Do space utilization considerations for ONTAP upgrade apply to root aggregates?
Applies to
- ONTAP 9
- ONTAP Upgrade
- Root Aggregate space utilization
Answer
No, the space consideration apply to deduplicated volumes/aggregates only. The root volume and aggregate should not contain any user data and do not have deduplication enabled.
The root aggregate is created with 95% utilization by design, as it contains the root volume (vol0), that has space guarantees enabled (thick provisioned).
Root aggregate with 95-99% utilization should not prevent a successful upgrade nor cause the deduplication to be disabled.
