DESCRIPTION
System Storage Manager provides easy to use command line interface to manage your storage using various technologies like lvm, btrfs, encrypted volumes and more. In more sophisticated enterprise storage environments, management with Device Mapper (dm), Logical Volume Manager (LVM), or Multiple Devices (md) is becoming increasingly more difficult. With file systems added to the mix, the number of tools needed to configure and manage storage has grown so large that it is simply not user friendly. With so many options for a system administrator to consider, the opportunity for errors and problems is large. The btrfs administration tools have shown us that storage management can be simplified, and we are working to bring that ease of use to Linux filesystems in general.

System Storage Manager
Aims to provide easy to use command line interface tomanage your storage using various technologies like:
lvmbtrfsencrypted volumesmdraidexternal storagemore. . .
Single source of important storage information
Written in Python
Python module to use in other applications
System Storage Manager
Backends
Python modules doing the actual work
Provide information about the storage
Provide interface to call specific actions
device - pool - volume - snapshot abstraction
Problems:
Mostly calling command line tools :(Inconsistent behaviour between various technologiesWhat other backends do we want ? (partitions, images)
System Storage Manager
Commands
Command line arguments for specific action required by user
Create - volumeList - devices, pools, volumes, snapshots, filesystemsRemove - device, pool, volume, snapshotResize - volumeCheck - file systemAdd - deviceSnapshot - volume
Problems:
Slightly different semantics for different backends (btrfs vs lvm)Undo functionality ?More system integration ? (changing fstab, setting cron jobs)
System Storage Manager
More discussion
How to persuade people to write libraries ?
fs-progs umbrella library
How to integrate libStorageMgmt ?
Verbosity ?
Interactivity ?
The end.Thanks for listening.
