the system overrides the existing volume efficiency policy settings and sets it to enable the inline-only policy.
