How to create fploicy to limite only txt file?

[AllenChang]

I create a fpolicy to limited a volume can be store .txt file

I use this command

First I create a event

filer>vserver fpolicy policy event create -vserver fpsvm1 -event-name event1 -file-operations create,write,rename -protocol cifs

Than I create a policy

filer>vserver fpolicy policy create -vserver fpsvm1 -policy-name policy1 -events event1 -engine native -is-mandatory true -allow-privileged-access no -is-passthrough-read-enabled false

And I create a scope

filer>vserver fpolicy policy scope create -vserver fpsvm1 -policy-name policy1 -file-extensions-to-exclude txt -volumes-to-include vol1

finially I enable the policy

filer>vserver fpolicy enable -vserver fpsvm1 -policy-name policy1 -sequence-number 1

but I found the volume still can store any file

How must I modify configuration?

Hello, 

While creating the scope, we had used the option -file-extensions-to-exclude.
This parameter specifies list of file extensions for which FPolicy processing will be excluded.

Please modify the  scope and use option -file-extensions-to-include txt in place of  -file-extensions-to-exclude to make Fpolicy process this file extension. 

Here is the matching KB for your reference: https://kb.netapp.com/on-prem/ontap/da/NAS/NAS-KBs/How_to_configure_native_Fpolicy_in_ONTAP_to_block_extensions 

Please do let me know if it fixed the issue for you.

Cheers!
