Re: [atomic-devel] Question about Docker Storage

You're right.  I didn't realize there was 2 LVs.  So now I give half to root and half to docker:

lvextend -l +50%FREE /dev/atomicos/root
lvextend -l +100%FREE docker-pool

Is this an Atomic Host system? Is it CentOS?

Is there another LV that is the container storage? I'm thinking you should be able
to resize the LV.
