ONTAP Logging for Compaction operations

STEVEWILLSQ — Wed, 04 Jun 2025 10:08:54 GMT

Hi all,

I have a customer that is switching their flexgroup members from thin provisioned back to thick. In order to do this they need to undo compaction and any cross volume dedupe for it to work as per - https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Systems/FAS_Systems/The_volume's_space_guarantee_cannot_be_changed_to_%22volume%22

The compaction undo is taking a long time, which is fine but is there a way to track it's progress? The SIS logs don't show anything at all. Is there somewhere else we should be looking. (SIS logs are also no longer in Autosupport). Customer is running ONTAP 9.9.1

does "volume efficiency show -instance" gives any data?

Maybe wafl scan status? https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/What_is_the_%22wafl_scan_status%22_command%3F
