POST /storage/flexcache/flexcaches

Creates a FlexCache in the cluster.

Required properties

  • name - Name of FlexCache volume.

  • origins.volume.name or origins.volume.uuid - Name or UUID of origin volume.

  • origins.svm.name - Name of origin Vserver.

  • svm.name or svm.uuid - Name or UUID of Vserver where FlexCache will be created.

  • path - Path to mount the FlexCache volume

Default property values

If not specified in POST, the following default property values are assigned:

  • size - 10% of origin volume size or 1GB per constituent, whichever is greater.

  • constituents_per_aggregate - 4 if aggregates.name or aggregates.uuid is used.

  • volume flexcache create
