inline data compaction and existing data

ACHOU_SIMG

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,

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

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