volume efficiency inactive-data-compression start
Start inactive data compression on a volume.
Availability: This command is available to cluster and Vserver administrators at the advanced privilege level.
Description
The volume efficiency inactive-data-compression start
command is used to start inactive data compression on a volume.
Parameters
-vserver <vserver name>
- Vserver Name (privilege: advanced)-
This specifies the vserver of the volume.
-volume <volume name>
- Volume Name (privilege: advanced)-
This specifies the volume on which inactive data compression should be started.
[-s, -inactive-days <integer>]
- Compression Days Count (privilege: advanced)-
Data older than 'inactive-days' days is compressed.
[-m, -scan-mode {default|compute_compression_savings|extended_recompression}]
- scanner mode (privilege: advanced)-
This specifies in which mode inactive-data-compression-scanner should be started. Three modes are available: 'default', 'compute_compression_savings' and 'extended_recompression'. 'default' scanner will start compressing the cold data in volume. 'compute_compression_savings' scanner will calculate the auto adaptive compression savings on the volume. 'extended_recompression' scanner will attempt to re-write existing cold data to reduce internal fragmentation.
Examples
The following example displays information for starting inactive data compression scan on volume "vol1":
cluster:::> volume efficiency inactive-data-compression start -vserver vs1 -volume vol1 Inactive data compression scan started on volume vol1 in Vserver vs1.
