You can run efficiency operations manually on a volume by using the volume efficiency start
command.
Depending on the efficiency operation you want to run manually, you must have enabled deduplication or both data compression and deduplication on a volume.
When temperature-sensitive storage efficiency is enabled on a volume, deduplication is run initially followed by data compression.
Deduplication is a background process that consumes system resources while it is running. If the data does not change often in a volume, it is best to run deduplication less frequently. Multiple concurrent deduplication operations running on a storage system lead to a higher consumption of system resources.
You can run a maximum of eight concurrent deduplication or data compression operations per node. If any more efficiency operations are scheduled, the operations are queued.
Beginning with ONTAP 9.13.1, if temperature-sensitive storage efficiency is enabled on a volume, you can run volume efficiency on existing data to take advantage of sequential packing to further improve storage efficiency.
Run efficiency manually
-
Start the efficiency operation on a volume:
volume efficiency start
ExampleThe following command allows you to manually start only deduplication or deduplication followed by logical compression and container compression on the volume VolA
volume efficiency start -vserver vs1 -volume VolA
Repack existing data
To take advantage of sequential data packing introduced in ONTAP 9.13.1 on volumes with temperature-sensitive storage efficiency enabled, you can repack existing data. You must be in advanced privilege mode to use this command.
-
Set the privilege level:
set -privilege advanced
-
Repack existing data:
volume efficiency inactive-data-compression start -vserver vserver_name -volume volume_name -scan-mode extended_recompression
Examplevolume efficiency inactive-data-compression start -vserver vs1 -volume vol1 -scan-mode extended_recompression
