GET /storage/flexcache/origins/{uuid}

Introduced In: 9.6

Retrieves attributes of the origin of a FlexCache in the cluster.

Expensive properties

There is an added computational cost to retrieving values for these properties. They are included by default in GET results. The recommended method to use this API is to filter and retrieve only the required fields. See Requesting specific fields to learn more.

  • flexcaches.ip_address - IP address of FlexCache.

  • flexcaches.size - Physical size of FlexCache.

  • flexcaches.guarantee.type - Space guarantee style of FlexCache.

  • flexcaches.state - State of FlexCache.

  • flexcaches.dr_cache - True if the cache is a DR cache.

  • volume flexcache origin show-caches

Parameters

Name Type In Required Description

array[string]

False

Response

Status: 200, Ok
Name Type Description

_links

_links

block_level_invalidation

boolean

Block level invalidation enables the FlexCache volume to retain blocks that are not changed at the FlexCache volume without having to evict them. This means that the FlexCache volume does not have to again incur the computational cost of fetching blocks over the WAN from the FlexCache volume origin on the next client access. Block level invalidation is a property of the origin volume. Without block level invalidation, any write at the origin volume would evict the whole file at the FlexCache volume, since by default, origin volume does a file level invalidation.

flexcaches

array[flexcache_relationship]

global_file_locking_enabled

boolean

Specifies whether a global file locking option is enabled for an origin volume of a FlexCache volume.

name

string

Origin volume name

svm

svm

Origin volume SVM

uuid

string

Origin volume UUID. Unique identifier for origin of FlexCache.
