Storage

  • Done with local commands:
  • parted
  • pvcreate, lvcreate, vgcreate
  • mdraid
  • vgextend, resize2fs

Notice anything?

  • Both methods require a local

shell

  • The methods had an entirely

unrelated user experience

Training Costs

  • There is a completely isolated

path to learning administration

  • f either approach
  • Learning either task does not

help you learn the other

Training Costs

  • System services
  • Installing software and patches
  • Firewall
  • Performance tuning

Research

  • “The difficulty of managing these

components is directly impacting our customers' ability to consume more Linux” -- 2011 Red Hat Customer Survey Results (paraphrased)

OpenLMI

  • Provide a complete system for

System Management

  • Local and network-facing API
  • Common interface for all

subsystems

  • Built on industry-standard

protocols

slide-11
SLIDE 11

11

Blivet

  • Split from the Anaconda installer

project

  • Python library for manipulating

storage at all levels

slide-12
SLIDE 12

12

NetworkManager

  • D-BUS API
  • Consistency guarantees on

changes

slide-13
SLIDE 13

13

systemd

  • D-BUS API for monitoring

system services

  • Journald API for log monitoring
slide-14
SLIDE 14

14

DMTF-CIM

  • Industry-standard model for

system management

  • Comprehensive object-oriented

design addressing most aspects

  • f system capabilities
slide-15
SLIDE 15

15

What about simplicity?

  • CIM is a complex model that

many find intimidating

slide-16
SLIDE 16

16

LMIShell

  • Python-based scripting

environment for OpenLMI/CIM

  • Simplifies the model by

providing a pythonic interface to the objects

slide-17
SLIDE 17

17

Scriptons

  • Provide simplified interface for

common management tasks

  • Small, tightly-controlled Python

modules

  • Intended for use in larger scripts

Current Limitations

  • Non-installation storage tasks
  • Extending logical

volumes/filesystems

  • Controlling LVM/btrfs

snapshots

slide-19
SLIDE 19

Current Limitations

  • Complex Networked storage
  • iSCSI
  • FCoE
  • multipath
slide-20
SLIDE 20

Current Limitations

  • Patch Management
  • Is a particular patch (or its

successor) installed?

How can you help?

  • Help us plan the API
  • Produce a public API for your

subsystem

  • Contribute scriptons

Fedora: Try it today!

  • Available in the Fedora 18

update repositories

  • Testing and feedback highly

valued
