What is a staging volume in NAS auditing?
Applies to
- ONTAP 9
- Auditing
Answer
-
Staging volumes stores metadata of audit records of data access on a data volume belonging to an SVM on that aggregate.
-
The creation of staging volumes is transparent to end users. After the creation of an audit policy on any one SVM in the cluster, a staging volume is created on all the aggregates in the cluster. From then on, all other SVMs use the existing staging volumes.
-
Each staging volume consumes 2GB of free space and needs to be provisioned during configuration.
-
Staging volumes are created under a cluster SVM context, not under the data SVM context.
-
A staging volume can be accessed only by the vserver administrator. The vserver administrator can resize the staging volume in diag-mode by using the vol resize option.
Note: Consult ONTAP OS version's Release Notes and Documentation for changes or implementation details
Additional Information
- When a new aggregate is added, staging volume will be created on that aggregate by auditing subsystem if auditing is enabled.
