Configuring volume provisioning options

You can configure a volume for thin provisioning, thick provisioning, or semi-thick provisioning.

About this task

Setting the -space-slo option to thick ensures the following:

  • The entire volume is preallocated in the aggregate. You cannot use the volume create or volume modify command to configure the volume's -space-guarantee option.

  • 100% of the space required for overwrites is reserved. You cannot use the volume modify command to configure the volume's -fractional-reserve option.

Setting the -space-slo option to semi-thick ensures the following:

  • The entire volume is preallocated in the aggregate. You cannot use the volume create or volume modify command to configure the volume's -space-guarantee option.

  • No space is reserved for overwrites. You can use the volume modify command to configure the volume's -fractional-reserve option.

  • Automatic deletion of Snapshot copies is enabled.

Configure volume provisioning options:volume create -vserver vserver_name -volume volume_name -aggregate aggregate_name -space-slo none|thick|semi-thick -space-guarantee none|volume

The -space-guarantee option defaults to none for AFA systems and for non-AFA DP volumes. Otherwise, it defaults to volume . For existing FlexVol volumes, use the volume modify command to configure provisioning options.

Example

The following command configures vol1 on SVM vs1 for thin provisioning:

cluster1::> volume create –vserver vs1 -volume vol1 -space-guarantee none
Example

The following command configures vol1 on SVM vs1 for thick provisioning:

cluster1::> volume create –vserver vs1 -volume vol1 -space-slo thick
Example

The following command configures vol1 on SVM vs1 for semi-thick provisioning:

cluster1::> volume create –vserver vs1 -volume vol1 -space-slo semi-thick
