Hello Andy,

you requested feedback from administrators.
Here are mine:

1st: thanks to your good job. For me I’m very pleased to get standardisated administration interfaces to that type of content.

In my daily work I miss a automatisation standard for low level tasks. Any other Administrators i interviewed agree with that. Each of them implemented his own scripts. That’s not that much efficient

A good automatisation of blockdevices should have at least the following features (for my opinion):

* Create typed Blockdevices (plain, master, clone, snapshot fom master)
* Set/Get Device Status and Parameters (used, unused, stopped, mounted, …)
* Create Snapshots from active Devices (Backup)
* Working with snapshots (Get infos, revert to, …)
* Delete typed Blockdevices if no dependencies are left

That features would be great to reach via an API

Thanks Marcus

Osqui, absolutely. I’ve looked into writing a Python wrapper for the btrfs ioctls, it wouldn’t be too difficult, and then use that directly.

Another possibility is to use libssm (https://sourceforge.net/p/storagemanager/), which would let targetd not have to handle two different APIs internally.

Could targetd work with BTRFS instead of LVM?
LVM is cool, but BTRFS is cooler!!
Thanks!

Heh, just last week I was thinking about creating some simple web ui working with python-rtslib, so my Windows-using coworkers have a way to manage LIO target. targetd seem to appear out of nowhere, and looks like a firm building block for this solution
