Parameters for a new file system
Set the parameters that are listed in the following table after a file system is created.
| Parameter | Description |
|---|---|
| afmObjectXattr | Specifies user-extended attributes to be synchronized with a cloud object storage. If this option is skipped, the AFM to cloud object storage does not synchronize user-extended attributes with the cloud object storage. |
| afmObjectDirectoryObj |
AFM to cloud object storage supports directory objects. All directories with and without objects can now be synchronized to the cloud object storage. You can now set extended attributes on directories with the directory object support. |
|
afmObjectACL |
Enables the cache to synchronize ACL to the cloud object storage server. If not specified, AFM will not synchronize ACLs to cloud object storage. Default is disabled ACL synchronization. |
|
afmObjectFastReaddir |
Improves the read-dir performance of an AFM to cloud object storage fileset by skipping synchronization of extended attributes and ACLs of an object between a cloud object storage server and a cache fileset. When this option is set, deleted objects on the cloud object storage server will not be reflected immediately on the cache fileset. This option shall not be used with the afmObjectXattr option. |
|
afmObjectSSL |
Specifies SSL certificate verification. This option is valid only with HTTPS. Default value of this parameter is disabled. |
|
afmObjectGCS |
This parameter is used for Google cloud object storage backend. Enabling this parameter makes AFM to cloud object storage compatible with the list operations used by the Google cloud object. |
