RHCSA Objective: Manage layered storage

As I end my preparations for RHCSA, I'm going back over the objectives list to find weaknesses that need touching up.

I'm familiar with using LVM as a layer of abstraction above "physical" block devices, but there's another objective that touches LVM.  Does anyone know if "Managed layerd storage" is referring to being able to configure / manage Stratis?

Re: RHCSA Objective: Manage layered storage

Hi,

Yes, "Manage layered storage" is about Stratis.

The rule is if its in the objectives, you are supposed to know it.

That does not means it will be asked in your exam though...

It's not a too complicated topic and the commands are fairly easy to use, good luck!

Re: RHCSA Objective: Manage layered storage

Thanks.  I'll work with it in my lab soon.  I'm not sure about its usefulness since we have LVM and VDO, but yes, since it's an objective, I'll become familiar.
