Hi Sahana,
Thanks. We did have auditing configured (but not enabled) for one SVM prior to the two new aggregates being created. All aggregates in the cluster (with the exception of the aggr0s containing the root vols) have 36% free space or greater.
Both the new aggrs still have nearly 100% free space, as we have not created or moved any volumes to them yet. According to the bug detail, creating large aggregates can shut down the auditing function, but we already had it disabled prior to creating the aggregates. However, I see that both new aggrs now contain MDV_aud vols, so I'm not sure if that indicates an actual issue or not. Also, I noticed the bug detail shows the bug being fixed as of ONTAP 8.2.2.RC1 (we're running 9.1 GA).
Thank you for your insight! I'm sure the issue lies with the auditing function, so I'll continue to investigate this angle.
