Hi,

 

I would like to know about ScaleIO failure impact in detail, hoping this is the right place to make a question like this.

When we use volumes, as far as I know, each of volumes is split into lots of chunks and they are placed in SDSs like the below figure.

In this case, two or more SDS's down(different fault sets) can impact on parts of all the volumes used by mutiple VMs as both mirrors are broken.

Here are a few questions for this:
- Does this case make faults of VMs using the volumes?
   - If so, what we can do to restore the VM?
   - If not, what impacts are expected?

- Will it be fine before the system access the data?

 

BR,
