I tried to delete all files except aci-manifest.yml and to run sudo dgr clean build but it doesn't help.

What do I wrong?

dgr requires rkt storage to be on an overlay compatible fs. While rkt can work without it, dgr is using it to identify what is installed in the current aci and not comming from dependencies.

this link can help : https://coreos.com/rkt/docs/latest/subcommands/prepare.html.

Thanks for the clarification. It's unobvious.

dgr is checking that overlayfs is available but do not check if rkt is on a compatible fs. looking at your log, we can improve the error message : #260

After I formatted /var/lib/rkt partition with mkfs.xfs -n ftype=1 the problem has gone.
