You can configure a volume for thin provisioning, thick provisioning, or semi-thick provisioning, depending on your space requirements.

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 snapshots is enabled.

Step

  1. 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 AFF systems and for non-AFF DP volumes. Otherwise, it defaults to volume. For existing FlexVol volumes, use the volume modify command to configure provisioning options.

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

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

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

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

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

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