Cluster Configured RF3 with 5 Node.

2 node Failed and 3rd node also ready to failure stage.

Now will try to change RF3 to RF2  -- 

In this case scenario it will work RF2 configuration and recover the data?

Hey 

This sounds like a scary situation..

That third node failing will make for a harder time generally because iirc even changing all containers from RF3 to RF2 will still mean the cluster services are RF3 anyway and last time I checked you couldn't change that config without a rebuild.

Are you planning on replacing the failed nodes, maybe you could use the parts from the two failed to make one working to bring back in to protect against the impact of the third failure.

I don't know if the system will let you make these changes to the RF on the fly whilst in a failure state but it'd be good to know…

I suspect there's too many moving parts here it'd be wise to open a case with support and look at the specifics.

Hello @Shield07 

As Kcmount said you can revert storage container to RF2 but cluster configuration will remain RF3, the only way to completely revert to RF2 is re-image the cluster.
