inline data compaction and existing data

Hi,

 

ONTAP 9.1RC1

 

I plan to enable inline data compaction but the volume already has large amuont of data. Does data compaction act on the existing data?

 

Thanks,

It is inline process, activated whilst data is being written to the storage system, so will have no effect on already stored data:

Okay, turns out, with ONTAP 9.1 this command (in advanced privilege) will compact existing data:

cluster::*> volume efficiency start -vserver <svm> -volume <volume> -scan-old-data true -compaction true
