Re: [atomic-devel] wrong storage driver when running container-storage-setup/ filesystem type doubts

I think you are not using the docker-ce version that comes with atomic. You can send the result of the command:

rpm -qa | grep -i docker

I created a thin poll storage volume using the helper script "container-storage-setup".

Here is my /etc/sysconfig/docker-storage-setup

NOTE: default driver is devicemapper in "/usr/share/container-storage-setup/container-storage-setup", exactly what I am looking for.

After running the script, here is part of docker info:
# docker info
Containers: 0
 Running: 0
 Paused: 0
 Stopped: 0
Images: 0
Server Version: 17.03.2-ce
Storage Driver: overlay2
 Backing Filesystem: xfs
As you can see, driver is set to overlay2 when I was expecting devicemapper.

NOTE: Filesystem is good, xfs, but I don't know where does this filesystem comes from as I didn't format the partition. Did the script do it?
when running lsblk, i can see this:
# lsblk -f                    
NAME                              FSTYPE      LABEL    UUID                                   MOUNTPOINT
sr0                               iso9660     config-2 2018-05-30-00-18-35-00                
├─vda1                            ext4                 8eb202fa-c75c-43f6-9a87-7ddb013ce0fa   /boot
└─vda2                            LVM2_member          Ji8MSG-yiKd-ZSlF-cop0-siUg-SPSN-xMhEkx
  └─atomicos-root                 xfs                  854965bc-06ad-40df-af9d-7bfb318c1aed   /sysroot
└─vdb1                            LVM2_member          Wblg0x-nsLd-1eyE-sZfA-jQfO-Ldvi-rUGdK1
  │ └─vg--docker-docker--pool                                                                
As  you can see, there is no shown filesystem for my docker pool . Why?

Now, looking at /etc/sysconfig/docker-storage:
# cat /etc/sysconfig/docker-storage
DOCKER_STORAGE_OPTIONS="--storage-driver devicemapper --storage-opt dm.fs=xfs --storage-opt dm.thinpooldev=/dev/mapper/vg--docker-docker--pool --storage-opt dm.use_deferred_removal=true --storage-opt dm.use_deferred_deletion=true "
Here it shows my storage driver as set to devicemapper !

So, what is exactly my storage driver, as bot command don't return the same value.

Thank you for help/explanations.
