Re: Adding host storage during advanced installation

2018-03-21 Thread Judd Maltin 
WRT docker, it's part of the startup check/setup process, ensuring that you
have storage for your containers locallly.
/etc/sysconfig/docker-storage-setup has several settings that makes it easy
to manage the (optional creation) and use of LVM by docker.

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?

Re: Adding host storage during advanced installation

2018-03-21 Thread Frederic Giloux 
Hi Patrick

on RHEL 7.4 (and probably CENTOS 7.4) look at "man
container-storage-setup". Similar to docker-storage-setup it is a helper
script to configure the storage used by CRI-O.
In regard of the procedure I will second what Louis said:
- first prepare your nodes, including storage
- install and run your cluster
If you need later on to extend your storage capacity you can re-run the
script to add block devices.

Regards,

Frédéric

Re: Adding host storage during advanced installation

2018-03-20 Thread Louis Santillan 
Patrick,

First, I think you're misunderstanding the order of operations here just a
bit.  `docker-storage-setup` is part of the host preparation steps and
happens on all nodes in the cluster before running the Advanced Installer.
The Container and PaaS Practice's Consulting Playbooks [0] might help your
understanding.

I'm not fully intimate with CRI-O's internals but It looks like there are
some options to set [1].  I don't see any further details on GH so I
suspect those details are forthcoming.
