Thanks for the info. I didn't notice that these *-storage-setup scripts were installed as part of the prerequisites playbook in the ansible repo. So yes, they are available before starting the deployment process.
In the interim I had just deployed LVM manually and mounted a big volume onto /var/lib/containers. Is there anything that details exactly what these scripts are doing and why? Such as if using overlay2, why would one want to use these scripts instead of a self-managed LVM mounted on /var/lib/containers? LVM is easy, and I would think doing it manually provides more flexibility than a script trying to guess what you want to do, and is also easier to understand. Is this just meant to automate the LVM tasks for people who are unfamiliar with it? -Patrick On 2018/3/21 02:03, Frederic Giloux wrote: > Hi Patrick > > on RHEL 7.4 (and probably CENTOS 7.4) look at "man > container-storage-setup".
