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

Thanks,

Chad

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.
