Hi. It’s mentioned in documentation that this module doesn’t modify existing FlexCache volumes with two exceptions. What are the exceptions?

When using REST, a prepopulate can be started on an exising FlexCache volume.

When using REST, the volume can be mounted or unmounted. Set path to ‘’ to unmount it.

And what about size change? It will recreate FlexCache?

dark cypress Mar 31, 2023, 8:09 AM

#

we cannot modify size.

#

from REST api - https://library.netapp.com/ecmdocs/ECMLP2884821/html/index.html#/storage/flexcache_modify

only supported in create, we cannot modify it.
size integer
readCreate: 1
Physical size of the FlexCache. The recommended size for a FlexCache is 10% of the origin volume. The minimum FlexCache constituent size is 1GB.

Now it’s clear.
But it so overcomplicates simple task of changing size for FlexCache ☹️

#

is it possible to modify size in cli?

#

if it can be modified in cli we can use na_ontap_rest_cli module but I think we cant - https://docs.netapp.com/us-en/ontap-cli-98/volume-flexcache-origin-config-modify.html#examples
