Snapshot acquired by FAS system is not recognized by Manila

Hi ,Now I use Manila and have some questions.

 

Please answer the following questions.

 

Question1.
After creating snapshot on Netapp side, nothing was displayed even if "manila snapshot-list" command was executed on manila side.
Why is the snapshot created on Netapp not recognized on manila? Is it a specification?

Is it possible to manipulate snapshots acquired on Netapp from the manila command?

 

Question2.
Is there any problem in the operation on the Manila side even if the snapshot acquired on the Netapp side is manually restored?

In addition, when it was manually restored snapshot acquired on the Manila from Netapp how Manila recognize ?

What is the proper restore method when using Manila?

 

Regards,

The simplest way to do this will be to create Snapshots from Manila itself. You can add the "snapshot_support" extra spec to your Manila share type and have the NetApp Manila driver create snapshots on the FAS cluster through OpenStack. The Manila snapshot maps to an ONTAP Snapshot on the backend [1]

If snapshots are created through Manila, OpenStack supports reverting a share to its most recent snapshot. This would also require adding the "revert_to_snapshot_support" extra spec to your Manila share type. In addition, you can also create shares from snapshots.

Hi balaramesh,

 

Thanks for the reply.

 

After confirming the response you adviced,

is my understanding correct that Openstack does not support restoring using snapshots acquired on FAS?
